Seems that this hack only makes Poweramp think that 192KHz works. Please try this and do this:
Open a terminal emulator
"su"
"dumpsys media.audio_flinger"
Just don't expect miracles for now!
I've been trying for months to make Poweramp work in hi-res mode on Nougat, and finally, it works! I'm pretty sure that the DAC in use is the Snapdragon one (I'm in MiFavor 5.0 and using the super/advanced switch does nothing, not even a stutter) but it's 192KHz still, so, it's better than nothing. If anyone can try on an LOS-based ROM (where the AKM DAC is supposedly used all the time) we may get 192KHz out of that DAC!
I'm not sure if this method wouldn't work on other Android versions. But I only tried on 7.1.1.
Please be sure that you downloaded Poweramp 704 from the official forum - the one on Play store is 703 which doesn't support Hi-Res on Nougat!
I found this fix on the Poweramp official forum, by user dhenyaw.
•Download a build.prop editor or a file manager with root access. Personally, I use Root Browser. If you will use a build.prop editor, just skip the next step.
•Once you open Root Browser, your root directory will appear. Scroll down and open the "system" folder, then scroll down and open the "build.prop" file
•Once you are in build.prop, you have to find the "ro.product.manufacturer" line. In my case it was around line 30.

•Add a "#" in front of the "ro.product.manufacturer=ZTE" line, so that you can revert the change if other things break. Also, write just below "ro.product.manufacturer=samsung" and "persist.audio.uhqa=1" just like in the picture 2:
•Save the changes, reboot your phone
After your phone boots, connect some headphones, open Poweramp, play a hi-res FLAC file and go to Audio - Output - Hi-res output, then check if the active output is Wired headsets and the frequency it is outputting to.
Enjoy!
Doesn't work for me. Build.prop just resets after a reset. But even with a soft reset, Poweramp's HiFi output still fails.
Probably cuz I have the Sauron mod on my phone, though I've seen that post you're talking abt on the Poweramp forum and it does seem to work for some devices/ROMs.
Oh well, I'll just wait for Poweramp to update. Whenever that will be. Lol.

I think that's because you have write protection on. Connect your phone to a PC, enable USB debugging, open CMD and see if ADB recognizes the phone. then write 'adb reboot disemmcwp' and the write protection should disappear

Alright. I got it working but there's something I'm a little suspicious about.
It's outputting and being processed by "SAMSUNG UHQA PCM" which I don't think the Axon 7 has. Plus, I was switching between Hi-Res and AudioTrack and AudioTrack actually sounded better. Hi-Res made it feel like I was listening to music in a box.
My guess is Hi-res is outputting through the Qualcomm DAC and not the AKM 4490. So while hi res works, it's not proper hi-res, IMO.
I'm still deciding whether to regress mine to B11 MM, unlock bootloader, update to B08, flash twrp and root and get ViPER4Android in it in compatability mode for system wide effect and DAC use, and debloat it. Don't really care about custom ROMs for it.

I think I should've added that somewhere.That is called a workaround... This works by telling Poweramp that your phone is a Samsung and has a UHQA DAC. This DAC somewhat works as the Qualcomm one, so it manages to drive it @ 192KHz. And the soundstage might be a little bit worse than the AKM DAC but it's in no way canned as you say. At least not with my headphones

Yeah, narrower soundstage was what I was trying to say but I couldn't find the words. Hahah. The difference is slight, but definitely noticable. Thing is, Sauron also forces the AKM DAC to be used system wide. So, despite Hi-Res failing, the sound is still being processed by the DAC.
I'll stick to defaults for now and wait for the PA update. I'm not saying no one should try this. If it works for you and everyone trying it, cool.
Did you do this with stock? It doesn't work with dark room (a LOS rom). What I normally use is "ro.lenovo.hifi_support=true", which does work. It does say 16 bit minimum, but I think as long as poweramp is using the hi-fi mode our phone will use the high quality audio.
Honestly, I wish there was a way to check the output to see what quality is being used. Anybody have an idea of what to use? It would be good to compare stock to all these other mods/apps.

It works on stock and LOS. If you did it right your phone should appear as 'Samsung UHQA' on the audio settings of poweramp
I think Dark Rom is based on LOS, so it should be the same?
You could compare but you need (very expensive) recording equipment then compare the two waveforms. But at the same time, if you can't notice the difference, then why would you use 192KHz anyways?

