Ok I searched for Solution on google, it seems no body else is facing this issue. So here is my problem I migrated on to v30 from v20 and I noticed that whenever i play a song with quad dac on there is a very audible static noise in the background, like if the mic on or a better example would it feels like the song is being played on a radio.. where along with song there is a hint of crackle and white noise. My V20 never had this problem.
Is anyone else facing the issue, BTW I am on Philippine oreo KDZ, and will LG cover the warranty or should i wait and flash Indian Oreo to claim warranty??
did you try different audio sources, headphones, also try some speakers

Look: you ever used the "high performance" mode of the WCD9xxx in-built DAC of any previous Android phone ?
This raises up the output but also comes with the cost of higher "white noise" / static, etc. - this in turn is able to drive headphones with a high impedance Ω
The same applies to the dedicated "quad dac" - it has high output by default and thus is to be experienced best with "high quality" (well, most high quality headphones have higher impedance than the very cheap headphones).
There's a noticable difference for me when switching between e.g. the EP630, Xiaomi Pistons and the provided B & O Headphones that came along with the V30.
So there is NO issue and there is not really a solution but to use it in the way that it was meant to be used

If a DAC has distortion and audible static interference then its not doing its job. In simple layman terms, Switching on DAC should improve sound stage and frequency response and it is noticeable on any even basic headphones. Like I mentioned in my post I have Lg V20 too, and the DAC on that phone doesn't have any of the issue which i mentioned about my V30, to which you say is not an issue. Also Headphone (Mi Piston) is not an issue.. coz the same headphones works perfectly on V20..

well, it could be due to how the driver & kernel is compiled (so it would be an out-of-the-box issue) - I've experienced this kind of increase in static noise on the Z5 once going from fstack-protector-regular to fstack-protector-strong (more functions protected or "tainted" in that case)
https://outflux.net/blog/archives/2014/01/27/fstack-protector-strong/
https://lwn.net/Articles/584225/
https://en.wikipedia.org/wiki/Buffer_overflow_protection
Since the stock kernel is built that way by default the audio output quality could be somewhat worse compared to V20 (if there the kernel was compiled with fstack-protector-regular).
I can clearly hear how there's some distortion and audible static noise when the screen is off, quad dac enabled and changing volume (up or down) - the amp first is gone, the output is much more silent and there sound is less clear - more static can be heard
I've attributed this to the quality of the audio tracks I'm listening to - since with fully digitally created tracks this didn't seem to occur that much.
Also there's one particular issue I had forgotten:
Once connecting the Xiaomi Hybrid Pro and having Quad DAC disabled (so the stock WCD94xx used) either on left or right channel (every several seconds) there is solely (no other output) very loud static noise while playing music [similar to the static on old-ass TVs where only static is being shown and similar sound played],
when enabling quad dac/ES9028PRO it's gone. No matter what audio track is being played this was happening - I wasn't sure whether this was a software or hardware issue and since this was only happening with one particular type of headphones/IEMs I keep the phone so far.
Since you mention that the static noise appears along music output I doubt it's a similar issue you're observing.

Yes I did.. And by v20 i mean i tried all Flac, same mp3 on both the devices, wired speakers, headphones, so it doesnt seem the problem is with any of the external devices, , tried different music player, same problem it has to be issue with V30's dac or the headphone jack its just when i start playing a song with Hifi option on, the static and light crackles starts and when the song finishes playing or I pause the song the noise stops after like 15 seconds or if i turn off the dac the noise stops immediately. But toggling hifi option on and off without any music playing the issue doesnt exist, its just when a song starts and DAC kicks the issue appears, so i doubt its even headphone jack

I wish i could have tested on indian nougat when i had it, to see if it is oreo related issue, now i have to wait for Indian Oreo to see if that rom has the solution. I think Ill probably send it to LG to fix it while its under warranty
Stock Nougat, just going to start the bootloader unlock process, but sonically it's been flawless, orgasmic actually, with Sennheiser 6xx's, Etymotic HF2's and ER4's as well as BT to a UE Boom. Only the occasional crackle because my HF2's cabling is getting old, so sadly I'd think you have a bad unit.
Even I am experiencing the exact same , I'm on Indian Oreo kdz. When I turn on high impedance mode with sennhieser hd 598 and then connect it to my ath e 40 , I get a continuous hiss throughout the song.. sometimes it's irritating really.. I want to ask if someone who has rooted and using whiskyomega mod having same issues ?
By the way I don't get it on hd 598 , it probably dampens it..

