While watching youtube or playing video via SD card from my Nook Tablet (rooted indirect method, 1.4.0) I get a very annoying static/popping noise before the audio plays at the start of a video or when resuming from a pause. This is only present when headphones are attached. Almost like the device mutes the headphones while no sound is present then clicks/pops/buzzes for a split second when audio is detected before playing. This is happening with three different pairs of headphones and multiple browsers/players. The noise is in relation to the volume set on the device... If I turn the device up to max the static is louder then if the volume is set at half. I see this problem while the device is charging and also when it is not.
Is this problem common and people are dealing with it or am I alone? I did a forum search but didn't see any posts relating to my question.
thanks for any comments.
I have the same issue, and it is rather annoying. I am hoping it is a software issue with the rom, where the ramp between dc and audio is not being handled correctly. It would suck if we had broken hardware
Did you happen to try headphones before rooting?
Maybe related to my "clicking" I get when my NT is sleeping with WiFi on... hopefully a software bug and not shoddy design/materials.

Nope, seems unlikely that would screw with it though.

I think it's a software issue. We all have noticed it at some poont.
thin wired headphones
I've noticed this before with thin wired headphones, especially when around a computer. Thick wired headphones with more insulation / protection are a bit less likely to have this problem.
... just a thought... might not work in this case.
Nook Color was just like that. cm7 make it perfect.

Yup! It happened for a long time. I realized that it cause by the sleep mode of sound chip but it is a software bug... -_-
Last time I use it for the song picker for the annual dinner event and it keeps pop pop pop before start playing. I solve the problem by minimizing the volume but not stop playing.
Finally someone makes a thread about it! I noticed it very early on when I bought my Nook Tablet in last December. It bugged me a lot. I couldn't find much about this problem; all I could find was a similar problem reported with Nook Color. The description of the problem looked so similar that I assumed Nook Tablet has inherited it... I hadn't registered on XDA forums then and decided to live with my assumption.
It has nothing to do with root. I discovered it after rooting it, reverted back in hopes of curing it, it stayed. It persisted when it auto-updated to 14.1. I was hoping this was one of the bugs B&N fixed with the update, but apparently their only motive for the update was to block users from side-loading apps.
This annoying audio issue manifests in at least two different ways. With some headphones, NT emits bursts of hisses before starting the playback. With others, there's no hiss but there's a pop. The hiss is more bothersome than the pop. I have tried with a few different headphones, and only on one I hear the hiss. On the rest, I hear the pop. I don't know why it behaves differently with different headphones. Maybe it's something to do with impedance.
My take is that NT turns off the audio at the hardware level whenever it doesn't detect any audio playback. It comes back on with a prelude of a pop or hiss. The idle period needed shut off audio is very little (maybe 1 second or so). Maybe it was done to conserve battery. This makes playing any musical instrument app very frustrating. Once you pause before playing another note, you automatically get a prelude of a pop or a hiss.
Speaking of musical instrument apps, another thing that makes NT quite unsuitable for enjoying those is a lag/latency between hitting the touchscreen and hearing a sound.
Is there any other way to fix it as we wait for a stable version of Cyanogen ROM? I'm not sure. I have seen some lines dealing with audio on build.prop. I don't know editing which parameter to what value would help things, so I didn't mess with them. Maybe someone more knowledgeable would like to try? I will try myself if I can learn more about it.

Hi All,
When I use headphones (tried 3 different pairs) whenever I listen to any audio output, whether from a game, mp3s, radio, system noises, there's always a lot of static and/or hiss. It's in the background and not too terrible but I'm thinking there's something wrong with the hardware in my Photon. I tried taking out the battery and it made no difference.
Anyone else have this issue? Should I return it? Any advice?
Thanks!
I use Moto bluetooth headset to listen and don't have any additional noise over what would normally be there (say, compared to what it sounded like on my EVO).
Do you get this background noise through the phone speaker as well or just the headset? Might be something with the audio plug on the phone.
If you have tried other headsets and the phone speaker is either doing it or not, wouldn't hurt to take it in to a Sprint store and have them check it out.
Thanks CCallahan. I exchanged it and the new one doesn't do that so I guess it was just a fluke.
I have the same thing going on, with headphones only. Guess it's just the luck of the draw