Download a terminal emulator and do this:

Yeah, it seems so. The only thing I'm sure of is that doing this on the stock system of the Axon 7 actually improves the highs. I'll modify the thread to add this for now; I'll need someone to dump that file on stock with this mod later

Well I'm not sure if it actually works anywhere, but I still believe that highs improve substantially on stock with this mod (without using the AK4490).
The Samsung UHQA DAC is in no way standard. I believe it is the DAC on the Exynos chips maybe

This is the problem. It's hard enough knowing if high frequency and bit depth audio works when sources are available. You can bet in a lot of cases where it seems audio is passed correctly it's either a display error or some kind of dithering or resampling is going on.
I would love to understand how to read the process our phones take when processing audio in different scenarios but it just seems impossible. As for the stock music player working with higher fidelity files we don't know this either. It doesn't make sense for it not to but then it also doesn't make sense that a lot of software/drivers can't handle the hardwares maximum specifications.
If there was some kind of framework and a front end that could read the process it would be awesome (like graphedit on Windows) it would be useful but even that didn't work if non-standard renders we're used.
I try my best to not get worked up about it, it's very annoying to know that probably something like this will never be known..or fixed or whatever. Here we have a nice DAC with specifications to suit our hi res music collection yet probably it's all being downsampled to 44.1 or 48khz 16bit.
Hopefully the rumours are true and zte focus more on using the dac with external applications in oreo.

So upgraded to .136 and now the Sound Effects wont do anything under settings.
It only works when access via Walkman and only for walkman.
I was able to use it for any app before in 290 and from the Settings menu.
Anyone else having the same issue? :/
Yes I'm experiencing same here... I wasn't aware that it worked with walkman. I hope this wasn't done intentionally, as our phone wasn't very loud to begin with!
I also noticed that if I receive a call or check my voicemail while Sirius XM is active in the background, once the call is ended the eq is one again enabled. This leaves hope for a correction update.
It is even worst now! I just noticed that even with Walkman it will work with MP3s but no longer with FLAC files.
I am about to research how to go back to .290 :/
weird it works for me with power amp and other players. I can change the sound enhancement setting and listen to change in the effects
error.....

i upgraded from 290 and flashed the new german tft then rooted using jackie099 way, first think I test, is the sony sound enhancements, and I test always sound effects first thing as I am very critical to test sound effects and works on every player from power amp to jet player , then I installed viber and it works on the whole system too, for every player.
so no complains in the sound section for me, also bluetooth streaming works great no complains.
yes works on flac, and all other formats

ahahahah sorry about that, hope you get it soon...I can almost picture you waiting for it...
I just deleted Data partition, Format system, dalvik etc (not format internal), flashed again and while the MusicFx seems to work more consistently now from the Settings menu not just from Walkman settings, it still does not apply to any other app and it still does not affect FLAC files, only my MP3s. This is getting me pissed off...may just end up converting all FLAC to mp3 if I cant find a fix and call it a day.
I will wait for the 6802 version..maybe that will do it.
I think the phone sounds best flat without any EQ settings applied or ClearAudio+ etc.
Specially since I bought a small headphone amplifier today and connected between the phone and headphones. When pumping up the sound high enough with it (and trust me it gets high, way higher than without), the EQ settings does not make any difference to the sound anymore what so ever. Only on lower volumes. Good cheap investment I made.

I guess it all depends on what kind of music you listen to though and what you prefer in the sound.

Too many factors come into play. Headphones, type of music. amp, EARS and preferences. So that is why I no longer ask for headphones recommendations and the likes after going through a big testing phase

My sound settings work perfectly fine using Power Amp on .136
UPDATE!
I got sound enhancement working with 136 for FLAC and any other app. As I recalled I had other issues before when running non 6802 ROMS on my phone, I was still holding on to some hope that a 6802 based 136 ROM would be the one that will work...and IT DID!
I just flashed the 136 from the NUT thread and it is all working great.
PS After finishing TIBU and all updates, I lost again the FLAC and other apps using Sound Enhancements. I tested it before right after flashing to make sure it was working but no idea how something I restored could affect this since I never restore system apps and besides, I restored even less apps this time that I did on 290 so I guess we are back to blaming a glitchy 136. In any case, I am going to just use MP3 VBR at highest rate since in reality, you cant tell the difference with a phone and external amp...
I am almost tempted to flash again just to determine if it was something I restored or what made it not work again.
PS 2. Flashed again and tested flac again and it works. Hopefully I will find out what exactly is making it stop when I restored apps.
Many of you included myself complain about stock music player. It has uncountable problems but as far as I know it is the only player which can use the built in high end DAC. The most annoying thing is that it plays song in alphabetic order if files appear at all and secondly it is very slow.
I would suggest a temporary solution what I did and it works perfectly so far.
Delete all playlist (m3u, cue etc.).
Remove a metadata from files too.
Remove all songs with metadata from the phone!!!
Delete all record from "My Playlist" in the initial screen. (I was able to do it just one by one)
Reset Music Player by deleting cache and data in Application Settings
Reboot phone
Then open Music Player and play songs from Folder option. It will be enough fast and all songs appear and in filename order.
In order to remove metadata from files I would suggest using Mp3tag
http://www.mp3tag.de/en/
If you collect your files in any structure on the PC, all you can do is to move root folder into Mp3tag screen, select all songs and remove tags by right clicking. Then you can copy files to phone.
!!! Be careful !!!
Don't remove tags from your archive music folder. You cannot undo. Always create temporary folder and copy wishing music files there in order to remove metadata (tags).
Good lock!

