Yeah it has been a long time since I listened to music on my G2. I can't stand the noise.
[G2 General] buenarc:
might have manufacturing defect though..
[G2 General] joshyboylee:
I definitely have the problem, noticed it the day after updating to KitKat. Tried Tweakbox fix and it's slightly improved but still unbearable. Can only just hear it with stock headphones, more obvious with PMX60 and ridiculously bad with ATH-M50 .

Is there still no fix available? It's pretty bad for a phone touted for its audio capabilities to be unable to listen to music at all.

D80220a, Build KOT49I, Software HKG-XX.
[G2 General] yaniv30:
I still don't get it.

Honestly i don't know how LG can live with this bug. Imagine that anyone who wants to buy an LG G2 now will know that he can't listen to music via headphones.. This is absurd
[G2 General] :
please go and complain to lg so they know your phone version and software has an issue. :)

if you are willing to break warrantee, going back to jb, root, twrp recovery, d802 20c zip with recovery in it. mahdi beta 2, patch v5 should do the trick. if not flash something after. forgot where to find it. pm me and it should be pretty nice
[G2 General] buenarc:
LG warranty may be the answer for this. you should have no trouble at this phone.
[G2 General] bruce2728:
FIX

I've fixed this bug if anybody is interested.

I have built a zip containing a kernel I put together which is the stock d802 kernel built with linaro using -o3 compiler flags. All i have added is some code to get DSP Manager working.

I have included DSP Manager and the necessary libs in the zip which can be found here.

I have a D802 on 3 in the UK and it works fine for me, just flash in recovery and enjoy.

As always, I accept no responsibility for loss or damage.
[G2 General] ephumuris:
The legendary Bruce!
[G2 General] Norside:
FIXED!

After lg's latest update the hiss is fixed completly!

For anyone with d802 that is rooted, you can flash cloudyfa's knock code kernel (look in his cloudyflex thread and you should use his flex or pro rom) to fix the hiss bug completly:D

Edit: You can also use dorimanx 4.3.1 to fix this issue (or any kernel that is based on lg's latest kernel source)

Now there is no downside with kitkat versus jb for me ;)
[G2 General] bruce2728:
I didn't. Know lg had fixed it already.

I've only had the phone since Wednesday, if i got it earlier you would have had a fix when the bug first appeared.

This replaces the stock sound effects with cyanogenmods dsp manager.
[G2 General] ephumuris:
Bruce have you any plans for development on this device? I remember using CM by you on my sensation xe I think it was...
[G2 General] bruce2728:
Yes, i was the one that bought jb to the sensation.

I will be working on the g2, maybe a kernel, but i might look into optimizing the stock rom a bit too.
[G2 General] Norside:
Awesome!! We need all developers for our g2, so I am looking foreward to more from you :D

Hi, are you talking about official lg's update or a fix via custom rom installation?

[G2 General] platiNa:
Update just came in for me as well. Phone is bone-stock, bought from Amazon.de. If your phone doesnt report an update, check for updates manually.
[G2 General] Priit.U:
Bought my G2 a few days ago and had the same audio hissing problems with the KitKat update. Got the update today as well, but sadly for me the problem still exists. The hissing doesn't appear for some amount of seconds AFTER pausing any audio, so they seem to have fixed something. But i still get hissing and buzzing on the background when playing music. This is more noticeable when playing some quiet moment. Tested with my Sennheiser HD558 and the ones that came with the phone. If you guys test your audio after the update, listen very carefully to what's coming from the headphones. That said, they seem to have fixed the problem a bit, but it's still VERY much existent.

This, and the fact that my G2 has very noticeable digitizer lines on the screen (yes, even when the screen is working in a darker room) makes me very disappointed with the phone in general. Probably gonna see what the warranty provider in my country is going to tell me.
[G2 General] Trixanity:
No OTA update for me at least. D802 on the B firmware (never got C either).

[G2 General] Luk@s:
Unfortunately you are wrong. It's better, but it's not perfect. I tried V20b with bug - terrible hissing, after that V20D. The hiss is very quiet, but when listening to music (you can hear it well on quiet songs) the left channel still has something like distortion. Next V20B Vodafone - identical like V20D. Finally I flashed JB V10E - perfect without hissing, noise and distortion. I'm still waiting for 100% solution or maybe you know such unofficial method?

Tested on Logitech UE700, Beyerdynamic DTX501p. Wipe was done after every flashing.

