It is better to make a thread about the bluetooth wakelock...because it's a more common problem...thank you.
[G2 General] Hid3rs:
I'm pretty sure everyone has this sound issue. Just because some can't hear it, it doesn't mean it's not there.

BT "wakelock" doesn't seem to drain battery after all.
[G2 General] gbssengo:
Just FYI for all, I have the D803 (Canadian) variant with a Bose QC15. I had the left ear noise even on 4.2.2. We didn't get KitKat yet and I get it on every song change.. Super annoying.
[G2 General] Kiwi_Dude:
In reply to the above... No hiss or crackle here. Taiwan D802 32GB (4.4.2). Tested using stock Quadbeats and Logitech UE 200.
[G2 General] sanke1:
Only Mahdi ROM has comparable sound quality to stock LG roms.
[G2 General] slaav:
I can confirm that after KK update (official through LG PC Suite) I'm hearing massive noises while trying to listening to the music.

I'm using Sennheiser HD380Pro headphones (54Ohm) - at home I'll check with 300Ohm (HD600)

My phone: international D802 bought in Poland. HW version: Rev1.0 (3845#*802# ->Settings->Version info->HW Version)

I've already reported this issue to LG Poland - waiting for an answer (if any)
[G2 General] abo_mara7:
I've just updated to KK OTA (AHKGWH) and I tried to produce this bug but I couldn't. So, everything is OK with me.
[G2 General] lukeap69:
Good for you then.
[G2 General] giorgosfil13:
Since I'm an Audiophile, I won't be upgrading to kitkat until LG fixes this issue.
[G2 General] walidhiphop:
By the way...and sorry for the off topic...i found that the bluetooth wakelock is just the "Android OS" and it is a bug that has it named to "bluetooth"....so don't worry it's all ok..
[G2 General] hamad138:
Ita not that bad on lg ear pods.

But still needs to be fixed asap
[G2 General] fallenwout:
Smart choice. Lg benelux has no knowledge of this problem. The official support call says they will do nothing because they don't know about it. Which is major bs because i just told them no?

It seems I have a german model bought in Belgium. So belgium will not help me, cuz they think i have an unofficial update... I have a belgium invoice with belgan warranty.

Amateurs!
[G2 General] sidde:
I can confirm that i have this bug too with every other corded headset/earphones/aux but the iPhone earplugs, none distorsion whatsoever in them.

My Sennheiser PC360 gamingheadset was worst of all in reproducing this noise.

Luckily they got the A2DP bluetooth soundquality issue fixed with 4.4.2 because i mainly use my Plantronics BackBeat Go 2 bluetooth plugs and there is no distorsion there. :good:
[G2 General] maydayind:
Weird.. I had som noise when running jb 80210a-eur-xx

Running 80220b now and got no audio distortions ore noice.

Maby it's the kernel. I run Savocas moded. On jb I run dorimax
[G2 General] bazon:
It is definetly depending on the headphones you connect the LG G2 to.

In a german android forum, we found that most headphones which have no or only slight noises, have an impedance of about 16 Ohm.

http://www.android-hilfe.de/lg-d802-g2-forum/547776-rauschen-seit-kitkat-update-9.html
[G2 General] fallenwout:
What if told you i didn't have any noise with my high fidelty headset on 4.2.2 but have it with the same headset very clear in 4.4.2?

It could be true what you say but the type of headset is defently not the cause.
[G2 General] bazon:
I didn't meant to say anything else. Of course it's only happening in 4.4.2, that's what we are talking about here all the time.

The 4.4.2 update is the cause, but the size of the impact also depends on the headphones you are using.

I hope it's clear now.
[G2 General] Frutek:
In my case I heard the noise on 4.2.2 also. But it was like 10% of what is on 4.4.2 with my on go headphones (hifiman re262). Those don't pick up electronic noise easily. I'll try to mess with mixer_paths maybe it has something to do with this noise...
[G2 General] tlkl:
In my case, in jb whith akg 451 work perfect, but in kk have the problem, i m sure that the problem is kk

Enviado desde mi Nexus 7 mediante Tapatalk
[G2 General] slaav:
Well, that doesn't match my observations. I can hear a lot of noise on my 300Ohm HD600s. I agree that still less than on a 54Ohm ones, but that is obvious.