I would exchange it. I guess it is the luck of the draw. My new photon has been less buggy overall - not just with this issue. The other one wasn't terrible but there were a lot more fcs and hard crashes. Could be just coincidence but with the audio jack issue too seems like there just might be bad ones out there.
Hi all,
I have this static/buzzing noise whenever I play music. It just stays there in the background and it's completely noticable. I also get this sound, whenever I get a notification, like a sms, e-mail etc. also, if I turn the volume to 0 and I play a song, all I hear is that static/buzzing noise.
But, whenever I pause the music, the noise stays there for a few seconds and than it dissapears. But when I play music again, the static/buzzing noise comes back...
I have tried different roms, kernels, music players and different earphones.
None of the above seemed to solve my problem.
Could anyone help me?
Thanks!
Have you tried other headphones? Have you experienced this on other devices? I ask because it is normal to hear a little hiss/noise from audio devices when they're powered and no signal is coming through if the volume is up. Just some devices have more than others... If it's buzzing, though, that could be a bad ground in the connection. It could be the headphones or the headphone plug on the phone.
If another set of headphones doesn't do the trick, you may have something faulty on the Evo. That is if you already went back to full stock to test.

I tried many headphones, no static noise when it's in an iPod. Never experienced a static noise on my iPod.
so you tried other pairs of headphones in your evo? Not just compared ipod to evo right? The plug could be touching a little differently in the evo between headphones and might be completely different in an ipod. This is why some people experience tracks skipping randomly when there's an inline mic.
But if another set of headphones with the evo produces the same problem, it could be faulty hardware. might have to get it replaced if it's that big a deal to you.
Good luck, just hope I could be more help. It'd be easier to hear and get a clearer idea of what is happening exactly.

Well, I had this since day 1 of my evo. My mother's sgs has this too =/
I have noticed that the audio crackles when using the stock music player as well as the google play. This happens both through the speaker and multiple headsets. It also occurs also whether playing from a file stored locally or when streaming. It is most noticable when listening to a talk show since there are pauses of sllence which make the crackling stand out. It is not near as noticable when using the poweramp app. It is not the same issue as mentioned in the "Official Sound Quality" topic in the International Galaxy S3 forum since this occurs whether the screen is on or off. Has anyone else noticed this?

Yes. At the gym today, my audio crackled about 2 times (headphones). Very annoying but w/e
The Onex I had would do this at times as well, arrgh. Was hoping this would not be an issue with the S3. Is this an android thing ?

How?
I'm getting crackling sound from the internal speaker when I use Gallery to play a video.
Also getting crackling from my left front tweeter when I use bluetooth in my car. I don't get it when I use the 3.5mm audio jack though. Nor does it come from any other speakers in the car.
And getting cracling from internal speaker while using Jango.
Don't get it while using iHeart though.
I am having the exact same issue as mentioned in the OP. I posted a thread in Q&A and no one else mentioned having the same problem.

When connected to car's stereo via bluetooth ... it crackles/cracks/pops/chips after every 5 - 10 seconds. I tried playing different audio files - same results. Play video clip - same results. Played youtube video - same results.
When I connected the phone via FM transmitter ... there was no cracking/popping in sound. I will test it again with a 3.5 mm auxiliary jack and update the post.
It looks like its a hardware issue ... however since these phone are not in the stores yet. Its hard to get a replacement handset right now.
Problem is so bad that its impossible to carry on listening to music or podcast ...
Uh oh.
I have a U.S. (Canadian, same thing) model SIII and I have a SQ problem. It only appears at very low volumes but my quieter music sounds like it's passed through a kazoo. This disappears when I turn up the volume. I don't think it's the "crackle" issue I've seen frequently described on other forums, because it occurs continuously when I output audio through the headphone jack, not only when the screen is off. This problem occurs across apps and file formats, including my flawless FLAC collection. I've played the same files back on an iPod touch (320 kbp mp3s) and the iPod has no problems. I'm really, really hoping this isn't a hardware issue, because I've already exchanged 2 S IIIs at the shop I bought it from due to screen issues and the manager's visibly pissed at me for cutting into his margins If it is though, looks like I'll have to face him again... He might even refuse to exchange it :/
Samples:
In the attached .zip, one .wav was recorded from a video played back using the stock video player on the SIII on the lowest volume setting (this problem persists on other player applications).
The other .wav was recorded from an iPod Touch playing back the same video on its stock player, also on a very low volume setting (much more clearly than the SIII).
As you can see (hear), it's terrible on the SIII... any idea what's going on? I think I have the same issue as enaybee. If any of you with SQ issues could check out the samples and see if that's also what you're experiencing it'd be great