The HD598 is 50 ohms (more resistance) while the E40 is merely 12 ohms, with a dynamic driver, I am guessing fairly sensitive. I wouldn't use HIM with earphones like that in the first place. That said, V30 is known for having a very low noise floor, so I wouldn't expect hiss, even with HIM and sensitive earphones.
Which music player do you use and what is your music source? Unfortunately V30 will upsample 44.1Khz sources (i.e. all CDs and most streaming sources) to 48KHz before sending it to the DAC. This should not be audible in most cases, but a few people are able to hear it when using very sensitive IEMs (typically balanced armature drivers). It is described in the opening post of the thread linked below:
https://www.head-fi.org/threads/music-apps-tips-and-tricks-for-the-lg-v30.868978/
The way around it is to use a music player that bypasses the standard Android audio path, such as UAPP or Neutron, both of which use their own audio driver that sends music directly to the ESS DAC.
Another possible explanation is if some EQ or other processing in your music player is messing with the data before it reaches the DAC. If you try playing with UAPP using Bit-perfect mode, that's a great way to determine if it is a hardware problem (which is possible) or something in the digital audio path.

This sounds similar to what I experienced with my V30S using Beyerdynamic iDX200 headphones with the extension cable design*.
At first I thought I had received a defective V30S. Then I found the problem was limited to those particular headphones with their included extension cable. With the extension cable removed, and with any other headphones, the V30S audio quality problem disappeared. And the iDX200 sound fine on my other phone, as long as the extension cable connection is clean (it is prone to signal degradation by contamination).
My guess is that the V30 system that measures load impedance on the 3.5mm jack has some kind of anomaly related to imdedance/VSWR imposed by the connection of the iDX200 extension cable, even if that connection is clean.
Try different headphones.
(* The iDX200 cable is too short by itself, it has to be used with a short extension, either the included one or another.)

I have found a solution!!
Go to hifi settings in balance section, reduce the volume from left and right to as low as possible, I've kept it zero and just raise the volume to your liking..
In my case the hiss has reduced drastically to the point I can ignore it ! Hope this works for you!

Great! I'm glad you like it.
And interesting that it solved the noise problem too. That most likely means it was the artifacts caused by upsampling 44.1KHz to 48KHz (performed by Android's standard audio path) that you were able to hear.
UAPP is my favorite too, both for its features, its ability to play redbook (44.1KHz/16bit) without upsampling, and for its user interface. Neutron can do that too, but I could never understand its user interface.
In UAPP, under HiRes Driver flags, make sure to select the MQA flag if you play MQA files or streams. This will ensure that the ESS Sabre DAC is fully utilitized for MQA playback.
Correction- high impedance mode when switched on, even this app makes the noise , I had tried without the high impedance mode..?
but still ,otherwise quality seems better than the stock ! ?

Something is wrong, that just doesn't make sense. If anything, there should be less noise (if the theory of HIM activating more DAC units is true). And in any case is the V30 known for having very little noise, in any of its modes.
How do you trigger HIM? If you plug your headphones/earphones in directly (no adapters of extension cables) is volume loud enough?
If you play music through an impedance adapter, then I suggest you don't. Unplug the adapter once you've achieved HIM, then plug your headphones/earphones into the extension cable (or TRS adapter).
And if you don't need HIM to drive your headphones/earphones loud enough, I suggest you don't need it for maximum sound quality. The V30 was designed to adapt its output mode to the connected headphones/earphones. While it fails to do that correctly with planar magnetic ones, it does it correctly on most others.
Still, unless you are playing through an impedance adapter (which will change the frequency response of your headphones/earphones) or through a poor quality extension cable or TRS adapter, I cannot see a good reason why HIM should have more noise.
Ath e40- when i connect without adapter, loud enough, okayish sound.. Just like any other device..
There was this one time the high impedance mode got activated by mistake, mustve been a glitch! but my god the sound !! - more punch, more soundstage , even minute details audible , more dynamic!! way more louder! Then i searched around and found a way to trigger it everytime by using ath cable extention and sennhieser hd 598 , then unplug senn without unplugging the cable And then connecting e40.
This time i could hear the hiss.. Whenever i plug the earphones only, theres no hiss, and quality is okay.. even though the hifi option is on. i guess it just uses the snapdragon dac or whatever.
to summarize-
if i connect the cable first and then e 40 - sound is louder and okay.
only e 40- sound is okay.
senn and then e40 (to enter high impedance mode,probably uses the quad dac for real this time)- sound is amazing!!!! but with hiss...
I've only used the stock music player uptil now.
now i use uapp- it still gives me the hiss when high impedance is on. otherwise the sound is a bit better than stock music player.

