I've tested loopback, but again, not good enough.

Like SimpleX91 said, i'll wait for LG to fix it.

[MENTION=3623388]mannequin[/MENTION]

I'm not complainig, I'm just relaying my findings.
[G2 General] misteurz:
What solution? Install tweaksbox beta and move the file? Or something else?

Envoyé de mon LG-D802 en utilisant Tapatalk
[G2 General] farhanito:
Agreed.

Current workaround is not a solution.

Definitely needs a fix from LG.
[G2 General] mannequin:
yes.
[G2 General] BigBoyPL:
Guyz yesterday I've posted:

http://xdaforums.com/showpost.php?p=51371408&postcount=284

but 0% reaction so I guess that nobody want to know.
[G2 General] misteurz:
BigBoy, could you tell us more?
[G2 General] mannequin:
we do want to know but, again, there's a better solution already (if you're rooted and use xposed that is).
[G2 General] BigBoyPL:
Sure.

You need headphones with button to receive calls.

Tested on poweramp and stock mediaplayer.

So unplug your headphones and reboot your device.

When device will complete booting and be ready to use, plug your headphones.

Select your phone profile to Silent (without vibrations). It's really important cause without silent mode you will have good sound only in service menu.

Now play any song on music player. It must be over 1 minute long to let you do everything when music is playing.

Adjust the volume from 2 to 5 ( not less than 2 and not more than 5). It's really important because you can be deaf if you will adjust vol to max ;]

Ok so when the music is playing and you hear this annoying hissing enter service menu by typing 3845#*802# (802 is model so if you have 803 type #*803#)

Be careful ! This it is not fun. Click only functions that you understand or given here.

So if you are in service menu and in background you can hear music from headphones go to Device Test, then click Individual Item (scroll down), then click Loopback Test.

Now you can hear louder music without hissing. It's loopback test so you will hear your voice by headphones microphone.

You need to click "Hook Key Test", it's a key on your headphones.

Don't do anything more, just slide Exit button to exit.

Scroll down to click Back to Main.

Then scroll down to click EXIT

Click undo button or home button to exit from service menu.

Enjoy!

You will have good loud sound until you will unplug headphones or music will stop.
[G2 General] misteurz:
Hey, i've played with the N5 mixer_path.xml and i'm not sure if the "Reset to stock volumes" one is the good one for the LG G2.

In fact, i've flashe the "Headphone only Volume Boost" one, but the sound was so so so loud! unlistenable!!!

Is there a customised on especially for LG G2?

Or at least, can someone upload for me the LG G2's default one please? (4.4.2 V20b eur)
[G2 General] sanke1:
I did the first sound test from secret menu and now there is absolutely no hiss/crackling.

Just magic.

Surprisingly the sound quality is now better than 4.2.2. I also tend to keep volume 1 notch lower.

I will try not to reboot the phone. Read here that the hissing comes back after reboot.
[G2 General] misteurz:
so 'ive installed tweaksbox G2 and the N5 xml file : No hissing sound anymore, but what a huge loudy whisper!!

i try my earphones with my LG G2 and ith my Xiaomi Mi3 . What a difference...
[G2 General] P_Toti:
Why did you use the n5 mixer_paths file ? You should follow these steps http://xdaforums.com/showpost.php?p=51316528&postcount=254 and use the file you can find there. Try that and the issues should be gone.
[G2 General] philobolus:
No hiss or crackle here either. D800 running CloudyStock 1.2 KK Rom. Tested using sennheiser PX100 and logitech UE; checked with both mp3 and flac files; through stock music app and poweramp.
[G2 General] MatyGol12:
Can I use this if am not root???
[G2 General] SimpleX91:
No, it requires xposed framework.
[G2 General] misteurz:
ok, i can confirm that the solution written before perfectly works...

teaksbox + move xml file
[G2 General] BigBoyPL:
Nobody can confirm that my solution is working ?

I will not post any new tricks for g2.
[G2 General] shaarky:
The point is that your solution is too complex while we have permanent workaround working even after reboot....