I take it back. It is not gone entirely. With normal headsets you hardly notice it, but with high fidelity headset you notice it is still there. Left channel noise, dammit LG! 80220d

[G2 General] parisstc:
I am using the same headphones that had hissing with 20b and now I cant hear it,

I cant know if the problem persists with other kind if headphones, maybe it has to do with the khz range of each kind?
[G2 General] johndoe-xda:
I doubt it, because I've tried with both crappy earbuds and good headphones.

To those who have tried the 20d firmware: is both the hiss and the electronic noise/crackling (especially in the left channel) gone?
[G2 General] :
music in general is good, however some distortion still there and some crackling. It is however pretty good, it stopped me from returning to jb :)
[G2 General] mannequin:
even the slightest disruptuon to the sound means it's still no good and they need to go back to the drawing board, considering JB is silent as a tank.

v20d Fixes hissing, not distortion (low frequencies sound somewhat overmodulated) as far as I can hear. At least, if there is still hissing, the signal/noise ratio has now been dramatically improved.

Hi,

I've downloaded an OTA update, I guess it is the one it's under discussion here. The problem is that I'm a newbie :crying:

I have a rooted D802, with TWRP (got through AutoRec)

The problem is that, when trying to update, my phone always reboots into recovery (TWRP), so I never get the phone "running" correctly.

I found how to avoid this boot-loop, using this: http://xdaforums.com/showthread.php?t=2451696

It works fine... but I still don't know how to apply the OTA update. Maybe do I need to change TWRP for stock recovery?

In that case... how the hell is that?!? I cannot find a "simple" guide to do it. Remember.. I am (a bit) newbie

Please help!
[G2 General] :
dont stress, first rule of ota, never do on custom recovery. If you have custom recovery get back to non custum. How?

via lg mobile support tool and hope none of your stuff is deleted. Via recovery update in tool.

maybe backup your twrp backup also, always nice to have backed up off phone, to recover that you will have to get back to the same rom most likely that is on when made recovery.

or, via the stickied in general section, way to get back to recovery
[G2 General] antomontex:
THANKS Bachera. I've tried with a Windows 8, but the program looks very bizarre. Tomorrow I'll try with XP.

Anyway, what exactly will perform this method? Flash a new stock ROM? Change only the recovery by a stock recovery?

I also have Xposed, but I've disabled it as far as it seems that also break the OTAs.

Do you know if after updating (if I get it...), I will need to root again? Will be valid any current method?
[G2 General] bbsdummy:

You mean low impedance earpieces? I've never seen any high impedance earpieces (more than 32 ohms).

No. I've badly explained... My AKG K430 and DENON AH-D 1100 are both 32 ohm, and sound is horrible, compared to my in-ear Sennheiser CX 300II that are 16 ohm, with a clean sound.

[G2 General] hd1080ts:
I have the left channel noise bug.

D802 16GB sim free bought direct from Amazon UK on May 8th (2 days ago). on stock Kit Kat.

On first updating to Kit Kat had terrible noise on both channels, after the small apps update that was fixed and now have the left channel noise bug instead.

At first I thought it was a Google Music streaming issue, but playing ALAC files in PowerAmp had the issue, then suspected my Shure SE435 IEMs had a failing driver, but they are fine on everything else.

Just confirm that is this a software bug not a hardware issue?

can sb. help me? :(
[G2 General] xlr8me:
I think the hiss was there prior to rooting. I doubt twrp would cause the hiss to return.

I am rooted but on jelly bean so it's not ioroot causing the hiss as I am hiss free .

To return to jelly bean follow the sticky.

Good luck.
[G2 General] ephumuris:
It would return if you used autorec or something similar as the kernel would be replaced... At least I think so. Cloudyfa has a kernel you could flash I think it works with stock and has no hiss.

Thanks for the link. The kernel solved the problem partially. I'm mean the hissing is slightly noticeable now, but it is still there.
[G2 General] avesopi:
That's strange, the kernel is based on the official 20d (Knock-Code) update for the G2, and after that update the noise was gone at all G2´s.

After flashing ive tried 3 different headsets (steelseries, apple & House of Marley) and i can´t hear the hissing anymore.

is there a way to fix this that doesn't require root and all that jazz?

I know I'm posting on a forum where this is pretty common

So I'm not trying that again?

I heard that firmware version 20D fixes this? will I be able to update this ota?