BTW, don't you think, that KK is in general louder than GB? Maybe they wanted to address low level output complains and they screwed something up? I personally would prefer to have quieter signal but with better quality.
[G2 General] Frutek:
Yeah it is definitely louder. There is problem with N5 and G2 with the high noise/distortion on high gain ( you can read about it on anandtech here ). That's why they are set to quite low gain.
[G2 General] :
then those experiencing it can try editing mixerpaths.xml or the snd_soc_msm_Taiko

there are some mentions of gains there :)

at own risk

send from the jungle
[G2 General] Frutek:
I have tried. Still no effect when I lowered gains... rolling back to JB for this time...
[G2 General] amno1970:
It works

No need for reboot.

Just enter hidden menu and do the audio loop back test.

It takes effect immediately and will be there until next reboot.

Is there a possibility to write a script with that tasks to run at boot time?

Regards.
[G2 General] charlesip:
Which audio player am I suppose to get the problem. Just got the KK update for my HK D802 last night and did a quick test in poweramp with my ultimate ears iems and didn't notice it
[G2 General] Frutek:
It happens globally not only in music players. Every time you hear sound in headphones there is that noise (left channel) . Either you are one of the lucky ones that doesn't have that or you have headphones that aren't sensitive to this noise :)
[G2 General] farhanito:
Has anybody tried to brought this issue to media?

Maybe if Android Headlines or Android Police, etc. can confirm this, they can push LG even more ?
[G2 General] charlesip:
I am listening on UE triple fi. Really no unusual sounds on the left channel all day
[G2 General] fallenwout:
Lg belgium say they know the issue and will be fixed within weeks.

Although they claim the problem only exists/originates from their own music player.
[G2 General] Gnarfsan:
I doubt it. The AOSP kitkat ROMs here don't have this issue as far as I have noticed.
[G2 General] kennguy:
I'm using 32GB and I would like to try this firmware but I do not know if the battery life is as good as 4.2.2? :(
[G2 General] walidhiphop:
Don't worry mate...the battery is the same as before if not better...just let it settle a few days after flash...
[G2 General] ephumuris:
Has anyone gotten any further with investigating this? My replacement handset is out for delivery tomorrow after my screen issue...will be more careful flashing kernels in future!

Can someone share this story with a big site like Engadget or something for some more exposure?!
[G2 General] 3rdeyer:
I just flashed pardus kitkat rom and so far my sounds issues on KK seem to be gone. I have had KK installed before(vodafone version) and had the very annoying hissing/crackling sound. I am using shure 215 in-ear phones and I can now enjoy my music both at low and high volume levels on KK. System sounds also work as it should.

Perhaps you guys can give it a try as well, the rom keeps the custom recovery intact so switching back to 4.2.2 is not that much of a hassle this time around.
[G2 General] playerPA:
It did not work for me, hissing sound was even more noticable. I restored back to CloudyStock 1.1
[G2 General] superbonto:
reporting in.

D802 using v20b europe open, using sennheiser CX300 II

i'm not sure if the noise is there or just merely a suggestion since i read a lot of people complaining about it.

I can't hear anything in D802 SEA KK, fwiw.

[G2 General] metalboy94:
Dunno if it's been posted before but the bug is more obvious on low impedance headphones. If someone could take a look inside snd_soc_msm_Taiko and figure out what's new since 4.2.2 we might be able to figure it out. FWIW there seems to be a new parameter possibly related to dynamic compression.
[G2 General] :
did you try reboot after changing, cause they dont get picked up hot. Can you share them unaltered I can do a diff see if I can find something

[G2 General] noris08:
i saw a lot of people saying that they don't have the annoying hiss. is it possible that some phones will be affected and some don't?

can we find a pattern for the phone affected?

with 4.2.2 i had perfect sound. i flashed 4 different kk roms (romania open, germany open, singapore open and hong kong open) and all of them have the sound issue.

my model is 802 international with 32 gb.

it came with hong kong jb soft, but i switched to romania jb with no issues.

