So I installed Neutrino on my Atrix yesterday (I'm not sure if that's relevant or not, but I figure it's good to know), and everything was working perfectly fine. However, earlier today the audio from my headphone jack started to sound completely distorted.
It's not the earbuds, because they work on other devices I have. And the audio from my speakers and from HDMI works perfectly fine.
Has anyone had this problem, and if so, is there any way I can fix it? Or is my phone screwed?
Did you play with equalizer settings any (DSPmanager or similar)?
I didn't. At least, not at first.
DSP Manager actually started to crash on startup about the same time that the audio from my headphones would be a problem. I thought reinstalling it would fix the problem, but it hasn't. Though, the louder I make it, the more "clearly" I can hear what I'm playing (it still sounds like satan farts, though).
I also tried cleaning the headphone jack, but that only helped a slight bit.
Would it be worth reinstalling Neutrino or is my phone died?
I'd say it's worth a shot. Make a nandroid, do a full wipe, and then flash your ROM. If that doesn't help, then at least you can be fairly sure it's not the software.
So I'm bumping this, with a little bit more information of what I've tried and what my problem is.
I've tried uninstalling and reinstalling DSPManager. Didn't work.
I made a Nandroid backup, did a full wipe, and tried to play music again. Didn't work.
I actually tried to install Beats Audio Drivers to see if they would help. They didn't.
This is what my phone's audio jack currently sounds like, without the high-pitched humming so pardon me if your ears hurt.

I actually tried cleaning the inside of my headphone jack and it seemed to help ever so slightly.
Would this mean my headphone jack is toast or does anyone else have any ideas what the problem could be?

I'm not sure, but it sounds like what you're hearing is the difference between the 2 channels, rather than the channels themselves. This would happen if the common ground connection is broken somewhere in the audio out. It's an easy theory to test really. All you need is an audio file that plays on either the left or right channel only. If you have sound out of both channels, then there's your problem, if not, then it's something else.
Actually, this sounds like a poor connection that is overcompensated by extreme loudness so that some of the electric current is strong enough to pass through. I've heard what the "no common ground" sounds like many times, I don't think this is it.
The headphone connector is not actually soldered to the PCB but instead sits on it on springy contacts (makes for very easy repairs and replacements at service centers). I'm almost willing to bet there lies your problem.

Maybe. But if that is the case, wiggling the plug may give some indication of that without disassembling the device, just as would playing a single channel file. In both cases, the jack would likely be the culprit, but given how fragile the device is internally, taking it apart should be done with extreme caution.

I tried playing a mono sound file, and sound files that play through only the left speaker and only the right speaker. They all sound like they have the same problem, so we can rule that out.
Though, I will mention that the sound that is heard is on maximum volume, and that's the only time I can hear anything at all. If I go down just two notches, then I start to hear nothing.

Just a thought, but have you tried another pair of headphones?
Edit: if the headphones are good, then the only other thing I can think of is a bad section in the audio chip. The schematic shows the headphone output is separate from any of the other sound outputs, so it is possible that the chip is bad. Unfortunately, if that is the case, the cheapest solution would be to replace the main board, but it's a delicate procedure.

Yeah, I'm sure it's not the headphones. I've got two; a set of headphones and a set of ear buds. Both of them are functional in other devices but do not work in the phone. Also, the audio clip was direct feed with a different chord, so the problem is surely with the phone.
I'm at the point where I'm willing to open up the phone to see if there is a problem with the jack itself. If it is corrosion or another problem with the jack then I can try some repairs. If I do have to replace the main board then I'll probably wait on that and ultimately purchase a new phone.
One thing to note is that the audio quality does not improve if I move the jacks around inside of it. However, I do hear a sort of rubbing sound from the headphones if I am moving it around.

If the jack is the issue then it shouldn't be too bad to replace. I was looking at different websites earlier and they look to be really cheap. The thing I have to stress though is just be careful, and don't take apart the phone unless you can replace the phone itself just in case something should go horribly wrong. I know that should be pretty obvious, and generally people tend to underestimate their own skill level, but I have encountered a few people in my time who have what I consider to be the opposite of the Midas touch, and their attempts at repairing anything end up as more of a hate crime against the very thing they are trying to fix.

I plugged my headphones in for the first time today and i realized that the left side was quieter than the right. And I unplugged it and replugged it in and it was fine. Then I tried it again and the left side was lower again. I'm not sure what's causing this or if my tablet is defective. But it seems like a hit or miss on getting even volume from both sides.
Anyone else having this problem or can test it out?
I have te same issue and it happens every time I plug in headphones and its annoying.
For me this only happened when I use my SGS2 headphones on Nook.
Actually, I found that SGS2 headphones only work well on the SGS2. With my laptop they have tons of noise, on nook sometimes I have uneven volume.
Although on SGS2 they have the best sound I've ever heard in headphones..
Have you guys tried other headphones?
I only have the one pair of head phones and they are a generic brand from dollar general and they dont have any issues when i use them with either my pc or psp or phone for that matter

Headphone bug
Yes I too have that problem. Glad to see that it's not just me & mine.
Stupid question - for those having issues, have you tried wiggling or rotating the plug once it is plugged in? Sometimes I find if I have a spot of oxidization on the plug it will cause said uneven volume. It could explain the difference that occurs when you unplug/plug back in.
Another thing to try would be to plug them in when the device is asleep to see if that helps. If there is anything that tries to reduce the "pop" of the sound of plugging in the headphones it *might* affect how they sound after the fact.
Just grasping at straws here based on my experience with other devices.
I was having this problem until I realized I only had my headphones plugged in half way. Don't mean to be a jerk, but have you tried plugging your headphones in just a little further?
Sent from my DROID BIONIC using Tapatalk
no amount of fiddling with the plug helped me at all still have the issue and its annoying since the speaker isnt loud enough when I am out and about.
Another thing to consider - another issue I've had with certain device/headphone combos is that some headphone jacks either don't have a long enough plug or the plastic jacket of the jack interferes just enough with the plug in the device to affect sound (essentially related to downsay's comment). Try a cheap pair of 'phones from the dollar store with a simple jack and see if the problem persists. If so, perhaps the device is defective...
These are a cheap pair of head phones from dollar general lol.
Edit: Plugging the headphones in while the device was asleep seems to have fixed the issue for me for now. Sound is equal in both cans now
I have tried 4 different earphones, they have been plugged in all the way. Some people have no problem, so I'm beginning to think this is a hardware defect. I'm going to exchange mine and will let you guys know if there is a difference. I'll also try out the display model and see if it suffers from this problem.
Glad to hear you got them to work. Please do let us know how it goes with returning the nook tablet.
Sent from my DROID BIONIC using Tapatalk
I replaced my Nook twice partially due to this issue. Same problem on all three and it's always the left channel that is not connecting properly. I have found that I can get a good connection by plugging the jack in slowly. I think this is more a software issue than a hardware issue.
Yea just exchanged my tablet as well and the same issue is there as well as the one at the store. Plugging in slowly does help. Just before it engages the last click, if you hear both channels you're golden. Hopefully this is a software issue because it seems to be random. Unfortunately the one I exchanged has a creaking case, so now back to exchange again.
I stopped by Radio Shack this afternoon and purchased a $5 female to male 1/4" stereo connector. It seems to have solved the problem. I had similar problem years back with an iPaq PocketPC. Due to the shape of the hole on the iPaq/Nook, the headphone/earphone connector isn't inserting deeply enough.
Another solution would be to use something like a Dremel Mototool and shave away some of the excess material on the headphone/earphone adapter, so it can insert a little bit deeper.

What is everyone testing their audio on? The stock media player? Video (what program)? Is it on every application you try?
I haven't had any issues with audio in games, websites or MX player at all other than a loudish pop when some programs start up, but I'm using a set of Denon stereo headphones (so, good (large/long, gold) headphone plugs on it, jiggling the connection does nothing).
I'm not sure if this has to do with the x2 or just cm7 but I can't seem to figure it out. The audio without headphones is perfectly fine, but with them only the instrumental parts can be heard occasionally you can hear kind of a digital chirp of the vocals.tried figuring it out in dsp and music settings but nothing. Any advice on this is very much appreciated.
Sent from my DX2 w/Cm7 using XDA App
No problems with or without my headphones under CM7. Maybe your headphone port is bad?
Have you tried hooking up a different pair of headphones to see if it might be the headphones or the connector?
Have you tried it under a different ROM to see if you're getting the same problem?
Is this something that you only experience when listening to music with your headphones? Try checking the audio port to see if its got any lint in it. You can clear it out with a paperclip and you might be surprised to see how much has built up. It'd also be a good idea to test your phone with other headphones.
If this is happening with/without headphones, I'm not sure what would cause this. Maybe try a different music player?
It's happening to me, only on CM7

