No need for the mic tests it works with just the first loopback test...

Asked LGUK Twitter again about the bug and what a surprise...

"Hi David, Sorry but I don't have exact technical details of the update(s) for G2."

A fix probably isn't even coming.
[G2 General] :
lol, the file doesnt change, within it contains the mapping and volume sets when doing stuff. headpones, microphone etc. So when running test something might be set that isnt when not running test. how to check whats set I dont know.

I am not sure what COMP1 does, but its set to zero on loop. it set to 1 on headphones. at own risk but set it to 0 on headphones in mixer file, save, check permissions of file, reboot and report :)

I do think that because some dont have it something else could be at play other then settings.

[G2 General] kevinzzz:
same problem here

I have that issue on BOTH of my Sennheiser's earcups.

With LG's earphone I only have it on one earcup and the noise is not as loud.

I am a french user with that phone:

LG-D802

I'll probably wait a few days before downgrading the phone back to Jelly Bean. I'm not keen on waiting for LG...
[G2 General] shudoha:
kevin tu reboot souvent ton telephone ou comme moi tu le laisses allumer tout le temps .?

car si c'est le cas il existe une solution qui marche et qui prends que 20 seconde . que tu peux méme refaire a chaque redemarrage si tu veux

pour garder kitkat en attendant qu'il trouve une solution au bruit je la teste depuis ce matin 4 h de musique et le son tu l'entends plus .

j'ai rebooter il est revenu et j'ai fais la méme manip . mais au final tant que je reboot pas . ben la manip fonctionne nikel

donc si ca t'interesse dis le moi

lol im french men and kevin too ...
[G2 General] Frutek:
Use PM then...

Back on the topic... When you guys use that service menu method does noise in left headpiece completely disappears? In my case I can still hear silent hissing but no radio static noise. Also this hissing seems to get louder when the music you output have a lot of low frequency sounds.
[G2 General] :
Same here, hissing is still here. But without static it is better than nothing

same problem with files .... bad

thx
[G2 General] Swetnes:
Would it be possible to take the baseband and modem partitions for your region and flash them with the D800 rom? I am new to this phone, but on my previous phone the LG Nitro HD, the baseband and firmware (modem) were just separate .img files that could be flashed along with the system partition. This would, in theory at least, eliminate the bug in the D802 Rom??
[G2 General] daniel_pt:
I have absolutely no issues at all with the sound... I'm trying this hiss thing with both LG headset and an HTC headset. Sound is normal with both...

I have this kk version..... dunno why I have a SEA rom as I'm in Europe and bought the phone in Europe! Probably it came from SE Asia...
[G2 General] 3rdeyer:
Since I had this problem on the vodafone KK rom, but no longer on my current KK rom ( that is identical, except no bloatware), it has to be some setting that is creating the sound problems. My guess is that it has to do with system sounds. When I flashed my latest (for me working) rom I did not yet connect anything to the headphone jacket and I disabled all sounds located at settings - > Touch feedback & system.

When pressing the volume rockers the volume sliders are still colored blue and thus active. The strange about his however is that these system sounds only work when there is nothing connected to the headphone jacket, and thus they are only played through the phone speaker. When a headphone is connected all such sounds are muted and only the music that is running can be heard.

Perhaps you guys can disable the touch feedback and system sounds in the settings menu and see if it resolves any issues.
[G2 General] Frutek:
I disable touch feedback and system sounds ASAP I boot into new room :) Didn't work for me apparently. Which D802 you got ( region and memory) and what's your current rom?
[G2 General] 3rdeyer:
I have got the Pendroz KK rom and I am on a D802 Int. Others on that rom reported they still have the issue so that's why it needs to be some other (combination) of settings..
[G2 General] flickyamom:
I'm hearing this problems one Cloudy stock 1.1 D802..I did not encounter it on cloudy pro II. It's:mad: REALLY irritating. I'm going to try flashing it again, see what happens.

Update: Flashed cloudy pro II again and encountered the bug again.. Looks like it's chronic.
[G2 General] Frutek:
Do you have SEA 32GB international D802?
[G2 General] flickyamom:
Yeah I have it. Why?
[G2 General] daniel_pt:
It's odd... I also have a SEA 32GB internacional rom and don't have any hiss... although I have the stock kk 20a
[G2 General] flickyamom:
Hmm.. right now I'm not using SEA... I'm using KOT49I.D80220a from cloudy stock 1.1.
[G2 General] Frutek:
You can check your original ROM country code on the g2 box. Flashing different ROM may overwrite it.
[G2 General] ephumuris:
I don't know about you guys but this phone is still my favourite device I've had out of MANY android phones.

