Apparently many qualcomm chipsets have a high performance mode for the built-in DAC/Amplifier that is turned off by default. This root app enables it, and sets resampling quality to the highest setting. I definitely noticed an improvement in the clarity and separation between mid-high frequency details in a couple of EDM tracks I tried. I'm using an LG K20 plus with the snapdragon 425 chipset.

It will probably reduce battery life a bit, but the app has a simple toggle switch.

I'm thinking about this phone but can't find any info about used audio processor or just sound quality over headphones
Thanks for any help
The RN3 Pro uses the DAC/AMP DSP combination built into the Snapdragon 650 SoC at hardware level coupled with Snapdragon Audio+ processing at software level.
It doesn't have a dedicated audio chip.

Thanks for reply SharkcpN, i'll digg about thisbuilt in DAC,
anyone has experience with audio quality over headphones?
Just flash Viper4Android - instant eargasm
and i will... still i'm choosing between LG G4 and X RN3 Pro, and as far as i can read about LG G4 soud quality, i can't find anything about xiaomi. None of my friend using it so i can't hear for myself.
del
As per Qualcomm it used Qualcomm Hexagon DSP + Qualcomm Immersive Audio if you are rooted the VIPER4ANDROID is the best choice..
I'm using RMN3 SD with VIPER4ANDROID, the sound quality over earphone is excellent..
use google play music there u can tweak snapdragon plus equalizer set surround sound at MAX 100% ,set Reverb to small room then go to setting and switch on MI sound enhancer only then u will feel the real output via headphone jack
Default equalizer is very good, I havea really nice sound with my xiaomi piston 3
Anyone tried messing with mixer_paths.xml?
Try this out

I got my LG V30 this week but I can't tell the difference between dac on or off. I've used Tidal on Hifi mode, streaming a 24/192 from the NAS using Shure se846 earbuds. When I toggle DAC on/off and don't look, I can't honestly tell the difference even at high volume. I would expect the dac on to be louder?
It sounds nice but compared it to my old Galaxy S7 no major difference.
Can you audibly tell when dac is on or off? Is there any way to get diagnostics or geek stats to see if something is wrong?

Same here, LG V30plus. To me, with or without DAC, almost same quality, using tidal hifi, lg music player, spotify. I can say that on S7 the bass was more present, using the right setup and a pair of Soundmagic E10. I am little bit disappointed but maybe we are rookies in using the right setup or headphones. I have the BO-s that were in the box with the phone. and the volume is way too weak.
I've got my V30 for a week now. First time I listened with pretty decent (low impedance) in-ears I had the same impression as you. DAC on sounded even worse than off. Second time I did an A/B comparison against an Oppo find 7 which is no slouch in sound output, and everything was fine. DAC on was better then off and my V30 was on par with the Oppo. Today I was in the mood for some music, and DAC on is again bad.
I have no idea what is going on, besides a bad manufactured V30. Or being a rookie
@gjvdkamp
Shure SE846 has a 9 Ohm impedance only. To trigger the Dac you have to use a >50 ohm one.
@all
You can easy check the Dac with
Hi-Fi Status (LG) app. This app is currently for free on Google Store.

Hi Fi Dac works with < 50ohm device, the High Impedance mode needs > 50ohm.
You can trigger the Quad Dac in the quick menu or hold the icon for more options.
The Hi-Fi DAC is not amperage dependent. It's either enabled or off when you insert a headset or device into the 3.5 jack. Of course, first time, you will have to activate the Hi-Fi DAC on the main drop down menu, and you can always turn it on or off when a headset is connected. Amp section should automatically determine what type of amperage device is connected to the V30 and adjust high impedance mode accordingly. Or, you can force a higher impedance mode with an inline connector if you prefer.
Hi all,
I searched through a lot of forums and video reviews but couldn't see anyone doing a clear review of the quality of sound from the headphone jack.
I'm considering getting the F1 to replace my Axon 7 so wondering if the sound quality will be much worse?
If you can compare it with Axon 7 it would be great.
I knew about the GSMarena test of audio quality but that may not be the same in real life. Also it seems that the phone didn't utilise the Snapdragon 845 chip's audio capability which should be better than older phones.
Thanks
Anyone?
I don't know why people ask this question on every phone's page? IF there is no dedicated hardware used for audio it will should sound same as all SD SOCs. You can try all kinds of fancy software optimisations and equalizers it doesn't matter as long as the audio hardware is the same.
For answering your question in particular, IIRC Axon 7 has dedicated AKM 4490en for processing audio signal which is top notch. So NO Poco or any other phone with SD SOC audio is not even come close in audio quality for that matter. And since we are there take my advice and don't sell that phone(AXON 7). For it's audio capabilities you can take out the sim and can use it as a Android DAP for as long as it can serve you. A simple android DAP sells for quite a bit. I was myself very interested in this phone for audio but since it was not available in my country I went for LG V20 which I sold 2 weeks back.
I haven't had the pleasure to try the Axon 7 before, but I have used the HTC 10. The amp on this thing is weak,on my IEMs I had to crank it up to around 60-70% to get to my usual volume. Compared to a HTC U11 dongle (with DAC in it) that I have around, the dongle simply sounds better.
With all of that said, the fact that the headphone jack is there is still very much appreciated.
The headphone lacks depth and bass though it can improved through through Mi Sound Enhancer but still won't be somewhere near phones with built-in DAC.
We can hope for upcoming Dolby support soon.
I read a lot of threads back when the Poco F1 was released and a lot of people complained about low volume of audio output from headphone jack and low clarity.
It is very hard to compare audio quality if you dont have 2 devices side by side.
So I request people who have the Poco F1 and some other phone like the Redmi Note Pro, Moto, Nokia etc to compare the volume and audio clarity.
If you have MIUI device use the same audio settings.
Can anyone please do this?
Edit: Sorry for double post. Thread was not showing up so I replied here.
I have Axon 7 and POCO F1. I think that quality on Poco is great. When i used earphones with my axon 7 with low impedance (KZ ZS6 - 16 ohm) i heard hiss when i turned wifi on... On poco F1 i dont have any problemes and quality for source Tidal (HIFI),Spotify (Premium), Youtube Music is very good. (headphone - beyredynamic COP) . In next days i will have external dac SMSL IDEA. I will try compare sound quality between poco inernal dac and my new external dac.
+ Dolby is very very bad. On axon it was first thing that i turned off. Viper FX is best.