Just wanted to know if anyone else noticed faint buzzing/scratching/hissing noises coming out of their headphone jack...
(and yes I have tested several headphones/earbuds and tested with my MDRv6's all with the same results. Its definitely the phone not the headphones)
When I insert my headphones there is a quick beeping sound that plays for a second or so then goes quiet.
When music is playing, especially soft music (a particular song was Instant Crush; Daft Punk) there is a hiss in the background, specifically when certain tones play.
It was terribly noticeable right at the beginning of a few songs, especially the one I listed above.
I also have button sound effects enabled. So When I press one of the soft UI buttons it makes a tick noise. However for about 5 seconds after the tick there is a long hiss then silence until I press another button.
The volume of the hissing/scratching noises is directly related to the actual volume of the device and the note playing.
Im on stock build 11c w/root, and I havent found a lot of info about this problem.
Just wondering if anyone has noticed this, or if this is a known issue?
If your phone is warranteed, I would bring it in
The G3 boasts an AMPLIFIED 1 watt sound speaker, which means there is a powered sound processor.. Unless the jack needs to be cleaned, I would lean toward thinking there is a defect in your phones jack, or sound assembly. I think its more than likely a defective jack, especially if there are no sounds like you are describing when headphones are not in use
Yeah the phone is brand new. I think I'm going to RMA....

Just got my G3 a week ago and didnt use headphones until I read your post, I tested many different songs with different players, stock player, google player, Iheart radio, pandora, etc, headphone sound is crystal clear on mine, I dont get any beeps either like you described, I did notice you need to make sure the jack is pushed in good and tight, I put it in and thought it was all the way in and sound was crappy, pushed a bit harder and it clicked in good and sound was great, do you have a case that may be preventing the jack from being pushed in all the way, I had a phone in the past that this happened to me with, had to cut away some rubber on the jack to make it fit snug, if none of those are the issue, I would look into a warranty claim. I am using the beats audio earbuds that came with my HTC M7 I had before this phone.

That could be the issue. I know on the 2012 Nexus 7, it's really bad. It's supposedly due to the microUSB port and the headphone jack sharing the same circuit, or some engineering thing like.
Wonder if it's the same or if they didn't shield the headphone jack very well and it's picking up interference from the microUSB port when charging?
I didn't want to leave this up in the air so I figured I would post an update.
I replaced my G3 through Verizon for a brand new unit. My first phone was of an earlier batch (came with the 10b update) the second one was of a later batch and had 11b pre-installed.
Both phones had the same issue. There is a hissing noise/distortion that comes from the headphone jack. Even when not playing music.
I noticed it on other phones too but not anywhere nearly as much. I understand that any audio source is going to have a little background interference but the G3 definitely has a more significant issue than others.
However it seems to be entirely dependant on what headphones you are using.
1st. I tested first with my Sony MDR-v6's which the problem is most noticeable on. Extreme hissing/background noise.
2nd. Then I used a pair of Audio Techina ATH-PRO500's and the problem was almost unnoticeable.
3rd. I also tried my Steel Series Siberia v2's and the problem was again almost completely gone.
4th. I also used my receiver at home. JVC 5.1 channel receiver with RCA speakers and a Kenwood sub, didn't notice the issue at all. However there where some occasional strange popping noises when no music was playing I didn't get on my GS3 or other MP3 player.
5th. Finally I tried the ear buds that came with my Galaxy S3 and the distortion was again totally noticeable with and without music playing.
This is most definitely an issue that totally depends on what headphones you are using not sure if it has to do with sensitivity or impedance (this is what most people think) however it is most definitely an issue. I saw a few threads saying that audio issues were a problem in Android 4.4.2 however LG/Verizon have yet to release a stock base on anything but.
I suppose I could flash AOSP 4.4.4 and see if the problem persists but I don't know if that would even be worth it.
2 phones and 4 headsets later this is starting to seem like either a software or a design issue.
However I have nothing but good to say about every other bit of this phone. Really besides the audio jack top notch all around.