Ok I was not so precize. Other players don't use AKM dac directly. They do it just via Android which convert all audio input to 48/16 output. Let me know if I am wrong but justify it with something please. Of course then this stream goes to AKM DAC but this not the way we wish it. I welcome any non stock player which can drive dac directly in same way as stock one does. Sooner or later it will be available hopefully but now I don't know any.
If the "Headset HiFi" control in Settings is to switch between SD820 and AKM DACs, then I'm able to use the AKM DAC with other media players that pass audio processing/decoding to the OS (as opposed to fancier players that utilize their own built-in decoding methods/codecs). In my music player of choice (Clean Music), I can switch between the two "Headset HiFi" options (Standard & Super) in the middle of a song and, after a pause to transition, hear a difference between them.

I have bad news which is good news actually. SD820 DAC is not used in A7 at all. There are two additional DACs and one ADC. "AKM AK4961 DSP CODEC, which can be considered the primary chipset for Hi-Fi audio playback and recording. The AKM AK4490EN DAC is an independent Hi-Fi audio sampler". This later is what you turn on when set "Headset HiFi" option. So SD820 ADC/DAC don't play at all.
http://www.androidauthority.com/taking-audio-next-level-zte-axon-7-706898/
and same is on ZTE site as well.
I have doubts that you can hear the difference between the two AKM chips while you don't between Clean Player and the built in ZTE player. Although I don't listen 4961 but I do Clean Player. The difference is significant especially if record is 44.1 kHz because conversion of it to 48 kHz is more difficult than of 96kHz record.

Actually, the SD820 DAC is used and enabled. People with fancy players like PowerAmp (the latest alpha) report that in the app's settings, the only DAC that shows up in the list is the SD820 DAC. No AKM DAC listed.
I'm not an audiophile or anything, but when I have Super selected, the audio has a little more of a "punch" to it, while Standard I can kinda hear a bit of a ceiling. (this is all without ATMOS, of course)

Based on these as engineer I would say that SD820 DAC is not used at all. Phone reports SD820 DAC for third party softwares due to compatibility reason but in real AKM chips works. Like I said I don't know it surly but most likely. I am also searching for the correct answer.
I believe that you hear the difference especialy if PowerAmp turns SD820 on somehow.
Otherwise the two AKM chips are different therefore they should sound differently. To hear it is just question of headphone price. Of course it is without ATMOS.
guess we need @rikin93 to use his contacts to get a definitive answer

No. It is justify my concern rather.
"Expressed in Hz, the sample rate in an AudioFormat instance expresses the number of audio samples for each channel per second in the content you are playing or recording. It is not the sample rate at which content is rendered or produced. For instance a sound at a media sample rate of 8000Hz can be played on a device operating at a sample rate of 48000Hz; the sample rate conversion is automatically handled by the platform, it will not play at 6x speed."

you missed the important part:
As of API M, sample rates up to 192kHz are supported for AudioRecord and AudioTrack, with sample rate conversion performed as needed. To improve efficiency and avoid lossy conversions, it is recommended to match the sample rate for AudioRecord and AudioTrack to the endpoint device sample rate, and limit the sample rate to no more than 48kHz unless there are special device capabilities that warrant a higher rate.

which means that it can be programmed to output at 192 khz, but 48 khz should be the default value if there's no additional hardware.
or am i just misinterpreting this whole paragraph?
so either no player can play at 192 khz, or every player plays at 192 khz

Yes, someting like that. Since it is Androud part it is 48 kHz. I used Clean player as altarnative and I prove that there is difference between this and stock.
So as I understand it says that every source is converted to 48kHz and this is sent to dac. You can play 44.1 or 192 kHz source it doesn't matter streams will be converted to 48. Stock player alone can bypass it so far. And it is important in case of CDs as well becuase 44.1 to 48 conversion is the one of the ugliest thing can happen here.

i just tested listening to some flacs in my regular player, vlc player and the zte player with my beyerdynamic custom one pro. either all of them were outputting the same format, or i am just not able to hear the difference.