i did the update to kk using lg mobile support and a method from here because i don't have an official ota yet

maybe people affected will find something similar on their phones and behaviour anw we can figure why just some phones seems to be affected.
[G2 General] Anilexis:
I have D802 and only installed official updates. The sound on 4.2.2 was good with no problems on all tested headphones. With 4.4.2 OTA I have the problems described in OP post with Philips Stretch (32Ohm). But there are no problems with Sennheiser CX680 (16Ohm) headphones. Strange.
[G2 General] sidde:
That's strange because i had the noise with my CX680, i even tried with and without the volume adjusting cord. :confused:
[G2 General] Anilexis:
I tried them without cord, cause I don't have it with me. All clean, not like with Philips one which was horrible.
[G2 General] gokturk_1976:
I can't hear any sound deformation,hiss or crackling on my D802 international 16GB. I'm using D80220b Netherlands 4.4.2 stock rom and Sennheiser CX275
[G2 General] Anilexis:
I tried Sennheiser HD598 (50 Ohm) - a lot of hiss. Still no hiss with CX680. Very strange.
[G2 General] noris08:
same thing happened to me:confused:. fingers crossed to stay this way

me happy now:D
[G2 General] slaav:
Any changes in the meantime? Any applications installed/removed? Reboots?
[G2 General] noris08:
i reflashed the 4.4.2 rom because i was doing some tests, but i still had the hiss after that.

then i had a few calls, red a few emails, a little tapatalk and nothing else i can remember. maybe 1 or 2 reboots

there is no evident reason
[G2 General] farhanito:
WTH.. I think my left channel "healed" itself too..

No more hissing with system/notification sounds. But noise on music shifts to right channel now..

Weird.
[G2 General] Frutek:
Yeah ofc I did reboot after changes :) I rolled back to JB. I'm going to check if I still got the mixer files when I get home.
[G2 General] noris08:
Me unhappy again! :mad:

I rebooted the phone and the annoying hiss is back again.

I listened for 2 hours of perfect music but no more. What is wrong with this update?

[G2 General] BigBoyPL:
Guyz do 1Hz generator test. You should't hear anything but you will hear strange sound on left channel ;]

I noticed when I was using service menu that something is wrong if you do loopback test and repeatedly insert and pull headphones jack. You will hear sound on left channel in headphones and on phone speaker! No sound on right channel on headphones ;]
[G2 General] playerPA:
The thing is that annoying sound goes away after some period of use. Bad thing though is that it comes back everytime you reboot your device. Bottom line is, if you dont hear it reset your phone and you will know whats the problem everyone is complaining abou ;)
[G2 General] ephumuris:
I've got to root and sort out my replacement handset tonight. I'll pull the /etc folder seeing as nobody responded to my request for it and then update to KitKat and see what I can figure out.
[G2 General] :
guess NL is out now, dont have this issue on stock phones. I guess guys with this problem and root.

download winmerge, and do a comparison. Might need to rename file in order to open it.

then search for headphones and check the volumes, min max. mostlikely the mixerpaths will be enought.

then again one guy already did try so it may be for naught.

send from the jungle
[G2 General] Frutek:
okay I got mixer_paths.xml before gain tweaks - View attachment mixer_paths.txt
[G2 General] :
ok I made a diff between jb and kitkat soc_msm_taiko. Saw no sigbificant differences other then volumes are lower, and some changes to speaker. These I think cannot account to the issue.

So looking at the mixer files becomes important.

will checkin later.

meantime someone can send me the snd file from the kitkat that has the issue.

ok checked the mixer paths, from tinkering mahdis one and cm11 they can be unstable.

many changes, for those with issue, and didnt have it on custom roms. Backup mixer path and snd file. try these from cm11 rom. Put them in right folder, and change permissions so they reflect original files. reboot and check if issues persist. If they dont. its one of the changes. If they do its something else.

all at own risk. cause I have no idea if it can break anything.

send from the jungle
[G2 General] Floodland:
Just reporting... The phone does not complete the boot after updating the files. Tried wiping both caches, rebooting and the phone hung after optimizing apps with the legend "Starting apps". I did not hear the startup sound either. I think CM11 files are not LG kit kat compatible :(

... Good try anyway

Flashing CloudyPro one more time...
[G2 General] phobius87:
I can confirm this hissing sound in left earphone bug on my LG G2 D802. It's noticable on any sound, even system sounds. The hiss can be heard for about 10 seconds, before it goes away. If I play music and stop it, or if some other sound activates, the hiss is present for another 10 seconds or so.