I might have found a workaround for this
I have tested 3 LG D855 and all of them have noise/static/high-freq leak from the processor out to the headphones. It might be a faulty design for the headphones amplification stage for headphones (when the headphones logo appears on the status bar). However, when using line level output (the jack appears on the status bar) the problem does not reproduce.
Therefore the workaround I've found is to trick the phone into line level output mode and then plug the headphones. To do this you need to plug in a 3.5mm jack extensor or a 2-to-1 3.5mm Y-adapter with no load, that's it, with nothing connected to it. At that moment, the phone will activate the line level output mode. Only after that you will connect the headphones, and you'll see there are no artifacts on the audio.
That being said, I'm not sure this will work with all kind of headphones as I have only tried with mines that are low-impedance ones, but on those it works perfectly. To be checked if the level of the signal in line mode is enough to drive other headphones.
In any case, it is a shame this happens with a high-end and expensive smartphone. I was hopping this will be fixed in a newer hardware revision but I got two replacements of mine and no luck. I have read somewhere this might be a flaw in Snapdragon 801, as it integrates completely the signal routings but isolates badly highfreq noise from processor stages, etc. etc. but I do not remember where I did read it unfortunately.
I hope this helps!

Ive been having the same issue. I have a pair of Shure SE846 which are about 8ohms. I experience the poor audio, especially the noise in the left channel. I find that placing a call and then listening to music removes the left channel static but the sound is still kinda bad. Ill try your suggestion tonight and post back. Just wanted to let you know your not alone.
I despise my G3 because of this. Im looking to get a new phone unless I can fix this.
Nope, my sound is perfect on my high-end Sony over the ear phones. Crystal clear on pure stock G3 .
I haven't noticed any artifact issues on my phone when using headphones, however when I plug it into my vehicle and also plug in the charger that causes everything to go nuts. The USB interference causes a crazy amount of excess noise. I haven't ever actually tried listening to headphones while charging, so in the car is the only time I've ever noticed it. The same issue occurs when I plug in my Galaxy Tab Pro into the aux jack and charge it at the same time, so this is definitely not unique to the G3. I wish all phones had as good an amplifier as my HTC DNA does, I still use that thing for music because the sound is so good.

I'm having a different audio problem.
With headphones plugged in and listening to music using any player, the right side sound emits distortion/hissing noise at a certain frequencies. When I tested it with plugging a 3.5mm to 3.5mm to an external amp (JDS labs c5) the distortion/hissing noise is completely gone. So it's definitely not a faulty jack
The hissing is evident at the beginning of (first few seconds) Tina Area's Still Running and You set fire to my heart .
I'm testing it with sensitive iem (Westone Um3x).
So does this mean there is a problem with the internal amp of the g3 or more to do with the os bug that can be solved with a custom kernel or update.
Is this a common issue found on all g3s?

I have tested 3 LG D855 and all of them have noise/static/high-freq leak from the processor out to the headphones. It might be a faulty design for the headphones amplification stage for headphones (when the headphones logo appears on the status bar). However, when using line level output (the jack appears on the status bar) the problem does not reproduce.
Therefore the workaround I've found is to trick the phone into line level output mode and then plug the headphones. To do this you need to plug in a 3.5mm jack extensor or a 2-to-1 3.5mm Y-adapter with no load, that's it, with nothing connected to it. At that moment, the phone will activate the line level output mode. Only after that you will connect the headphones, and you'll see there are no artifacts on the audio.
That being said, I'm not sure this will work with all kind of headphones as I have only tried with mines that are low-impedance ones, but on those it works perfectly. To be checked if the level of the signal in line mode is enough to drive other headphones.
In any case, it is a shame this happens with a high-end and expensive smartphone. I was hopping this will be fixed in a newer hardware revision but I got two replacements of mine and no luck. I have read somewhere this might be a flaw in Snapdragon 801, as it integrates completely the signal routings but isolates badly highfreq noise from processor stages, etc. etc. but I do not remember where I did read it unfortunately.
I hope this helps!