So I am not fan of VLC Player therefore it is not installed on my phone. May be I felt wrongly and there is no difference because it doesn't exist at all and every player drives DAC appropriately. All I know is that I listened music by Clean Music for weeks and than I exchanged to ZTE player. Going through the music repertoire I was surprised. Anyway I am human too.
After all the fact is that you didn't here difference proves only one thing, namely you cannot hear the difference. Here and now.
I will study developer link what you suggested more thoroughly and also I am still waiting for the correct technical details from Android experts. Until I use ZTE player which works fine in above mentioned way. All song appears, all in order, no lag and sound brilliant. What else is needed?
Music Player DAC issue **Fixed**
Hi, I have a fix to using the DAC on non-stock music apps.
So I received my Axon yesterday.
Ipgraded from the Lenovo Vibe X3. I first ran in on the DAC problem on the X3.
In my experience all of these dedicated DAC phones follow the same approach, i.e., LG V10, Vivo Xplay 5, Vibe X3, Axon 7, and (I as sum) LG V20 as well.
There is already a thread on XDA explaining this in detail. -> http://forum.xda-developers.com/lg-v10/general/music-apps-using-dac-t3252596
In short, the apps listed on the V10 page will use the DAC. Although the Vibe X3 had a dedicated DAC toggle, and the Axon 7 doesn't.
To test whether the DAC is being used by a music app on the Axon 7 is:
1. Plugin high fidelity headphones (so you will be able to hear and verify the difference in music), if you can do it with regular earphones/headphones, good for you. and kickass hearing btw
2. Play music on the music app you want to test. (Refer the LG link I posted)
3. while the music s running in the background, go to Settings -> Sounds & Vibration -> Headset Hi-Fi -> and switch between Standard & Super settings.
IF that app is using the DAC, you'll notice a slight pause (when the DAC switches on/off) and of course the difference in sound quality.
Note: Switch Dolby off or ignore it when testing the app, cos for some reason switching Dolby Atmos on/off produces the same gap in playback as the DAC.
On the Vibe X3 it didn't.
I used to use PowerAmp earlier, cos I found that best for my taste.
Then I discovered Neutron, and fell in love with that.
However then I bought a DAC phone & both Power-amp & Neutron don't use the DAC(or I wasn't able to make them)
As per a lot of users online "Poweramp Alpha" can be made to use the DAC on such phones, somehow. I tried fiddling around with it, got fed-up & left it.
If someone has the patience to figure it out AND explain it to me, I'd be grateful, cos Poweramp is my player of choice in terms of UI & ease of usability.
Neutrons latest changelogs mention it can use DAC usage as an update. But I can't notice the difference in the method listed above, or maybe its referring to USB DACs.
Now my player of choice adter going through the list of DAC supported music apps is Pulsar. - https://play.google.com/store/apps/details?id=com.rhmsoft.pulsar
Reason being, I found it to be the lightest/cleanest player which supports the DAC and can relatively smoothly handle my 10K+ collection of 320kbps MP3 & FLAC collection.
You guys can go through the list of apps on the LG V10 page and decide. which suits you best.
h/t @stupc. I've found his thread to be the most informative and bang on in solving the problem of 3rd party DAC phones throughout the net. And trust me, I've searched. Went crazy trying to solve this when I first bought the X3
Hope this helps.
Mods: Please move the post/thread to the appropriate section if required and close the thread as solved.
Hit Thanks if this helped.