G2 Tweakbox and replacing the file.

http://xdaforums.com/showthread.php?t=2549923
[G2 General] BigBoyPL:
Yes but you need ROOT and if you will do this you will lost warranty because info is saved to efs and everybody can check root status in service menu.
[G2 General] Frutek:
Still a bit noise after that. Although It's getting closer to 4.2.2 sound.
[G2 General] osmosizzz:
I've been blessed. So I took a chance and went for kit kat today and long and behold, No hiss or anything. Just as good as 4.2.2. Im using a D801 with CloudyStock 1.2 and I have the V-Moda M80
[G2 General] shaarky:
Not in case when going back to stock in right way I guess. Anyway, I "can't" use phone without root, so still is not a problem for me and maybe even not for others. But I didn't want to say that your contribution doesn't count.
[G2 General] tschmidt84:
Hi, could anyone who has updated to KK confirm that the hissing does not occur on the Google Play Music player? Thanks!

The hissing appear in the moment that plug the hearphones, occur in stock music player, google music,youtube, in launcher,,,,

[G2 General] getclikinagas:
Just updated.

The hiss is horrible. LG really need to fix this ASAP.

Not all earphones are affected by the hiss.

Lg quadbeat 2 : No hiss. Poorer sound quality.

Hifiman Re400 : Horrible hiss,left earpiece. Even at low volumes

Sony MH1C : No hiss. Poorer sound quality.

Hifiman RE272: Loud hiss,left earpiece.

Brainwavz R1: No hiss.sound quality better.

Xears TD4 : distinct hiss in left earpiece

I think the hiss is dependent on the impedance and sensitivity rating.

Maybe LG has messed with the output impedance, out put power rating in their pursuit to make it more "efficient"
[G2 General] lukeap69:
Even worse if you connect to portable external amp.
[G2 General] glai3:
I can confirm this trick works.

Using Power Amp, the setting and effect is preserved.

This trick is a little bit complicated but since G2 Tweaksbox mode doesn't work for me, its perhaps the only solution for the time being.

Thanks for your sharing.

And where put the file? Thanks!

[G2 General] BigBoyPL:
LG is relasing files by suffix.

Maybe it's not good when you must wait more for update but LG can share specific settings for each country by that way.

But now inside every European unbranded Kitkat you have same file.

And I have LGD802.APOLBK V20B_00 and I have hissing because it's still not solved.

I didn't saw V20C_00 for LGD802.
[G2 General] archheretic:
Hi guys, stupid question, does issue exist on Bluetooth? Thinking I could get one of those adapters that make your headphones effectively Bluetooth to get around this issue on my wife's phone?
[G2 General] The MBG:
My UK sim free from Amazon had the problem as soon as a pair of Sennheiser PX100-II were plugged in after the OTA KItKat update. Didn't bother trying any other headphones and went straight back to Jelly Bean.
[G2 General] johndoe-xda:
Same problem here with an open G2 32GB, suffix: ASWSBK, software: D80220B_00.kdz

Have the "tweaks box" devs figured out what the real cause of the problem is, or do they just use a workaround?
[G2 General] joeyvanhummel:
I've been using my LG Bluetooth Dock speakers daily without hissing, whereas on my SH HD429 it is very apparent.

Issue is nonexistent on bluetooth; this a problem related to the DAC in the phone itself.
[G2 General] putterill:
Bizarre, I'm getting the crackling on my chromecast, fine casting from a pc :-/
[G2 General] serious96:
strangely i dont find any hissing sound, using original quadbeat 2 headset, when plugging the headset or

playing original hifi or any file in stock music and google play music, both don't find any problem.

Build Number : KOT49I.D80220a

Software Version: D80220a-ESA-XX
[G2 General] :
The crackling\ static is sometimes random. The hiss can best be described as high tones that linger, Some.might not notice it as headphones may not reach it. Changing equalizer does nothing, it seems the range is warped.