Hi! This worked perfectly for me but for me instead of tricking the phone into line level output mode, I detaching one side of my headphones before plugging it into the headphone jack then reattached it afterwards. I'm using pair of sensitive iems (Westone um3x rc)
Everything is quit with no distortion, just how it should be!
One thing, is there an option within android or an app that can permanently enable line level mode ever time headphones are plugged in without having to trick it.
If so, I won't have to sent my phone for repair!
Also are there any disadvantages for using line level with headphones?

Using line out shouldn't make any difference on audio quality. It only disables the remote (buttons and microphone).
Would also really like a way to force the line-out mode. Btw, does this affect all G3s? Cause right now I'm not sure if it's worth the hassle of replacing it.

I know but some how using line out causes the hissing from the right side to go away completely. Strange huh
Are you also having this problem?
I also don't want to return mine if it exists in all g3s and there's a easier work around.
Yea same thing. I have artifacts in the left channel except when I manage to force the phone to recognize the headphones as line-out. I did this with the adapter to test it and it's impractical if not impossible to use the same adapter all the time.
I'm gonna try doing this right this moment to see if it works: http://forum.xda-developers.com/lg-g3/help/hissing-noise-left-ear-playing-music-t2804065/page17

I don't use earphones with a volume remote or microphone so that's not a problem.
It could be more to do with the increase in output impedance but I might be wrong cos the volume level is identical to headphone out.
I'm also getting a lot of static background noise but it disappears after making and hanging up a call as mentioned in a thread.
But yeah a permanent fix by forcing it into line out or doing some changes in kernel would be much more convenient

Please excuses my ignorance but I know nothing about accessing and editing a ROM.

I don't have a V30 yet. Saving up for it right now. I do have an audio question though....
For a typical, non-Quad-DAC phone, I realize that an aux cable between the car's head unit and the phone's headphone jack should sound better than playing music via Bluetooth due to losses from Bluetooth.
With that said, with the V30, and using an aux cable to the radio's input jack...would enabling the Quad-DAC make any difference to the sound quality? I assume that the DAC and amplifier are designed for headphone use where headphones typically have no external power other than that provided by the signal. But, while using the aux cable and going through a car's amplified radio head unit, would the DAC give you anything above what the radio itself provides? Does the fact that the radio has a powered amp negate what the V30's DAC provides?
On a similar note...my old LG Optimus G Pro (currently my EDC phone) when connected to my car via Bluetooth...when I play a song on my phone, and then play the exact same MP3 file on an iPhone, the iPhone sounds better. Cleaner, clearer, better dynamic range and stereo separation, yet it's the identical MP3 source file. Is that a hardware issue between the 2 phones, or is it a software/firmware issue?
Good question. I haven't tried it in my vehicle yet. (I use thumb drives to listen to music in my truck.) I will try and report back. You can toggle the DAC on and off.
I'm interested in me too. I listen to music in the car via bluetooth. that is, V30 connected to the car stereo.