The loopback test is an inconvenience but audio is listenable again with it and that's the only thing that was bothering me.
[G2 General] shudoha:
yes 20 scd for the loopback . if you do not turn off your phone

or 20 scd if you turn on ... it is not boring, time to find a permanent solution

its a great alternative
[G2 General] Looserke:
Marek Tupa make a video of the audio bug:

you can find it if you search in youtube for : lg g2 headphones problems

sry i cant link it to the forum yet, need another 9 posts more... :(
[G2 General] shudoha:
in this video . there is solution?
[G2 General] Frutek:
No. It's just the recording of the music playing with this noise.

http://www.youtube.com/watch?v=Qge3b6EVgNQ
[G2 General] shudoha:
good news .

I talked about the loopback on the site

to optimus and he told me he was working on for the next version of rom

Lg g2 pro Port

its a good room with a lot of good option
[G2 General] Frutek:
But audio loop back doesn't fix the sound problem completely. There's still hiss in the headphones headphones. It must be related to kernel as the sound files (taiko and mixers) change next to nothing about hiss & static. The fact that good devs are working on fixing LG devs mess is amazing tho. I can't imagine waiting months for fix like in Windows mobile...
[G2 General] shudoha:
yes but optimus

this is a good dev

loopback even if it does not completely solve the problem

it can put on the voice

and then so far the devs have created things

or patches or even rom much better than the one we propose

or even kernels quality
[G2 General] Dorly:
I have got the same problem, I have an LG G2 imported from singapore with Kitkat updated OTA (D80220A-SEA-XX) . I am using Audio Technica ATH-ES55. I have done a loop back but it solved only the problem of hissing after doing pause :( .

There is still this problem while playing music, but unlike ephumuris, the problem is most noticeable on the right side in my case.
[G2 General] marek_poland:
How about the problem in v20b? Is there still this bug? I can update from v10e to v20b but I'm not sure if the problem has gone

[G2 General] shaarky:
I hear the noise as well,actually noise and cracking.... annoying :(
[G2 General] B!GBOY:
Wow after loopback test its much much better!

does any one know what does it do that affect this problem? i mean its a test! how does it affect this problem?
[G2 General] Floodland:
Not really sure, we know it is not DSP related (with Viper Audio DSP you hear the same noises). The issue is more noticeable with good headphones, impedance related. With stock earbuds you may not notice it.

I suspect that is the reason such gross bug slipped out of the LG labs (if they tested 5s with stock earbuds they may not have perceived the problem).

For now, tested solutions did not work. I guess we will need to wait until the genius at LG wake up and provide a working solution...
[G2 General] joeyvanhummel:
10e Doesn't have the problem to begin with.

Anyway, yes, it's in 20b, so if you're still on 4.2.2, stay there if you value good audio output.
[G2 General] farhanito:
This issue affects audio jack output only. Not Bluetooth or USB output (with external DAC).
[G2 General] SKyRocKeting727:

[G2 General] lukeap69:
There is also a problem with the USB audio output in 4.4.2. It is not supported natively, i.e. when using music players such as the stock player, Poweramp or Neutron. It only works with USB Audio Player/Recorder Pro. In 4.2.2, USB audio output is supported natively. That is why I am back to using 4.2.2.

Good to hear. It's not working with my 2 external DAC/amp (FiiO & Centrance) with Kitkat except when using UAPP/UARP. No such issue with 4.2.2.
[G2 General] farhanito:
Yep, no issues here with Fiio E07k DAC.

I'm using G Pro2 ROM, though
[G2 General] droidsg:
I'm also having the the audio bug when using it with my Samsung earpiece. It's so annoying. When I use my friend Beats Audio the hissing become more obvious. Anyway who knows to get root on kitkat?
[G2 General] shudoha:
for root ...

go back to 4.2.2 and root ... install pihlz recovery last version and chose your custom rom ( optimus lg pro 2 V4 its better)

clean for installe new room .

install kk baseband

installe rom

reboot and enjoy

but the noise is still there

or if you do not turn off your phone you can always make a loopback

the sound much much better after elt test
[G2 General] BigBoyPL:
Still nobody answered how it's going on Slimport with sound.

I think it's gonna be a hard task to hear noises coming from TV speakers. At least with my old TV ?.

BTW, assuming Slimport uses digital signals, I bet we'll have a good result. Just like when using USB Audio devices.
[G2 General] BigBoyPL:
I was asking for SlimPort because when you do hdmi test, noise is other.
[G2 General] joeyvanhummel:
I sent a tweet to my local LG service twitter account, but no response whatsoever in a couple days.

I just tested it with the slimport. No distortion or hissing sounds. In fact the sound quality is better than using the audio jack.

Audio Hissing/Crackling on Headphones.

This is present on all Kitkat roms currently. Some users don't get it most do. Type of headphones seems to be a factor. The following fix is temporary and will revert after a reboot. So needs to be repeated if your phones reboots for any reason.

Type in phone dial pad 3845#*802# and it will show Hidden Service Menu.

Click on "ELT Test", select "Manual Mode" and select "Test Start".