thank you for your answer.
the method to check whether the seperate DAC is being used supports my observation, that i wasnt able to hear a difference between all 3 players i've used.
but i guess the question remains whether the output is in 48khz or 192khz for all of them :/
I'm sceptical about the differing sound quality when switching the "Headset HiFi" setting. I noticed that the volume increases significantly when the setting is on, and goes quieter when switched off. This is a well known and proven psychological sales tactic for audio. The human brain subconsciously associates louder sound to be of higher quality.
In this case it would be very difficult to perfectly volume match the on/off setting of the "Headset HiFi" toggle for a proper blind test. I don't believe any user testing can be trusted unless it's done blind, as confirmation bias could easily take precedence.
Some good reading:
https://en.m.wikipedia.org/wiki/Psychoacoustics
EDIT: I just did some more rudimentary testing with consumer quality mp3s and the ZTE music app, toggling the Headset HiFi setting on/off. The difference in frequency response is very noticeable even when not using high end FLAC encodings. There are significant bumps in bass and treble, even when compared to other sources I have with known flat sound signatures.
So you're asking, what does this mean? There's two scenarios:
1) if the Headset HiFi toggle is indeed switching between the Axon high end DAC and the SD820 standard DAC, the Axon DAC is far from neutral and has a coloured sound with unnaturally increased bass and treble response. This is arguably positive for the average consumer who likes the visceral sensation of an unnatural U-shaped equalizer, but will be disappointing for audiophiles looking for a flat sound signature.
2) the second possibility is that the Headset HiFi toggle does not change which DAC the system is using, but rather is like a Loudness button found on many stereos. When volume decreases, the human ear perceives low and high frequencies dropping off faster than other mid range ones. Loudness buttons are added to stereos so that low volume listening frequency response sounds closer to what the ear perceives at higher volumes.
So, I've found that the audio on Lineage OS and other Roms based on LOS wasn't as good as on the stock firmware. Both when it comes to mic and headphones audio.
I followed this up by comparing the "mixer_paths.xml" files from Lineage OS between the file from stock marshmallow as well as stock nougat (A2017G model) and there are quite a few missing lines in the AOSP version and some lines that just have different values. B.T.W Is the "mixer_paths.xml" the only file where you edit values which have to do with audio?
Anyway, I then used the standard mixer file from the stock Marshmallow firmware on the Lineage OS rom and although the sound is lower than with the standard mixer file from LOS the audio is noticeably better according to my ears. (This could be placebo but I doubt it. I also use the HD 598 headphones which are quite good compared to many other headphones on the market so the difference in audio quality is easier to discover).
Feel free to try this out if you are on a AOSP rom and want better audio. Steps below:
1: Make sure you're rooted and have disabled system write protection.
2: Navigate to System -> etc -> mixer_paths.xml.
3: Cut the "mixer_paths.xml" file to a backup location in case you want to go back.
4: Download either the marshmallow or the nougat file that I've provided below and rename it to "mixer_paths.xml" and paste it in the same location. System -> etc.
5: Reboot.
6: Profit? I don't know, it's up to you if you think it sounds better. Remember that with cheap earbuds you most likely won't hear a difference, at least I wouldn't.
You can try the process with either the Nougat or the Marshmallow file i uploaded. The Nougat is a little bit louder.
In case you want to go back then just copy the mixer_paths.xml file you backed up and replace the current mixer_paths.xml file in the same directory as above. Also reboot.
Edit: As @RUNNERX pointed out, make sure that the permissions are set to 644 and then reboot to make sure it's working correctly.

I think we need a properly soundmod...
I tried with stock ROM (B19 A2017U) but it only affects the Normal Mode in headphones.
There's so much potential with this device... Ak4490 is a beast that needs to be released from its "cage".
As far as I can tell, the problem is that no custom rom is using the akm dac?
This is too bad, especially since regular dac sounds in my opinion much much better (and different) in aosp with the latest sound fix compared to stock normal (loudness being part of it). Still it is clearly not the akm dac.
On stock, both normal and superior mode have some kind of strange tuning, almost like there is some postprocessing even with dolby off. On aosp that seems to be gone at least.
It was mentioned previously that the mixer XML was ignored and all changes needed to be made the (ADC**?) files. This has since been patched resulting in proper use of akm DAC. The issues with the sound not being as good quality wise lies within these files, not the XML.

So can anyone confirm that they got the akm dac working with headphones? (and comment on the results?)
I installed the AOSP extended 7.1.2 and then magisk zip, but it didn't seem to work, though it did play louder (and stereo on speakers).
Maybe I'll try a different rom...

I was under the impression that the headphone DAC has been working since early March. The stereo speaker fix has nothing to do with the headphone DAC.

Ok, it might just be that it sounds bad in the LOS-implementation then. Thanks to senny for exploring possibilities.
Just to give some feedback
This definitely changes the sound. Standard aosp sounded kind of raw to me, with tizzy trebles, though with a lot of detail. This makes it smoother, sounds more like it should in a way, easier to listen to.
There is some loss of information though, and soundstage a bit smaller.
(I found that if I tried to copy and replace the file it didn't work (sound not working). I had to first delete the mixer file present, then paste the other one.)
After replacing the file make sure permissions are 644 and reboot.