Tl;DR - aux will usually be better than BT. Make sure your source files are high quality. And lastly, USB transfer or stream will be the best quality in almost all scenerios.
Okay, a couple basics. DAC stands for Digital to Analog Converter. Your car system has a DAC for playing digital audio files. I suspect most decent car audio systems perform better DAC than most cell phones. While it may be better than most cell phones, I doubt our V30's would be better than most new car systems.
With Aux, your phone is doing the DAC and sending an analog signal to the car. Then you car is just amplifying (as per you eq sertings). With BT, your phone sends a digital signal, which is then run through the car DAC system.
Here's where it gets complicated. There are a few different codecs that can be used to compress the transfer, and then quality settings within them. In theory, BT can be a very high quality transfer with near 320kbps sound... BUT ... You get into compatibility issues. This would very likely be why the sound from the iPhone generated playback sounded better than the other phone; it is using a different codec or higher bitrate on compression. My post is already too long but search for BT codecs if you want more detail.
A few tips. Make sure your source file is good!
General convention is that a 128 is comparable to FM radio. 160 or 192 is generally felt to be similar to CD quality.
Check the setting on your music app. In spotify, both streaming and download bitrate settings can be bumped up. Jist be aware of your potential data and storage issues.
Conclusions:
Phone DAC won't come into play for BT transfer. Hopefully your car system has the codec compatibility for high quality transfer. If so, go with that. If not, then AUX will be better.
V30 DAC seems to be high quality, and will function for aux transfers. The car system will then apply analog effects (bass/treble or EQ boosts) during amplification. You will have to play with the settings to see what sounds best to your ears.
A final consideration: Take a look at USB cable connection. A modern car audio system will likely be able to take advantage of digital transfer via USB. This may take the form of seeing your phone as file storage or may allow for your phone to stream music. Either way, assuming a good quality car system, your car can playback your high quality files without any losses that come with BT. If the DAC in your car is better than the V30, then this will be best.

Audio DAC on the V30 is mostly better than most car stereo converter. Heck, most laptop / desktop PC have lesser DAC than the V30.
BUT, in order to use it rightfully, you need high quality audio files. No matter how good is the DAC, playing 160kbps mp3 won't make a difference... Playing 24bits flac, on the other hand, will show you the difference between them all.
If you want, you can downlaod the sample on this site to test out the result:
http://www.eclassical.com/pages/24-bit-faq.html
That being said, the V30 pluged in the AUX will most likely sound better than mp3, as long as the sourde file are higher in quality.
Some of this stuff has already been mentioned, but here's my experience. I have a rooted V20 (waiting for bootloader unlock for US998 V30 before I buy it) with V4A. I also have a $4k custom audio system in my car with an amp, subwoofer, and aftermarket speakers. I love music and it's the only reason I've bought V20.
If you use BT, V30's DAC won't be used (as has been previously mentioned in this thread). If you use AUX, it will be. In my experience, AUX provides *far* better sound quality than BT. As far as Hi-Fi DAC, I discernibly notice a difference only with lossless audio; not so much with MP3. That difference, however, is enough for me to stick to the LG V* line and not switch to google pixel, which I would have done otherwise.
You should also keep in mind that not all cars will allow you to play audio through USB-C. Digital audio through Android is not nearly as widespread supported with car manufacturers as with iPhones.
If you have a good audio system in your car, you will be happy with the sound quality of your V30 through AUX, much more so than through BT.
Just for comparaison;
AptX as a bitrate of 352kbps
AptX HD as a bitrate of 576kbps
Mp3 @ 320kbps will stream with AptX with no lost,
Flac @ 16 bits have a bitrate around 900kbps (more or less, depending on many factors, but you can average on this)
Uncompress 16bits @ 44hz stereo is ~1400kbps
The Audio Dac of the V30 can run above this.

Most online streaming sources utilize same compression as MP3, so I personally don't notice much difference whether HIFI DAC is on or off. I'm sure if I was using something like Tidal for streaming, which steams lossless audio, the difference would be there.
Just got this new V30S going, discovered VERY poor audio quality on the 3.5mm output.
Doesn't matter whether the hi-fi DAC is enabled or not.
The system also does not even recognize my Beyer iDX200 headphones unless I connect an extension first.
I'm thinking I got a defective V30S. Am I missing something here? Headphones (edit: Beyerdynamic iDX200) sound excellent as always on my other phone.
Edit: Weird problem apparently related to impedance of the Beyers extension/connector. They work no problem and sound great with other devices, but the V30S has some issue related to impedance checking of the extension and connector. If I connect headphones without the extension they work ok. Guessing something related to VSWR.