Sorry I'm a bit of a noob :(
[G2 General] Drako12:
The problem im having is close to this, but might not be the same, can anyone help me with it?

When im driving and i call someone the person on the other side of the line always complains about a crackling/hissing sound on the background, also, it only happens when im driving, if im stuck in traffic and my car stops, the noise stops until i begin to accelerate again.

my baseband was m8974a-aaaanazm-1.0.190036

i changed to m8974a-aaaanazm-1.0.190084 , i still didnt test because test conditions are not easy (i have to be driving, im at work right now).

But what else could it be? If this doesnt work i will change roms, im using slimkat at the moment.

[G2 General] famanfwppc:
VERY IMPORTANT. PLEASE READ!

Hi all! I'm on 20a stock rom and 4.7 Dorimanx kernel moreover i'm playing with FauxSound App attempting to resolve this issue.

Playing with FauxSound app I discovered I can magnify many times my audio problem without be able to reduce it to extinction.

There's something really wrong with LG G2 audio and hearing music from headphones.

What I discovered is that any music file recorded at low level volumes can be used to drive out the worse of this issue.

and I can describe it like a low volume dynamic amplification or even better an audio normalizer (that lowers even excessively high volumes) in place that tries to let you dinamically hear minimum volumes (and you can understand this because it raises a lot recorded environment noise)

This seems a phone call function in place that makes sense because you want to hear any caller in any environment condition so you can hear him if he's moving near/far from his microphone and volume should ever seem the same to you and be audible everytime.

Obviously when you are listening for music this is a totally unwanted feature.

Please spread this information specially if are in contact with anyone able to fix this, and because I'm not infallible, to confirm that my test is repeatable and conclusion is right.

I never read about something like my description so sorry if this isn't any new for someone.

Hope this can be fixed soon.

What I've used to test: "Say Something" (A Great Big World) mp3 file, cause it has fantastic intro piano envelope that (as said) drives out the worse of this issue, if you have also the ability to play with audio gains like with Faux app, It can be used to lower even normal volume song and raise up a lot of noise.

Thank you

EDIT: Even if you are on 20d or think the problem is solved for you, please try to play the above song I suggested "Say Something" even from Youtube and try to catch the bad in first fifty seconds and at the end (20 second from the end) it's impossible to not notice it if it's still there. Please report your findings.
[G2 General] fallenwout:
I've already reported it back to LG that it is not gone on 20d firmware, just reduced and weaker. Haven't heard anything from them since.

I don't think they will fix this. They would have already if they could (or want to).

I really don't understand as this is so bad for sales. I, for one, would never buy a new smartphone that has audio playback like this.

I hope this isnt planned obsolescence.

Latest released Indian (ESA V20B) update does not have this issue. Thank god.
[G2 General] famanfwppc:
I would like to remind everyone, if possible, to carry out the test with the song that I have indicated, as with any other song mastered with average volume will have much more difficulty appreciating the flaw. That said, if you say it's no more there, I believe you all and thank you.

EDIT: further testing: if you have a bluetooth headset listen to the same song with this and with the supplied headphones or listen to it on headphones on the PC and then on the phone with the headphones supplied.

LG Support of little help

I purchased my phone in NZ about a month ago and have been having the same issues after upgrading to 4.4.2. (D802T20b-AUS-XX)

It's not really noticeable on LG's Quadbeats but quite obvious on my Shure 535's and Logitech UE 9000.

I decided to follow the official channels by sending LG an e-mail only to find that you can only send them information via a submission on their webpage which is capped at 1,000 characters. So i did this and when I went to submit it, the website came back with that fact that it was undergoing maintenance and my whole message was lost which was annoying to say the least.

Anyway, I gave them a call on their 0800 number and spoke to one of the 'support team' who kept telling me I needed to reset my phone and then perform a system recovery. I kept telling him that the issue was the software update and not a setting on the phone. I guess he got sick of me because he said quickly blurted out "HaveanicedaythankyouforcallingLG." and hung up.

Has anyone else in Australia/New Zealand had any luck escalating this issue with LG? I would rather avoid rooting my phone to resolve the issue as I'm concerned about bricking it.

Cheers.

Just to let you know, this happens with 4.2.2 on my Nexus 4, so it must be Android related. In my old car, I'd plug the audio jack into the phone to listen to Spotify when driving and the left speakers would always have this noticable high pitched noise.