Well good to hear that more people find a difference.
when i'm looking at this: http://blog.son-video.com/en/2017/01/test-fiio-x5-iii/
I can't help but think that ZTE could have done so much more to make the experience more complete. The fiio got viper pre-installed, and digital low pass filter to play with that are actually coming straight from AKM :
"Five different 32-bit digital filter types are available: Short delay sharp roll-off and short delay slow roll-off filters have overall short delay characteristics. Sharp roll-off filter and slow roll-off filter preserve the phase difference and a new filter that has even slower roll-off character was added to these four filters. They are selectable according to the user audio and system preferences."
We've got a phone with one of the best DAC in the world, but can't do much because android by default is limited, and it seems obvious that zte don't have a lot of experience when it comes to makes audiophile device. a partenrship with fiio, cayin, or ibasso would have been terrific, especially considering that fioo and cayin have both already launch a product with an akm4490 running on android at full potential.
Maybe we can hope that some developer with at interest in audio can unlock some of the potential.
Listening some more with the mixer files I have to say it really is a big improvement, especially with the marshmallow to me.
Whatever it is that makes it better should be part of LOS. Using LOS 14.1 with the beastmode kernal and the changed mixer paths - it actually sounds pretty good.
However, for me changing the mixerpaths breaks audio functionality. I get no audio in calls, neither speaker nor headphones. I am using the sounds fix for stereo speakers 4.1, maybe that affects it.
Does it work without side effects for you senny? Whats your setup?
No mixer_paths.xml
Hi,i have marshall london phone and i'm sure i don't have mixer_paths.xml to edit,please help me to find the file responsible for editing volume output values.

Yes, Max has finally released a test build (790) to replace 704 so those who like it, log in, download and test away. Read the first page for notes and assess any bugs. I have installed it but at work so no chance to use it yet.
http://forum.powerampapp.com/topic/...te-read-first-post-before-commenting/?page=20
Remember you MUST have a Poweramp forum account and log in to get the download.
I usually use Jet Audio HD but got a bug where it doesn't allow Tom Tom navigation to override audio focus for voice prompts so at present using Player Pro as my daily driver. Here We Go navigation works ok with Jet and Player Pro works fine with either so there's something funny between Tom Tom and Jet.
I hope the new Poweramp works ok, there are bugs and missing features so I will keep the others installed and assess Poweramp as Max addresses the bugs and rolls out more features.
Edit: Having a play with it at work, boss has left for the afternoon.
Whilst my work BT speaker (Jawbone Big Jambox) aux in is connected to my Axon 7 by wire and I played with output settings in Poweramp, set to use Audio Track, I get a marked difference in speaker volume output when switching between Headset HiFi Standard and Super in the phone audio settings. This is working better than before. I'm only on MP3 though so harder to assess as the files are not Hi Res but if I set the Big Jambox to max volume and the phone to max volume then switch from Standard to Super it's much louder and does sound better. That Jambox really cranks on this! It will overload the aux in and I have to set it back two notches so seems to be playing at too high a voltage for the Jambox input jack. Need to play with this some more. Will have a listen on my Backbeat Pro headphones tonight and also in the car on it's HiFi as that has a great dynamic range and quality with BT and wire.
Install it as a secondary player due to missing features. Max the dev will be adding stuff as things progress but I find it not quite fully functional enough to call a daily driver. I feel it's less bugs, more just not all features added and expect as he hears feedback will slowly add them in.
Here's my test setup. Dedicated page aside of my home screens with app shortcuts and widgets for easy comarison listening.
Got it yesterday. Sound-wise, it's solid. Audio flinger reports proper playback at the selected sample rate.
I had some issues with the volume whenever I got a notification even with "Audio ducking" and "short notification interuption" disabled. The volume drops, but never comes back up. I've seen on the PA forum that disabling "Float32" in the OpenSL HD settings (even if you're using Hi-Res output) fixes it. Haven't tested this yet, though. Will do it when I've got my IEMs with me.
Other than that and the obvious UI bugs, it's a good step forward, despite taking 2 years to do it.
Interestingly, the actual volume control behavior was fine on my phone. I have issues with Jet Audio though. It doesn't mesh with Tom Tom navigation app voice prompts. Got fed up with that despite the rest of it working well and great sound and have been using Player Pro for a while. It behaves reliably and now adjusted, sounds great too. Both Jet and Player Pro sound better than Poweramp for me. I have PP set as default player and is on auto start up.
I emailed Jet Audio and Tom Tom about my issue. Tom Tom have been in contact. Nothing at all from Jet. I'll probably end up uninstalling Jet.
I tested this briefly, to say it's a beta preview is an over exaggeration. It's an alpha and is way more alpha than 704. I use Poweramp near everyday and love it but I tried testing 790 but there is so much missing functionality it is just no good for a daily driver. Shame both couldn't exist on the same device, I wouldn't mind testing it then!
TBF I thought that max would have been further on with its development after the time it has taken. I know he is working on this by himself so kudos to the guy but it is so unfinished, for me, it's back to stable 704. I will try again in May with the next test build.
Sent from my ZTE A2017 using Tapatalk
Yeah, so much functionality missing, I still have it installed but it just doesn't sound as good as Jet or Player Pro for me so the point of having it at all is questionable. Max took so long to get this far with it that others have risen to the top instead.
It reminded me of Neutron a little. You have to really fiddle with it to get good sound. With Player Pro the settings are simpler but just what I need and the good sound is there. Pity the skins are ugly.
With Poweramp, I don't like the wavebar and no skip buttons. The widget wasn't fully functional etc, just not enough I liked in it for a 2 year wait. Will uninstall. See how it goes once worked on further.
Just from curiosity I had a listen with VLC. I have it for video. On wired output it's not great but did sound very nice on my backbeat pro 2 headhones over bluetooth. Not a good audio player though.
After a few days with Poweramp and finally making the jump from Nougat to Oreo, I'll have to agree. It's more alpha than the previous alpha. I lost the Hi Res option after installing AEX 5.4. Quite disappointing but it's expected. To me, anyways.
I'll keep an eye on development but I'll be using UAPP for now. Simple UI, Hi Res works great and it sounds awesome. Hopefully Max is able to refine and polish PA in less time it took him to make it.
I had another play with it last night, found that just need to route everything through HD off the QC SoC. I mostly use bluetooth these days so 24 bit off the SD820 is fine. I could lose the DAC finally and not really worry but not ready to give up the 3.5 jack though..... Sometimes it's handy.
I had 2 Poweramp widgets on an extra homescreen and couldn't remove them. Had to uninstall the app to get rid of them. Too much broken functionality but with polish I think it will be good overall.
Edit: I'd like to know how the AKG DAC is implemented in this phone. It's almost as if it routes through the DAC if using HD and Super is enabled so it may not matter what the music thinks as long as it uses hi res?
The more I use new Poweramp the better I like it. Makes me want the missing functions implemented. Definitely not giving up on Poweramp.

I didn't get anything of what you said here, but i'll tell you what i know:
-poweramp won't output hi-res in Oreo, and it will happily tell you that it is - hence, you have to use dumpsys media.audio_flinger as always
-What do you gain by routing everyrthig through the low power DAC? (Again, ZTE said it's a DAC inside the AK4961, not SD820). I wonder if that DAC actually works with 24-bit, but at least it is specced that way.
-What do you mean by the last paragraph? The DAC will output whatever kind of sound you input it, it won't "only" play hi-res.
Btw it's AKM, AKG is a headphone manufacturer
Other thing: Disable hi-res output. Use the normal OpenSL output. That way it'll sound just like good olde Poweramp
If I go back to OpenSL it sounds markedly inferior.
I keep mixing up AKG and AKM lol.
What I meant was if I have the phone set to output on Super setting and the music app is using Hi Res it does seem to sound louder and better in general, as if the phone just puts it through the AKM DAC anyway, despite the app thinking it's using the SD820. With Poweramp 790 alpha the phone will still overload the input on my car hifi when at full volume so it seems it's using the DAC, not the SoC.

As in the output setting is completely gone after jumping to Oreo. I did get the Hi Res on 704 to work when I was on 7.1.2 using either the samsung uhqa cheat or lenovo hifi cheat. It wasn't true hi res, but there were differences when I swapped between the sample rates. So it still "worked" in a way.
790's hi res worked on 7.1.2 but it looked like it was detecting the qualcomm DAC and not the AKM. I might have to resend the hi res request in the Poweramp forum.

Do you have volume issues with other players? Because ever since I installed Oreo 8.1, the volume's dropped quite significantly across the whole phone. UAPP and Poweramp play at really low volume now. Could be an Oreo thing or an Ainur thing. I'm not sure.

Nope, that's most definitely an Ainur thing. If you installed Poweramp beta, be sure to disable OpenSL ES HD output (supposedly hi-res) because that will lower the volume quite a lot.
Also install the B32+B10 bootloader if possible. That one seems to have fixes for audio.
In stock Nougat it's fine. I turned volume to max and switched between. The volume steps are different but max is fine. I found it sounded better with Float32 switched on.

I've been trawling Google Play and revisiting music apps. It seems Onkyo HF Player has had a bit of a revamp. It's getting quite good now. It has widget and notification functions etc. Still no auto start though. One thing I like is it shows the output in now playing. With my backbeat pro 2 cans in wired mode and turned off the app is playing a 44.1KHz MP3 and upsampling to output at 48K. If I go into phone sound settings and turn on Dolby Atmos then go to the headphone setting and switch between standard and super there's no difference. If I turn off Atmos and switch from standard to super it gets louder and soundstage expands. Interesting....
It still has that great user configurable parametric EQ too
Playing a hi res WAV or FLAC also shows on screen. I assume the Axon 7 won't output above 48K though? I suspect this is running off the SD820.
So if it plays above 192K what does it signify? Nothing?
Or the DAC?
I upgraded from a V35 to a V60 and an very happy with the audio quality.
However, I listen to classic rock. Now I find that either Android, LG or Verizon has limited the LG V60's volume to 75% while using plug-in headset earphones and/or plug-in earbuds.
After two months of phone calls, in person visits to Verizon and web seatching there is nothing that can be done from a user perspective, that I can find. I've tried a couple of "volume booster" apps with zero success.
I've found this limitation using LG's earbuds, every set of earbuds I own, and, with Beyerdynamic 770's (250 ohm, Note, after reading reviews, I assumed the V60 would drive those 770's w/o issue). The limitation also exists played thru a NobSound DAC.
I've seen mention of "Poweramp" in other audio related threads, used in the thread to boost output from 48khz to 192khz, which should be amazing. But there are several similarly named apps...my guess is the aforementioned app is "PowerAmp Full Version Unlocker", for $5.49. Would this help volume as well?
Is there anyway to defeat this limitation?
Even a 10% increase would be satisfactory.
What if you turn on the DAC setting in the quick-settings? I'm sure you already thought of that.

Yes, no effect.
I'm using the Neutron Player app which has a 'use on-board device's volume control' option you could turn off & use your DAC. I did this to use my tablet with an iFi DSD nano and the next time I used the [stupid] USB C to 3.5mm dongle without the DAC, it nearly blasted my ears. So if you try it, be careful when you're not using an external DAC.
The app is a pain to setup but that's because, in part, it has so many configuration options. Think Android vs iPhone taken up several notches. Once it's setup, you'll get used to the GUI/Ux itself which I did not find intuitive. Anyway, there's a free eval. version if you wanted to check it out.

Hmm....I know this kind of sucks, but how about an external DAC? Those usually work via USB C and can provide very loud, very clean output.
Op is using a DAC.

Thanks. It seems an app will be the solution. And I've seen Neutron Player mentioned in other threads.
To repeat your method as I understand it: Neutron allows me to turn off the phone's volume (which will bypass the 75% limitation) and send the raw signal via Neutron to my external DAC which will ultimately control volume?
And Im a bit confused by your advice to use caution the next time I plug in my phones directly into my phone with my wired headphone's 3.5 jack? That implies the phones limits are permanently bypassed? Am I understanding you correctly?
I'm also curious over PowerAmp app as well. Not being tech savy, intuitive is a plus.
And again, many thanks for taking the time to comment!

Right, so Neutron has another setting (and it could be Android too, not sure), that starts the app automatically when you connect headphones. Or at least it offers to start, and you can easily accidentally tap it when it pops up. I wanted to bypass my tablet's volume when I connected my external DAC, since that has a hardwire volume control so I enabled that 'bypass device's volume' control. However, later when I went to use my tablet to watch a quick video I plugged in my every day earphones, probably tapped Neutron player unintentionally, and it started playing at max volume. On my V60 phone that probably isn't super loud, especially from what you're saying. However on my Samsung tablet it was screaming loud. It happened long enough ago that I've forgotten the exact circumstances.
Anyway, that control doesn't permanently bypass the phone's volume control. You can shut it off, and I can't say for sure if it has any affect on other apps. I only made that mistake once. Later I realized the volume in Neutron was loud enough with my DAC connected. The internal volume may well be bypassed automatically. I guess I need to listen to some music again through this rig soon to test it out. Unfortunately for both of us that won't be tonight.

I haven't used PowerAmp since it first came out in the early 2000s with the advent of MP3s. But chances are it is more intuitive than Neutron Player. I'm a professional audio engineer by trade & tech nerd, yet still get caught up in the menus and different screens all the time. If it didn't sound so good and stream DSD files right along side PCM audio, and stream my entire music collection from my NAS, I'd kick it right to the curb.
My pleasure. Hope this helps! Cheers.
Any real solution for this yet? I think it can be bypassed with root access to the build prop or the sound mixer found in system/vendor/etc.
Any rooted user care to check?
Are you saying this can be fix in build prop?? Which entry?
I'm about to root my phone. Have already BL unlock it.

It should be in one of those two files. Most likely the sound mixer file though. I don't know exactly how the entry will look but i would guess something like "headphone volume limitations = max 75"
Change 75 to 100 save and reboot.
Again this is all just guesswork I'm not a developer and haven't rooted this particular phone yet and likely won't unless we get a custom aosp.