Yeah, I think you may have gotten the low impedance portion of the DAC when you should've gotten the "Advanced" Higher Impedance setting. The sound quality of the phone & the DAC isn't actually bad, it's just a particularly bad coded file on part of LG. They apparently messed up a file named "mixer_paths_tavil.xml". Whiskeyomega has more information about this on his sound mod page: https://forum.xda-developers.com/lg-v30/themes/whiskeyomegas-v30-sound-mods-t3757115

There was more to this problem them just low impedance detected.
The Beyerdynamic iDX 200 IE headphones incorporate an extension, the primary cables connected to the headphones themselves are too short without the extension. This arrangement was somehow causing a fault condition with the V30S, it would cause an odd noise (audible in the headphones) when first plugged in to the V30S jack, then fail to even register that headphones were connected at all (implying impedance way out of expected range). If the extension was plugged in to V30S jack first (sans headphones), the HiFi DAC icon would show, then plugging the headphones to the female end of the extension would enable the headphones to work - but the sound was not only very weak, it was horrible and garbled, with what sounded like artifacts from the worst low-bitrate codec in existence. Even with high quality FLACs.
What fooled me into thinking the phone was faulty initially was the fact that the Beyers sound fine on other devices.
So, bottom line: Apparently the V30 impedance-checking is not compatible with the Beyers using the Beyer extension. Something to do with the connection I guess, maybe some VSWR/impedance phenomenon that the V30S can't deal with.
The V30S sounds fantastic with Soundmagic E80. Also sounds fair with the included headphones (B&O?). And good with my other decent headphones (ATH-CK7), although those do not trigger HIM.
Just posting all this as info in case someone else encounters this unusual problem.

Hey, I'm not sure if anyone else is having this issue but when the dac isn't on, it's static during the music and when I'm in a call, there is static in calls on the left side. Does any one have a fix for this? I've had these headphones in my V20 and this is my first day with my V30+

Hi,
haha - and here I am and thought this phone was having hardware issues or something (does it ?) - perhaps it's just the headphones and they have an inherent flaw ?.
At least I'm getting the same weird behavior that at some points it plays fine but at others there's LOTs of (electric sounding) static on the left side.
It's actually never fully continuous for longer periods - it's more of a stuttery (multi-second) behavior for several seconds that this noise appears.
Also at first it was only via quad dac enabled - on AOSP Pie (internal LineageOS 16.0 build) it's existing no matter whether I play via Android Audio or Hi-Res Audio (USB Audio Player Pro).
And this exists on very low volume levels - there seems to be a connection that when the volume levels are raised (above 25/30% or so - I'm usually listening rather low but with this phone and hi-res - why not go higher ?)
it's way more salient and there also may be distortion involved:
An especially remarkable track in this regard is Thomas Bergersen's [from Two Steps From Hell] "Lost in Las Vegas" (around 08:30 or so towards the end, 10:14 long) towards the end - a rather electric part of the track and
when you raise the volume the output becomes rather distorted which might be connected to that "issue" and the left channel is also hissing/giving off static way more.
Perhaps audiophile folks and audio hardware experts have a better idea what this is hinting at ?
So:
not sure if it's an issue itself with the Xiaomi Hybrid Pro HD that they can't take that extra AMP (they are supposed to be low impedance and thus not require high output)
but somehow this behavior only occurs on the LG V30 - so perhaps there some kind of hardware issue ?
It seemed to have gotten better however from my impression with all those updates to the subsystems in the kernel - so it's perhaps just bad hardware design and the headphones are rather sensible
with their balanced armatures ?
Anyone else with balanced armature (BA) headphones observing a similar effect ?
I haven't had any trouble with my (dynamic driver) headphones. I wonder, have you messed around with forcing high impedance mode?

You mean high impedance adapters and such ?
Nope, only directly connecting the headphones.
And whereas before it only happened with the quad dac activated (which might provide more juice),
it now also seems to appear with the internal DAC used only (toggled via USB Audio Player Pro).
There might be a difference on how the internal and quad DAC interact or are active on recent Pie AOSP ROMs however ...
It still doesn't explain that weird behavior from the headphones themselves
Thx
I have tried it stock with no mods and it has static. Slide down the drop down and turn on the Dac and it goes away but only for music and system sounds. With calls it definitely makes noise all the time. I tried with a AOSP rom and it makes noise system wide because of the Dac. I did try my Phillips headphones and those work fine without the Dac on but I think it's a specific issue with these ear buds because I also have a 2nd pair and they also make the same noise.