So far I hate this KitKat update. My battery drains almost twice as fast and now this hiss bug. LG should react fast. Is there somewhere I can adress those bugs directly to LG. I know there is my local LG support and I allready talked to them, but I know they aren't going to do anything about it.
[G2 General] Frutek:
I flashed modded files with a rom package. Editing those files from the phone made my device bootloop too.

I modded original file based on mahdi source with a little bit of my tweaks but it didn't work for me :|
[G2 General] :
I guess we can strike that off the list. I am all out of clues, I would return stock completely and check store if they have a replacement as its still under warrantee.

better yet check instore with your headset if it occurs on one of their units. Providing they have them updated to kitkat ofcourse.

[G2 General] Blumdum:

The loopback test thing completely fixes it for me until a reboot. It would be great if we could figure out what commands the loopback test runs and get it to run on a reboot. I only did the first loopback test too.
[G2 General] joeyvanhummel:
Same here

Dutch unbranded unit, d802 on d80220b-EUR-xx

Never noticed this sound before. I use my Sennheiser HD429 as daily headphones so it's not them.

Weirdly, I hear the hissing/crackling on my right earcup instead of the oft-reported left, but it's generally really bad. AS if it's picking up a whole lot of interference (both left and right) and the right earcup seems to be clipping badly.

Connected to my PC the headphone's fine again.
[G2 General] Chris_n00bz:
D80220a-ESA-xx here and I didn't have any issue of hissing using both LG Music Player and Play Music. My daily earphones is a cheap one from Senheisser. In my local G2 forum, some people are also complaining about the hiss. Is it possible that only phone that had been rooted has this bug? Mine is unrooted
[G2 General] shudoha:
no ... even after a clean install of kdz.

without root. the problem is still present
[G2 General] ephumuris:
Definitely present on unrooted units too.
[G2 General] noris08:
how do you do the loopback test?

thank you!
[G2 General] shudoha:
Ok so unplug your headphones. Click reboot on your device. When your device will reboot plug the headphones. Go to dial keypad. Look about what sound keypad keys like 2,5,0,#. Delete all what you typed. Type in dial 3845#*802#, it will show Hidden Menu.

Click on ELT Test, switch to Manual Mode and click Test Start.

With pluged headphones Click on Audio Loopback to mark it and than click Test Start. Say something or blow breathe to all of your microphones (1st on top right, 2nd on bottom left near jack and 3rd on your headphones). Stay on test more than 20 seconds with saying or blowing breathe.

Click STOP, than do same with Audio loopback Mic1 Mic2 and Mic3 ( start test and blow breathe).

After all loopback test leave service menu and play some music.
[G2 General] :
you can check snd\mixer paths, loopback is routed differently, I saw that, try adapting regular for that loopback. maybe it can be done

maybe some variable is set and unset when rebooting, then that variable can be set for regular, interesting

I connect universal to my pc w/ usb and want to rename/delete files in windows directory. It told me some pemmisson error. How can I do such things?

I can create new folds in the directory.

Seems a new bie question. thanks in advance.
[JASJAR, XDA Exec, MDA Pro Software Upgrading] vijay555:
Files in the windows folder are generally ROM files, so you can't really delete them, they'll just come back from ROM when you reset.

So - you can use the old technique, normally, of using something like gsfinder, rename the file you want to change, eg ctlpnl.exe to ctlpnl.orig, then copy a new file into the windows folder and rename it to ctlpnl.exe.

That works well with some files, but not all.

To do some heavy duty modding, you would have to make your own rom. Find RomTools by Mamaich.

V
[JASJAR, XDA Exec, MDA Pro Software Upgrading] davidpenn:
But I can't rename any files belong to original rom. When I use GSfinder to rename the file, it also reported "Cannot rename file.". I checked the property of the file, it has "rom" property and the checkbox of "rom" property is gray.

How?

[JASJAR, XDA Exec, MDA Pro Software Upgrading] vijay555:
As you say, if it's a proper ROM file that wants to be stubborn (it may already be in use. Try closing the app using a good task manager first) then your other option could just be burning a new rom.

Why do you need to rename it?

[JASJAR, XDA Exec, MDA Pro Software Upgrading] davidpenn:
