First of all: This is my first post on XDA so Hello to everyone!

That hissing left earphone really bugged me, so I tried on my own and it worked.

Configuration: G3 D855 + CM12 Nightly 03.11.2015 (Lollipop 5.0.2 based)

There's a file in "system/etc" in my case called "mixer_paths.xml" (it can be mixer_paths_qcwcn.xml depending on ROM)

Inside You'll find those two sections:

<path name="headphones">
<ctl name="SLIM RX1 MUX" value="AIF1_PB" />
<ctl name="SLIM RX2 MUX" value="AIF1_PB" />
<ctl name="SLIM_0_RX Channels" value="Two" />
<ctl name="RX1 MIX1 INP1" value="RX1" />
<ctl name="RX2 MIX1 INP1" value="RX2" />
<ctl name="CLASS_H_DSM MUX" value="DSM_HPHL_RX1" />
<ctl name="HPHL DAC Switch" value="1" />
<ctl name="HPHL Volume" value="20" />
<ctl name="HPHR Volume" value="20" />
<ctl name="RX1 Digital Volume" value="60" />
<ctl name="RX2 Digital Volume" value="60" />
[B] [COLOR="Red"] <ctl name="COMP1 Switch" value="1" />[/COLOR][/B]
</path>

<path name="headphones-advanced">
<ctl name="SLIM RX1 MUX" value="AIF1_PB" />
<ctl name="SLIM RX2 MUX" value="AIF1_PB" />
<ctl name="SLIM_0_RX Channels" value="Two" />
<ctl name="RX1 MIX1 INP1" value="RX1" />
<ctl name="RX2 MIX1 INP1" value="RX2" />
<ctl name="CLASS_H_DSM MUX" value="DSM_HPHL_RX1" />
<ctl name="HPHL DAC Switch" value="1" />
<ctl name="HPHL Volume" value="20" />
<ctl name="HPHR Volume" value="20" />
<ctl name="RX1 Digital Volume" value="60" />
<ctl name="RX2 Digital Volume" value="60" />
[B] [COLOR="red"]<ctl name="COMP1 Switch" value="1" />[/COLOR][/B]
</path>

Change "COMP1 Switch" value to "0" in both cases. Make sure permissions are set to -rw-r-r- or 644 and Reboot.

Let me know if it worked for you.

Thank you very much. It worked perfectly with Resurrection Remix.
[G3 Q&A, Help & Troubleshooting] Crude Dude:
Hello. I'm having similar problems reported on the topic and also a lot of noise with the headset's microphone, both for calls and for audio recording. I tried another headset and the problem repeats. I tested the two headset on a Nexus 4, did not hear any noise. Someone else can confirm noises in the headset's microphone?

Hi,

I have a problem. I'm on latest international stock. I edited the mixer_path.xml directly with ES Explorer and afterthat the sound doesn't work at all. I also tried a factory reset (also a hard one over powerbutton+sound down). However it doesn't chang anything. I also checked that the file hast permission -rw -r -r. Any Idea what I did wrong?

---------- Post added at 04:55 PM ---------- Previous post was at 04:02 PM ----------

Fixed by copying another mexer_path.xml from a working device.

WARNING: Don't edit the xml file on the device. Copy it, edit, copy back and set permissions.
[G3 Q&A, Help & Troubleshooting] sniper07:
I had a similar problem when I changed "HPHL DAC Switch" value to "0".

There can also be a file called mixer_paths_auxpcm.xml which also may need to be changed.

So is the left earphone hissing gone after copy-paste method?
[G3 Q&A, Help & Troubleshooting] Racer-1:
On mine it's gone. Worked great.

hissing problem

I am running a stock 5.0 android on my G3 and the file looks whole different and I am not able to find the shown lines :(
[G3 Q&A, Help & Troubleshooting] Biou_Pilgrim:
I am using VinkingWay 1.2 (based on the stock V20i) and values are already to "0", and i have still the hissing issue. the only trick working on my device is to plug an aux cable first then the headset. ( My device shows the aux icon).
[G3 Q&A, Help & Troubleshooting] sniper07:
As far as I know LG in their ROM complicated whole audio thing to make G3 support high definition 24bit/192kHz sampling.

rabyli, could you PW me the file? I'm curious to see what's inside.
[G3 Q&A, Help & Troubleshooting] Biou_Pilgrim:
Acording my driver status in viper4android FX i have only 48kHz sampling (It's enough for my outside headset ^^), where did you get this information about this 192kHz sampling?
[G3 Q&A, Help & Troubleshooting] sniper07:
Qualcomm WCD9320 audio codec supports it natively (it's a part of Snapdragon found in G2/G3).

I have links to some reviews/comparisons but xda won't let me paste those here.
[G3 Q&A, Help & Troubleshooting] BlackRabbits:
Could anyone comment on what changing <ctl name="COMP1 Switch" value="1" /> to 0 actually does?

Actually, checking my own device the COMP1 switch is already set to 0. Any ideas?
[G3 Q&A, Help & Troubleshooting] ikerrg:
Hi,

Are there any news about this problem? I have just got a brand new LG G3 D855 (v20h) with 32 GB and 3GB RAM, and it has the same problem with the audio through the headphones (hissing noise in the right channel and sound artifacts in specific tones). The "make a call" workaround fixes the problem for me, at least temporarily. I have not tested the fixed "mixer_paths.xml" because I do not want to root it right now. I have read that LG fixed the problem in the G2 with a software update. Do you think this could really be fixed in a future software update?

Thanks,

Iker.
[G3 Q&A, Help & Troubleshooting] yoohoo:
Guys, just completely remove the line

<ctl name="COMP1 Switch" value="1" />

will solve the hissing problem.

If slight hissing still persists, simply reduce HPHL/HPHR volumes by 1 each time and reboot until hissing is gone.
[G3 Q&A, Help & Troubleshooting] BlackRabbits:
So can you comment on what comp 1 actually does?
[G3 Q&A, Help & Troubleshooting] Mr Sliff:
Thanks for this thread. The sound was really annoying me and I was considering getting rid of the phone. I changed the switch one to 0 and changed the hphl to 18 and its perfect now.
[G3 Q&A, Help & Troubleshooting] Biou_Pilgrim:
I ve deleted the both lines and set HPHL and HPHR to 18.

First fix that works for me T^T !!
[G3 Q&A, Help & Troubleshooting] yazilimcionline:
I have same problem now. And like happened after root and custom rom with try different kernel. Because previously i dont have this issue. My problem, only not left side. Both of them have hissing noise with Dialler and play music especially acoustic songs.

But....

The problem is fix when phone call. First, plug the headphones and hear the hissing noise. Then unplug the headphones jack, call some number and Within 1 to 2 seconds canceled call. Plug the headphones again and test it in dialler and music player. The issue is fixed.

i don't know why this is happening but tomorrow going to service.
[G3 Q&A, Help & Troubleshooting] sulkie:
Thank you so much for this! I wanted to return my phone because of it.

I'm using stock rom and i deleted those lines in both mixer_paths.xml and mixer_paths_qcwcn.xml, and did not change the HPHL/R volumes. All good now!
[G3 Q&A, Help & Troubleshooting] HohoTheOwl:
OMG GUYS!!!!!!!!!!!! I HAVE FOUND A FIX!!!!!!!!!!!!!!!!

If you have headphones with a detachable cable, YOU ARE IN LUCK!

To fix the hissing noise, you have to detach the cable from the headphones, and plug the cable alone into the phone. This is so that the phone doesn't RECOGNIZE that there are headphones at the other end. You should see an icon different to the normal ones, YOU SHOULD SEE A CABLE, not a pair of headphones as an icon! After this, plug the cable into the headphones. The phone will continue to not recognize that there are headphones plugged in. NOW THE DISTORTION SHOULD BE GONE AND YOU HAVE A LOT BETTER LISTENING EXPERIENCE! ALSO, this proves the fact that is IN DEED A SOFTWARE PROBLEM. Its fixable yay! im glad if this helps, only found this out yesterday ;)
[G3 Q&A, Help & Troubleshooting] lenders88:
Hey guys! That noise is really boring of course. I thought it was a hardware problem, but after the "making a call first" trick now it's ok.

But there is something more that is driving me crazy men...after being so concentrated during these days to hear any noise, I found out that left channel is really lower than right one. I noticed it also with other earphones (galaxy s3) but I always used earphones so it's strange for me that the problem comes out only now. Plus I'm a musician and I've got a perfect hearing thank god.

With s3 earphones, that have got buttons and mic in the right channel, I hear more power on the left one, so it seems that there's volume loss on the cable that hosts the mic channel and buttons.....is it possible? AND with an akg phones (without microphone) the volume is perfectly balanced, but also with Apple earpods. In these two cases, that sucking icon is the jack-like one, and not the one with headphones...

As I said, it's really driving me crazy, do you have any ideas/solutions about it?
[G3 Q&A, Help & Troubleshooting] psittacus33:
I confirm that this works.

I tried the other method editing the mixer_paths.xml and mixer_paths_qcwcn.xml files, and the G3 stoped playing any sound. :( I tried to replace the files with the original ones but no luck... had to flash the ROM again.

Cloudy 2.5 here.
[G3 Q&A, Help & Troubleshooting] sociojeje:
Well for me, the problem is the cable icon. When the phone recognizes my headset (bose qc3 or soul sl300) as aux (cable icon), then left hissing starts. While it gets worse when I use the phone (like touching and browsing) but it's gone when playing music. Not a big deal but still bothers me. However, when i connect a cheap skullcandy earphone, the phone correctly recognizes it as headset and no hissing. I assume it depends on the the types of headphone jack. I just hope if there is a way to force the phone to recognize aux as headset...
[G3 Q&A, Help & Troubleshooting] ikerrg:
Great!

Thanks a lot, sniper07!!! The fix really works. I have just modified the COMP1 Switch values to 0 on my CloudyG3 2.5 ROM and the digital noise of the headphones is gone! No more need to make a phone call to get rid of that stupid bug. That distortion was especially annoying when playing quiet songs (with silences and pure tones). Thanks again for finding that fix. The only drawback is that root access is required to implement it in a stock ROM.

I Have no sound too after method with mixer_path!!!! help

Hi,I have also the problem that i have no sound know?! what i have to do ;im not so good in stuff like root ,please help(Ps.im from germany)

i tried to write the lines down like they were before but it doesnt work......

my sound doesnt work too.I tried to edit the lines like before but it dont worked.Please help me im a noob in things like this !!!...
[G3 Q&A, Help & Troubleshooting] sociojeje:
I think people seem to have different hissing problems. For my case, I don't hear any sound distortion when music is played. I simply hear the hissing noise from the left earpiece when no music is played. Touching and swiping the phone screen seems to make the noise more distinctive like switching the home screen page. My wife's one has the same problem. However, the noise is gone with cheap earbuds. It only exists with certain headsets (relatively larger and expensive ones). In addition to the hissing noise, I hear something like popping sound when music starts to play which I don't hear with cheap earbuds. I start to suspect this as a hardware issue... I think there are two (at least) kinds of 3.5 jacks. For example, a certain 3.5 mm headset cable (cable only) is recognized as AUX without the headset attached. Strangely, i have the noise problem with aux icon as opposed to most people here. My wife's g3 also has a problem with aux icon. No noise with headset icon....
[G3 Q&A, Help & Troubleshooting] ikerrg:
Probably you broke the files when editing (many android text editors have size limits and save chopped files when editing). Always edit the files outside and then copy them. You could have also changed the owner of the files. They must be root,root (use chown to change). Make sure the permissions are set to 644.

chown root.root mixer_paths.xml
chown root.root mixer_paths_qcwcn.xml
chmod 644 mixer_paths.xml
chmod 644 mixer_paths_qcwcn.xml

Anyway, I can send you the original files and the modified ones if you want.

Cheers.

well i had something REALLY odd happen to the phone today that has never happened before ! the phone was laying on my dashboard whilst i went off and did some work. on my return i picked the phone up to book my client in for 6 weeks time. i went to open the diary in the phone, and the phone went crazy ! ! ! it was jumping to all different screens, opened the calender, then shut it again ... jumped from app to app then back to home screen. this must of carried on for 10 - 15 seconds? i ended up having to power the phone off to stop this random behavior. once i turned the phone back on .. it was fine ! could it of been that it was really hot today and the phone over heated causing this ? it was just really bizarre :eek::eek:

EDIT .. just tried to txt a friend and the txt screen is behaving really odd now too ! its like im holding my finger on the screen .. so its putting numbers insted of letters although im only just making contact with the screen as light as i can ! and its not hot now ! and it even tried to call the person i was txting . something VERY odd and wrong suddenly started on this phone today

[Xperia Z2 Q&A, Help & Troubleshooting] valdigre:
Did you leave your phone on the dash, in a closed car, at the sun? Especially the black version of Xperia? Black color is the color that accumulates the heat from sun the most, which results in your Xperia just toasting inside. I cannot imagine how hot it become on the inside and outside. Software might not help with this, you might have simply melted some connections or something like that...

Can I know which rom version you are using right now ? Because before I update my D6503 to 402 , I also have the same problem. But it's not about heat I guess. If you have ever run any huge 3D game under hot sun, then see how hot the body can be. It still work fine in that situation . So try to update it to last version and see how it going ?

Clearly you can't read. The phone is certified to withstand water correct. Water does not mean heat. Heat and water are two different things. Google them and you will see as it seems you have a difficulty with understanding the difference.

Disappointed? That's user error. Not the phones fault. You should have not left it in the heat. The phone can't walk or go somewhere else.

If you want something that works in heat get a Nokia brick or something.