Hi, I bought the nord 2 a few days ago, it's a wonderful phone but I have a problem.
The bluetooth audio quality is horrible. I don't know if it's only on my device , i have tried everything, the stock Dirac hd sound does not support bluetooth devices so the sound is flat. Also it seems like it's playing music on low bit rate. I have switched from aac to sbc there's a slight difference but still it sucks. Also changing some settings in developer settings did nothing.
I have Huawei Freebuds 4I and on every other device the sound is amazing but on the nord it's awful.
Currently I'm using wavelet eq but still the music is playing at a low bit rate. I don't wanna root my phone for viper4android so is there any other solution to this?

One plus Nord 2 is a budget phone yet not cheaper than other budget phones, yet they give a low-quality device like this. Try listening in a different Bluetooth headset.
No issue here, I have samsung galaxy buds+ TWS (aac mode) and a Marshall Mid (aptx mode) and bluetooth quality is perfect in both cases.
And for the lack of Dirac support in bluetooth mode I use the app "Poweramp Equalizer" to get some more bass in my headset
For music you can try jethdaudio player. It is extremely good.
I don't know what you are talking about I am using Realme Buds Wireless 2 on my Nord 2 and it sounds amazing and I mean it since I am picky about the audio quality with negligible delay like mine cost about 1/3rd of yours so it's probably a compability issue LDAC and AAC both work great on nord 2 ofc LDAC sounds better at the cost of more battery usage....

Maybe a faulty piece really should just visit a service centre with all those headsets and see if it can be fixed if possible test out some more headsets by asking from your friends. Also check the settings of the music app you are using it's unlikely but still possible that it's set on low

Most folks dont know this, but bluetooth is a modern NAME for 'A' software version of hardware based tech capable of transmitting 240v AC through the air.
Tunguska anyone? That was the test, and the origional copywright is owned by TESLA.
Bluetooth, was designed to do the same, it's designed for AC current, explaining why bluetooth digital audio is the WORST sound ever invented.
Blutooth sounds so crap due to the following:
1: The inventors of digital audio decided to remove EVERY frequency the human ear cant hear. (according to who?)
2: They are now removing the lower base frequencies that we COULD hear, if we had say speaker's like my set of BW speaker's used by the BBC in the 60's and 70's, which can produce EVERY frequency. To make these speakers today is £14.000 PER speaker.
3: By removing all lower frequencies, they removed what is known in music, as the BODY of sound. They started this with digital techno, aka goa trance. I stopped buying musical digital instruments just because of this. If you take a 90's version of say 'Rising High's Church of Extacy' ( The tune that officially killed rock and roll due to it's pure analogue sound quality, hardness, and the deepest bass ) then play it through bluetooth, all you hear is tsstsstsstss, because the tweaters you think are great sounding speakers literally cant play anything under the highhat, without ECHO to fake the BASS.
If it's audio QUALITY you want, DROP bluetooth. Simple.
Another note:
As a dj of over 40 years in the undergound dance music scene, the one thing I cant understand is why I now have no CHOICE but to buy headphones for djing with a bluetooth mic built in! This allows whoever is spying on what we SAY to record my tune or live mix before I leave the gig, and claim it as their own. Try buying decent ANALOGUE headfones for djing.
Final note.
Nfc: the modern day verion of blutooth. Interfere's with bluetooth audio in that the AC current also has it's own magnetic field, which can, like binaural beats, interfere with bluetooth. Most fones use bluetooth AND Nfc. nae luck.
I personnaly know the best hacker in Scotland. 12 letters after his name in computer sciences...! He wrote the bluetooth app the gov called tap n trace, and he sold it to them for £30.000, they added Nfc (Near field Communication) and got most people in the world to install it in their fone. NIce one Gi88's!

I am using my Sony WH-1000XM3 and it supports LDAC. The audio quality is great with support for equaliser. The only way to get LDAC was change the mode from connection stability to sound quality mode in sony headphone app. By default, it supports SBC. Pls check your headphone's app and also check if your headphone supports relevant codec.hope this helps.
I had a similar issue with my Nord 2 and my Libratone Too BT speaker, sound was horrible, like an old cassette player. The speaker only supports the SBC codec, I think.
I was able to fix the sound quality by enabling developer options and switching to AVRCP 1.6 and MAP 1.4 there.