With headphones plugged in select "Audio Loopback" and than select "Test Start".

Blow gently into the microphone and keep on this test 20 seconds or more.

Once done back out and play music. Enjoy!​
[G2 General] P_Toti:
Is that taken from my post ? Anyway it's not enough, you have also to set the option on my mod and all is still under testing.

Nope, its from a Chinese friend, so I dont know if its working or not bc I dont have the issue. That why I posted here for pp to test.
[G2 General] P_Toti:
MMM ok. It's not enough. I could be enough for some headsets though , but as you can confirm(you don't have the issue or to say better you have the issue but you can't experience it with your headsets) that could also unnecessary for some headsets so...

more hissing and cracking

but a light breeze

when you put the sound not too loud

i believe this is a equalizer bug, can someone try changing their default equalizer to viper4android and tell me if you hear it, alot of 4.4.2 roms have this, google did something they werent apost too

the solution mixer path works. the hissing and cracking sound disappears

but a light breeze appears when the sound is too low.

which is not disturbing since in general the music you listen loud enough

You need the xposed framework

Sound Tweaks--------------->Fix Hissing Headset issues

Remember to reboot after enabling the option

If you have rebooted with the headsets plugged in remember to unplug them because the mod is activated when you plugin the headset.
[G2 General] shudoha:
ok but your mod is compatible with rom port lg g2 pro optimus 4.1 ?
[G2 General] P_Toti:
Probably almost tweaks, quite sure that option should be compatible.
[G2 General] mannequin:
i think many people are wondering what's causing this bug, please share your findings about it's origins.
[G2 General] shudoha:
but cloudyfa solution works

and when i I do a manual test ELT in hidden menus

audio loopback for 20 seconds

little breath disappears completely and the sound is very good qualities

until the next reboot of the phone

it just be a way forward for future permanent solution

---------- Post added at 09:20 PM ---------- Previous post was at 09:18 PM ----------

try cloudifa solution. works . just a little breath when the sound is too low . when you play music
[G2 General] P_Toti:
Actually i posted that solution before :silly: and with my mod you should solve the issues without doing that test at each reboot.
[G2 General] shaarky:
It's working. I was experiencing the same as you are describing but it was before reboot. So reboot is a must !

I also enabled the settings and replaced file as adviced...however it's not clear whether both needs to be done or not.

Anyway, it's crystal clear now ! (D802B, KK - CloudyStock 1.2) Thank you ;)
[G2 General] shudoha:
ok i install your framework and your apk for test
[G2 General] P_Toti:
Enabling that option on my mod and replacing the file is what you have to do(but it's still under testing). If you only replace the file you could still have the noise with some headsets
[G2 General] shaarky:
Oh, I forgot to mention, I'm using original headsets. Just enjoying music now ;)
[G2 General] shudoha:
ok thx your apk works great .

damages whatsoever in English

if you search french translator . contact me

Thanks i have already a french translator. It's in english only because it's a beta the final will be avalaible also in the french language ;)
[G2 General] ephumuris:
What does the xposed part of the mod actually do then? I'm happy we have a partial solution. But it would be nice to have an xposedless method as I don't have a need for xposed except for this fix now.

[G2 General] :
extremely long shot, but seeming we got same hardware versions.

go back to clean 210a Netherlands, (including wiping update registery in go back to stock method)

root, custom twrp recovery. Backup efs everywhere(off the phone on computer). download mahdi rom, D802 patch, banks gapps, super user zip. reboot recovery, wipe all but internal. flash mahdi, patch, gapps, superuser. Let it boot. Listen to the same music, try to reproduce issue.

boot recovery, wipe everything in advanced wipe. switch off, download mode and flash 210a. let it boot. dont configure it. turn off download mode, then with clean install of lg mobile support tool flash 220b.

thats my installation path. I dont think it should, but it could work.

another way would be check if your music is certain codec\quality bitrate. try a different one to reproduce, that way we illiminate codec issues. :)

at own risk, seems like warrantee may be lost.

My Sony MH650c give very noticeable hissing sound but the MH1 has no hissing at all.

This is weird.
[G2 General] Frutek:
No. This is completely normal :) It all depends on sensitivity and impedance of your headphones. Lower the impedance and noise will be picked easier ( also depends on sensitivity). It also depends on the device output impedance.

Hi, I updated my G2 through OTA yesterday in India. Everything seems little faster including the battery drain. The worst part as mentioned by many users I am hearing the hissing noise during listening to music. This is very annoying. Any solution to resolve this issue. LG customer service is pathetic in India and they dont know to handle such thing. So I am looking for some solution from the users. Pls help.

I'm not a developer so I can't do that but is there someone here who can code a xposed mod, who resolve the problem? A mod who just do that?

I've red that tweakbox beta do it well, if you move one more file, for example. But you have to install a huge mod for that (and still in beta). What do you think about that?