I am having the same issues of cracking and popping when using my bluetooth on the preinstalled car system on an 07 gl 320 mercedes. it appears in the "bugs" post re Samsung GS3 about the popping and cracking.
It is horribly annoying and obnoxious. it's so loud at times I can't even hear the other person on the other line.
I'm taking mine back to the VZ corp store I bought it at and going to work with a tech there to see if it's just mine or if it is on a replacement phone as well.
I had an HTC One X that would do this when playing music from Spotify and using a Bluetooth headset. I have not had this with the S3. I imagine that this is a software issue, likely related to Android.
Same issue here
I have the same cracking / popping issue. I spent 1 1/2 hours in a Verizon store last night convincing them there was a problem. I paired my headphones with an in store display and the sound was fine. Had them listen to my Galaxy and they could hear the cracking. The connected one of their headphones to my phone and heard the cracking. Finally, they agreed there is a problem with the phone. Unfortunately, there (apparently) are no white 32gb available anywhere at this time, so I am waiting for a backorder.
Not sure what they were looking at, but they later mentioned (while searching for a replacement device) that they have had other reports of the same problem.
UPDATE: cracking in Bluetooth/not with plug in speaker/headset/installed speaker
Last night contacted Samsung on Chat Tech Support. Their response was they haven't gotten anything listed yet and suggested I call back if the problem persists when data is more prevalent??? Reviewed multiple posts today on different forums. I listened to headphones via the 3.5mm jack, listened to the installed speaker, and no popping/cracking noted. Called my Corp VZ store in Ocala, FL this am and advised of situation so they would hold a 16g white GSIII for me. Arrived at 8p this evening. Had salesperson sit in my vehicle while I made several calls.
The first couple calls while connected to bluetooth there was scant noise. Then I received an incoming call that cracked/popped. The salesperson in his infinite wisdom advised me it sounded like the person was speaking too loud into their mic and that was causing feedback. (SERIOUSLY. I pay to be blonde! I'm a freaking techie! bygones..) Anyway, he said he would call level 2 tech support. After perusing my phone and it's setting I'm sure in an attempt to make sure I haven't rooted yet, which I hadn't, the Level 2 Tech support stated he didn't see any problems like this listed in the database and it's probably a lack of compatibility with the Bluetooth 4.0 and my system, so they would not replace the phone, as it's not their issue.
As my blood started to boil, again them assuming that because I'm female, I don't understand, Uggh!, I tried to control my temper and got stern advising them i've had the px for less than 48 hours. I drive 500 miles a week. I must have hands free communication and this SUCKS! I stated of course your system doesn't show the defect yet. The dang phone just came out. The salesperson witnessed the problem and blew me off. I advised him that I found the posts here on XDA and his response was "People on those forums lie about the problems they're having."
REALLY?????? Now the temper flared. I said "I may be female with blonde hair but have an advanced medical degree, am obviously more tech smart than he is, and advised him he was an idiot. (yes, I know that doesn't get anything accomplished, but it at least made me feel better.) His response was "what would you like me to do. If I give you another phone it may have the same problem." And my reply, "and IT MIGHT NOT!" Again I referred to the other listed people who have a similar issue that wasn't present on other devices. He blew me off. I told him I would have a new phone in my hands by morning and left the store.
On my long drive home I called VZ tech support on my phone, explained the above, and she advised me I had to call back on a different phone. I advised her I've already called Samsung, the factory reset didn't fix it, I'm NOT reseting it again, I unpaired and re-paired the bluetooth, the store person went through the settings already and was blown off by tech support, and that I WANTED to use the phone so she could hear the interference. She put me through to Level 2 Tech Support after she heard the interference as well. Had to explain AGAIN. Well, the tech noted my account and I should be getting a new px in the am at a different corporate store under the 14 day warranty for a new phone. Will keep you posted on the results.
Other than this bluetooth issue, the phone is awesome. Have not had any other glitches. But if this persists, it's a bust. Have to have bluetooth that works!
Hello everyone
I just got my archos 80 g9 turbo and I am really happy for the price.
But unfortunately I have a problem with the sound. If nothing makes a sound for some time , the sound becomes distorded like white noise. If I change the volume the sound is fixed until is silent for a while and becomes distorted again.
I tried re initialize everything as it seems to me like a software problem but no luck.
Anyone had the same problem ?
Edit: I think it is completely random when noise starts. But after sometime just stops....

Hey buddy,
i've got the same problem with my just bought Archos G9 101 Turbo.
Sometimes there comes a crackling noise out of the speakers. Sounds a bit like an old reeeally dusty vinyl record...
Is there any solution available?
I tried many software wise tweaks to solve the problem, nothing worked. So i rma it and hey send me a new one. Even the new does it but much less so i can live with it.
I have seen 3 archos 80g9 and all of them had the same problem ,so i believe its a design flaw...

I am on my second Archos G9 101 250GB Turbo. I returned the first one because of random crackling noise from the speakers (and for the phantom screen clicks). Both problems still exist on my replacement device. The noise occurs at random times for a few seconds then stops. I have noticed that it only occurs when the WiFi is on.
I use the Archos solely in the car as a media player (connected to my stereo via aux-in) for hours on end without ever getting the crackling noise, yet when I get home and connect to the WiFi…there is the noise again. I am not sure if this is software or a hardware issue.
I can live with this though because it works flawlessly as a first rate car stereo.
Yes, there are differences unit to unit. What I observed that the 2 units that came out of the box with honeycomb had this issue much more than the one that came with ics.
I am not sure if it is hardware or software either, my impression is still that is software because it is audible from phones and also looks like the crackling noise continues until the stream is over.
For example:
You play an mp3 and it starts with crackling sound.
The sound continues to be crackling until everything is silenced for a couple seconds
Then everything is normal.
But it appears to be random (haven't test with wifi turned off, I use it all the time with on ).
If some dev can check sources for solution or identify the problem I would be thankful

I have not heard the crackle noise on my Archos for a about two weeks now. I use it as a media player (mp3) two hours a day everyday in the car. The Archos is in a dock on the car dashboard connected to my car stereo via Aux-in, I hardly ever hold it in my hands
The Archos 10i G9 Turbo is totally standard OS wise. I have replaced the original 250GB HDD with a 512GB SSD and because I only use it as an MP3 player and nothing else; I have disabled every application I was able to. I no longer use Bluetooth or WiFi.
I suspect it may have something to do with (based on my observation only and not on scientific basis):
1) WiFi connection?
2) Holding it?
3) Use of internal speakers?
4) Heat?
5) Software?

I think the problem is impedances, but the device that causes the problem is........?????
if the reason is this design flaw and not well protected the speaker.
Are speculations but together we can get something clear

4.0.6, upgrade to 4.0.7, rooted and now with [email protected] V3.
I just got a G9 80 with v4.06 on it. If it's plugged to the charger & charging, the electrical garbed sound will be there when typing or upon playing music/videos. If the charger is not plugged it, the garbed sound is intermittent when playing sound.
Seems like faulty hardware or a design flaw to me.
I will try the following when I reach home later:
1) upgrade to 4.07 & test
2) Test with earphones inserted
Results:
1) upgrade to 4.07 & test (same issue )
2) Test with earphones inserted (clean sound playback, so it's the speaker only.)
I found out something upon inserting a usb thumbdrive to the G9. I have no sound garbed when the thumbdrive is inserted & enabled.
This is true for games & music, but when playing videos (Big Buck Bunny), sometimes the problem is still there. The inserted thumbdrive seems to reduce the frequency of garbed sound.
Can it be a grounding issue?
Hi
Everything you say makes me think the same thing, shielding is the problem, i do not know if the speaker or cables are not well insulated.
I think the key word here is impedances, with good insulation could be solved.
I not have so much electronic knowledge to fix it.
some electronic some out there who can help us ??????
Just wanted to know if anyone else noticed faint buzzing/scratching/hissing noises coming out of their headphone jack...
(and yes I have tested several headphones/earbuds and tested with my MDRv6's all with the same results. Its definitely the phone not the headphones)
When I insert my headphones there is a quick beeping sound that plays for a second or so then goes quiet.
When music is playing, especially soft music (a particular song was Instant Crush; Daft Punk) there is a hiss in the background, specifically when certain tones play.
It was terribly noticeable right at the beginning of a few songs, especially the one I listed above.
I also have button sound effects enabled. So When I press one of the soft UI buttons it makes a tick noise. However for about 5 seconds after the tick there is a long hiss then silence until I press another button.
The volume of the hissing/scratching noises is directly related to the actual volume of the device and the note playing.
Im on stock build 11c w/root, and I havent found a lot of info about this problem.
Just wondering if anyone has noticed this, or if this is a known issue?
If your phone is warranteed, I would bring it in
The G3 boasts an AMPLIFIED 1 watt sound speaker, which means there is a powered sound processor.. Unless the jack needs to be cleaned, I would lean toward thinking there is a defect in your phones jack, or sound assembly. I think its more than likely a defective jack, especially if there are no sounds like you are describing when headphones are not in use
Yeah the phone is brand new. I think I'm going to RMA....

Just got my G3 a week ago and didnt use headphones until I read your post, I tested many different songs with different players, stock player, google player, Iheart radio, pandora, etc, headphone sound is crystal clear on mine, I dont get any beeps either like you described, I did notice you need to make sure the jack is pushed in good and tight, I put it in and thought it was all the way in and sound was crappy, pushed a bit harder and it clicked in good and sound was great, do you have a case that may be preventing the jack from being pushed in all the way, I had a phone in the past that this happened to me with, had to cut away some rubber on the jack to make it fit snug, if none of those are the issue, I would look into a warranty claim. I am using the beats audio earbuds that came with my HTC M7 I had before this phone.

That could be the issue. I know on the 2012 Nexus 7, it's really bad. It's supposedly due to the microUSB port and the headphone jack sharing the same circuit, or some engineering thing like.
Wonder if it's the same or if they didn't shield the headphone jack very well and it's picking up interference from the microUSB port when charging?
I didn't want to leave this up in the air so I figured I would post an update.
I replaced my G3 through Verizon for a brand new unit. My first phone was of an earlier batch (came with the 10b update) the second one was of a later batch and had 11b pre-installed.
Both phones had the same issue. There is a hissing noise/distortion that comes from the headphone jack. Even when not playing music.
I noticed it on other phones too but not anywhere nearly as much. I understand that any audio source is going to have a little background interference but the G3 definitely has a more significant issue than others.
However it seems to be entirely dependant on what headphones you are using.
1st. I tested first with my Sony MDR-v6's which the problem is most noticeable on. Extreme hissing/background noise.
2nd. Then I used a pair of Audio Techina ATH-PRO500's and the problem was almost unnoticeable.
3rd. I also tried my Steel Series Siberia v2's and the problem was again almost completely gone.
4th. I also used my receiver at home. JVC 5.1 channel receiver with RCA speakers and a Kenwood sub, didn't notice the issue at all. However there where some occasional strange popping noises when no music was playing I didn't get on my GS3 or other MP3 player.
5th. Finally I tried the ear buds that came with my Galaxy S3 and the distortion was again totally noticeable with and without music playing.
This is most definitely an issue that totally depends on what headphones you are using not sure if it has to do with sensitivity or impedance (this is what most people think) however it is most definitely an issue. I saw a few threads saying that audio issues were a problem in Android 4.4.2 however LG/Verizon have yet to release a stock base on anything but.
I suppose I could flash AOSP 4.4.4 and see if the problem persists but I don't know if that would even be worth it.
2 phones and 4 headsets later this is starting to seem like either a software or a design issue.
However I have nothing but good to say about every other bit of this phone. Really besides the audio jack top notch all around.

I might have found a workaround for this
I have tested 3 LG D855 and all of them have noise/static/high-freq leak from the processor out to the headphones. It might be a faulty design for the headphones amplification stage for headphones (when the headphones logo appears on the status bar). However, when using line level output (the jack appears on the status bar) the problem does not reproduce.
Therefore the workaround I've found is to trick the phone into line level output mode and then plug the headphones. To do this you need to plug in a 3.5mm jack extensor or a 2-to-1 3.5mm Y-adapter with no load, that's it, with nothing connected to it. At that moment, the phone will activate the line level output mode. Only after that you will connect the headphones, and you'll see there are no artifacts on the audio.
That being said, I'm not sure this will work with all kind of headphones as I have only tried with mines that are low-impedance ones, but on those it works perfectly. To be checked if the level of the signal in line mode is enough to drive other headphones.
In any case, it is a shame this happens with a high-end and expensive smartphone. I was hopping this will be fixed in a newer hardware revision but I got two replacements of mine and no luck. I have read somewhere this might be a flaw in Snapdragon 801, as it integrates completely the signal routings but isolates badly highfreq noise from processor stages, etc. etc. but I do not remember where I did read it unfortunately.
I hope this helps!

Ive been having the same issue. I have a pair of Shure SE846 which are about 8ohms. I experience the poor audio, especially the noise in the left channel. I find that placing a call and then listening to music removes the left channel static but the sound is still kinda bad. Ill try your suggestion tonight and post back. Just wanted to let you know your not alone.
I despise my G3 because of this. Im looking to get a new phone unless I can fix this.
Nope, my sound is perfect on my high-end Sony over the ear phones. Crystal clear on pure stock G3 .
I haven't noticed any artifact issues on my phone when using headphones, however when I plug it into my vehicle and also plug in the charger that causes everything to go nuts. The USB interference causes a crazy amount of excess noise. I haven't ever actually tried listening to headphones while charging, so in the car is the only time I've ever noticed it. The same issue occurs when I plug in my Galaxy Tab Pro into the aux jack and charge it at the same time, so this is definitely not unique to the G3. I wish all phones had as good an amplifier as my HTC DNA does, I still use that thing for music because the sound is so good.

If your phone is warranteed, I would bring it in
The G3 boasts an AMPLIFIED 1 watt sound speaker, which means there is a powered sound processor.. Unless the jack needs to be cleaned, I would lean toward thinking there is a defect in your phones jack, or sound assembly. I think its more than likely a defective jack, especially if there are no sounds like you are describing when headphones are not in use

I'm having a different audio problem.
With headphones plugged in and listening to music using any player, the right side sound emits distortion/hissing noise at a certain frequencies. When I tested it with plugging a 3.5mm to 3.5mm to an external amp (JDS labs c5) the distortion/hissing noise is completely gone. So it's definitely not a faulty jack
The hissing is evident at the beginning of (first few seconds) Tina Area's Still Running and You set fire to my heart .
I'm testing it with sensitive iem (Westone Um3x).
So does this mean there is a problem with the internal amp of the g3 or more to do with the os bug that can be solved with a custom kernel or update.
Is this a common issue found on all g3s?

Hi! This worked perfectly for me but for me instead of tricking the phone into line level output mode, I detaching one side of my headphones before plugging it into the headphone jack then reattached it afterwards. I'm using pair of sensitive iems (Westone um3x rc)
Everything is quit with no distortion, just how it should be!
One thing, is there an option within android or an app that can permanently enable line level mode ever time headphones are plugged in without having to trick it.
If so, I won't have to sent my phone for repair!
Also are there any disadvantages for using line level with headphones?

Using line out shouldn't make any difference on audio quality. It only disables the remote (buttons and microphone).
Would also really like a way to force the line-out mode. Btw, does this affect all G3s? Cause right now I'm not sure if it's worth the hassle of replacing it.

I know but some how using line out causes the hissing from the right side to go away completely. Strange huh
Are you also having this problem?
I also don't want to return mine if it exists in all g3s and there's a easier work around.
Yea same thing. I have artifacts in the left channel except when I manage to force the phone to recognize the headphones as line-out. I did this with the adapter to test it and it's impractical if not impossible to use the same adapter all the time.
I'm gonna try doing this right this moment to see if it works: http://forum.xda-developers.com/lg-g3/help/hissing-noise-left-ear-playing-music-t2804065/page17

I don't use earphones with a volume remote or microphone so that's not a problem.
It could be more to do with the increase in output impedance but I might be wrong cos the volume level is identical to headphone out.
I'm also getting a lot of static background noise but it disappears after making and hanging up a call as mentioned in a thread.
But yeah a permanent fix by forcing it into line out or doing some changes in kernel would be much more convenient

Great news! I just tried the fix from that thread and it worked. Here's the post: http://forum.xda-developers.com/showpost.php?p=59601465&postcount=150
I'm using stock rom which had 3 mixer xml files and I edited 2 of them, mixer_paths.xml and mixer_paths_qcwcn.xml. Also, instead of changing the value to 0, I deleted the entire line as it was suggested later in the thread.
The artifacts/noise in the left channel are gone!

But mine is stock on stock Lollipop via official update and with the hiss coming from the right side.
Please excuses my ignorance but I know nothing about accessing and editing a ROM.
How do I get into the rom and into the file called system/etc"?