Duude, we have the same IEM, KZ ZS6. Poco does create a static noise in a specific situation (can only be heard when nothing is playing):
1. Enable tap to wake.
2. Don't play any audio with Poco.
3. Connect your IEM.
4. Lock the phone or just manually turn-off the display.
5. Rest your whole hand on the LCD, you'll hear a static noise and mine was prominent on the left channel. I noticed that the static noise is stronger when the LCD is turned-off.
How did I find it?
Since fingerprint cannot be disabled, I always place my Poco in my pocket with the LCD facing my leg and I always hear static noise every sone transition.
I disabled double tap to wake due to this.
Weird interaction. lol.

Yes, on my Beyerdynamic COP I need set volume to 40-50% for comfortable listening (Spotify). I think with all IEMs or over ear headphone to 64 ohm you will not have problem.

You can get a little more volume, but not without the cost of increased distortion. However, you can enable stereo mod, and you will get more bass, because the top speaker has a deeper low end, and of course the total loudness will be increased.

There are a host of audio "improvements" if you're rooted with Magisk. Check out the app or the threads here on XDA

Arise is bloated junk. The stuff the Arise team added never worked. UltraM8 proved this himself. The V4A will disable the quad dac.

Most Dolby Atmos ports don't actually work. There was 1 guy who used to be able to port it. Only 1 guy. Also that port did not work 100% either.

I believe this is untrue, and nevertheless, he wants to use it to tweak the loudspeaker, so it's unrelated to the quad dac.

Don't believe it, that's your choice. Many threads on XDA that backs this statement up. UltraM8 for instance backs this up. His mod is also not 100% working with the quad dac. He SAID this when I questioned him on this. It's also in his first post.
"he wants to use it to tweak the loudspeaker, so it's unrelated to the quad dac"
This IS related to the quad dac since you can enable it for headphones.

The quad DAC in the V30 only gets called into action when there's an output device (headphones/earbuds/IEM/line-out cable/etc) attached to the headphone jack. It's possible using a USB adapter to get the quad DAC output pushed through the USB-C connector as well (from my understanding of it), but the internal speaker(s) in the V30 don't ever get output from that quad DAC.
The internal speaker(s) are powered off the Qualcomm DAC in the 835 SoC so there is going to be a limitation on what you'll be able to do, probably the best anyone can hope for it dropping the mid-range and highs a bit and adding a bit more bass but we're not talking about frequencies lower than about 80 Hz 'cause those little drivers just can't do it.
The internal speaker(s) are what they area, and nothing is really going to improve upon that. I will say my V20 had substantially louder output overall (I don't muck with the audio levels like I used to with edits to the mixer_paths.xml file) and it had a lot more low end aka bass response as well. I have no idea why the V30 is worse in that respect, but for me I use headphones or my Monoprice 9927 IEMs for listening anyway about 98% of the time. Sure I do have my phone on sometimes at home and listen to things but I have a pretty awesome little Omaker Bluetooth speaker I can feed the audio to and get the bass if I want it.
Hello, I was reading something that the V30 only uses the ES9218P DAC Chip when you insert a super high quality ear phone, can some one comment as to whether this is true? And if so, is there a mod or something to force it to use the chip at all times?

If you're on stock firmware the quad DAC is used all the time. However, how many of the quad (four) DAC channels are activated depends on the impedance of your headphones. Usually about 50 ohms for all four.
There are mods (requires root) to force High Impedance Mode (HIM) no matter what headset you're using. That's not always best if you're using low quality headset/earbuds.
I use a version of forced HIM -- using Anxious V30 mod, but she toned it down in later versions of the mod to only half the volume for earbuds with less than 50 ohms which didn't naturally activate "normal" HIM. She called it faux HIM or other names because some audiophiles argued with her terminology.
They'll probably argue with mine also -- but I'm explaining it so it's easily understood.

I will post a link that has a possible work around. I use it, but not sure that it is needed to enhance your low impedance phones. You can try it and see, I guess. It will be in the first post of the link as a "spoiler".
I also have downloaded an app that let's you know if it is in normal, external DAC (the work around), or HIM mode. The app is, "hi-fi status LG".
https://www.head-fi.org/threads/music-apps-tips-and-tricks-for-the-lg-v30.868978/
Use it or not. It may help or not. I do use the work around with my low impedance head phones.
The impedence modes only bump up the amplification to accommodate power hungry earphones.
There is no impact on sound quality. You should not worry about it, just plug in your erphones and enjoy.