Xposed takes care of some of the high notes it seems, yet overal sound is still warped, missing depth in my opinion. Tried the mods and different apps, but to no avail.
[G2 General] ahmad4u:
just flash a full rom !

do not update your device with OTA.
[G2 General] johndoe-xda:
Doesn't make a difference.
[G2 General] BigBoyPL:
I agree, flashed full rom.
[G2 General] :
Lol try omnirom, nice audio
[G2 General] johndoe-xda:
I don't see how it is funny that LG ships broken software with their product.

Also, it is not clear to me that this is a pure software problem. Many people don't seem to have audio problems with stock KK.
[G2 General] salisbury_steak:
I have this issue recently too.

I hear the hissing after pausing my music. But the hissing only lasts 3 seconds and then goes away.

This is regardless of the music player, and regardless of the equalizer (with or without V4A even).

The hissing only happens with my Sennheiser headphones though. No hissing with my stock Quadbeats.

Wierd issue indeed...
[G2 General] Det45ku11:
Got the bug (D802 32gb) using spiderio 380 4.4 V1 atm.

It comes crawling efter a while when i listen to music through whatever kind of thing, (except for headphones or the standard LG "earbuds")

~20-30 mins of listening then it starts to crackle/hizz in left speaker and it slowly becomes worse until it totaly owns the sound.

Kinda annoying.
[G2 General] Dorly:
Is anyone knows if lg is working on this issue :confused:
[G2 General] johndoe-xda:
Yeah I also contacted my local LG support and after a bit back and forth they said that their development team is working on the problem and they will contact me as soon as they have an update.

Dutch version, sennheiser momentum. 2h listening and no audio bugg. I have kitkat v20b
[G2 General] NeoVR:
Think its more of a KitKat issue than LG specifically.

Ive come from a SGS3 running Temasek CM11 and that always had a few seconds hissing after any audio (music player or system) was played.

Oddly my G2 running kitkat (v20b) doesnt hiss at all.
[G2 General] EdForce1:
Think it's a KK bug too, i saw an article somewhere stating that Sony are working on a patch for their models...

[G2 General] sanke1:
After running the ELT test manual mode, the hissing/crackling goes away till the next reboot.

Otherwise the sound quality on 4.4.2 is fantastic and 1 notch higher.
[G2 General] P010:
I've noticed a crackling in the left channel of my G2 since the OTA Kitkat update here in the UK on my SIM free model. Thought there was something stuck inside my Sennheiser IE80s at first but realised that it wasn't there on other sources.

Plugged the G2 into my PC line in followed by my 2012 Nexus 7 (also KitKat) and recorded them. The G2 certainly has a ton of background noise.

https://dl.dropboxusercontent.com/u/23595230/filez/audioTestG2vsNex712.ogg [950K - 57s]

Night and day to me... Some recording notes: Both devices were on max volume, I let Audacity amplify it on auto by 9.9db. The G2's output is noticeably quieter. The Nexus 7 decided to stutter a bit for some reason.

[G2 General] goodmamba:
I hear the hissing sound even with my Lg Tone+ Bluetooth stereo headset. It is present while music/audio interactions are present and it stops after 2-3 seconds after audio stops. For example, if bluetooth headset is connected and the UI makes a sound (notification, click etc) the hissings starts and turns off after 2-3 seconds after that sound is over.
[G2 General] giorgosfil13:
Unfortunately, I upgraded to KK today. The sound hissing is TERRIBLE. Other than that, it seems like a good upgrade. But since I'm an audiophile, I'm pretty frustrated. Now, listening to music with high quality headphones is impossible. I contacted LG Hellas and they said that they are aware of this issue, and they will fix it with a patch soon. I hope that doesn't take too long... But still, it's good news!

Just report the bug if you have a problem, reporting a bug using firmware that isnt OTA/KDZ conntected to your phone or if you dont even have the bug is counter productive. Then LG will track it, fix it and push it.

For those that do have it, does it become louder with higher volume and can you hear it when music is playing also?

I moved from open V20B (loud electronic noise and some hiss) to V20C (same problem) to vodafone V20A 16gb (only some hiss) to CloudyStock 2.0 (very little hiss).

I can't even say for sure if JB had less hiss than CloudyStock. :)