This happened to my Inspire 4G with CM7.1. The problem dissappeared upon installing ICS with aospX and kept working fine with IceColdSandwich, but several other problems forced me to return to Gingebrear. Now with CM 7.2 the problem is again.
It is not a total attenuation. It is a DSP setting that seems to be optimized for karaoke, because it selectively suppresses voice frequencies. However, all settings in DSP manager are turned off. Turning on Stage Virtual Room barely improves it. I can hear some voices, but really bad.
I think it's probably your headphones wearing out. I had a similar problem and a new pair of headphones immediately fixed the issue.
you got a case on that phone? I stopped using my otterbox 'cause every time i plugged in headphones, they'd act very stupid (sometimes giving the "no vocals" thing, sometimes cutting in and out)
I've also noticed that some headphone jacks don't do a good job of locating themselves and you can actually push them too far in.
I use a set of samsung headphones that have four contacts on the 3.5mm jack instead of the typical Tip-ring-sleeve three contact design. these are the ONLY headphones I have used that give me zero problems (unless I use the otterbox case along with them)
between the stupid angle on the hole for the 3.5mm jack on the phone, and a plethora of minute differences between jack designs, generally the X2 and headphones are a marriage made in hell...
stereo bluetooth works perfectly however
Hi,
Im wondering if someone can help!
I use my headphone jack everyday.
Today the headphone stopped working. Initially I thought it was the headphone so i tried 2 other pairs. Nothing. Cannot hear anything. I play music from the speaker and that works fine. But as soon as i plug in I dont hear anything.
Searching through the other threads, I found lint mentioned. So i blew in the jack and also tried to a pin. It appears to be clean.
Using an app I selected for a wired headset to be the only output. Now, when music is playing and when I putting in/pulling out the headphones in I can hear a crackling noise but nothing else. When turned up fully there is also some static!
Ive reset my phone so I know its probably not a software issue.
Any ideas please?
1. Try to hold the audio jack to one side (that is, press it either left or right) to make it slant on a side. Check if you get any sound.
2. Try seeing if you hear music by inserting the audio jack at various "depth" into the phone. i.e. don't insert it fully.
Hope it helps

tried both..but nothing!
you tried the other solutions from the forum? corrosion problem, etc? That's the best I can help. Otherwise, you might need to change the audio board, it's available on ebay I think for < $10, and apparently not so difficult to replace as well.
Let's check it with a torch. I also had this issue and it was not so easy but I managed to remove a little lint with a needle. After that it worked fine for me.
Hi,
This has now been resolved. It turned out there was another bit of lint I had missed. So using a needle, I took it out and the headphone is now back to its best.
Thank you all for your help!
Glad for you!
Hi all. New here, so hopefully this will be concise enough.
T-mobile HTC Amaze 4g, no mods, all stock plus a few apps. Everything working fine on the phone. Purchased a Platronics BT headset, works OK; limited range, but passable. Just bought a Sony MEX-BT4100P car unit. Did the install myself (retired auto technician, so I know a little about doing it correctly). All working OK, BT pairs fine, functions all good (Phone book, redial, etc). Problem is a buzz noise during calls, only audible on the other end of the call, but it's pretty loud. Sound is similar to a slightly shorted mic cable. Voice is audible, just a loud background buzz. No noises with any other car stereo function. No noises with any other phone function.
Talked to car stereo vendor, they sent new unit and microphone. No change. Talked to HTC. They say that since the Plantroncs works fine, there's no problem with the phone.
I'm trying to find out if anyone else has experienced this specific issue and if so what had to happen to resolve it.
Any thoughts? I don't have another BT phone to try
Android 4.0.3, Sense 3.6. Don't know what other info might be helpful.
Thanks.

Hey Charlie,
I remember having a plantonics headset. They were awful for me and they broke eventually. Did you try another headset? I think the headphones you're using could be the source of the problem. Hopefully someone else experienced in BT and headsets can assist you.

The Plantronics headset is fine; it's the Sony car stereo BT function that's making the noise...
It's been a while since I've had the stock ROM on my phone, but try looking under the settings menu in dialer for 'noise suppression' and make sure it's ticked.
Does your head unit have a gain setting for the mic? I had a JVC unit that had one in the Bluetooth menu settings.
Actually, I just looked up your manual, you do have a mic gain.
It looks like you also have an echo canceller/noise canceller setting as well. See what playing with those do for you.
Failing those options, it sounds like you have interference in your mic. Try routing it away from any wires that carry current. You might try just holding it out in the open and making a test call.

Head unit - I've tried all settings on mic gain and noise cancellation with no changes at all to the noise, although voice quality changed as expected.
Microphone has been pulled out of the car, literally to the full extent of its cable, with no change. I've wrapped the mic and its cable in tin foil and jumpered that tin foil shield to chassis ground with no change.
It does indeed to me sound like microphone interference, but nothing I do, including a different mic, changes the noise. Head unit and mic have been changed out for new.
Does it happen even with the engine off?

This tells me it's not interference, at least not from the car's electrical system. Do you happen to live under high tension lines?
Ok, here's what we've got in an extremely simplified flowchart:
mic------>head unit------->bluetooth-------->phone-------->person called
Follow the path, eliminate as you go.
1. Unplug the mic completely. Make a test call, see if your caller hears the noise still. If not, it's either the mic (replaced already, but not unheard of to get multiple bad ones. Try a desktop computer microphone?) or poor shielding in the radio (not easy to fix, even harder to locate.) If it's still there....still might be shielding in the head unit. Unlikely though.
2. You've already messed around with the head unit's settings. Nothing to do here.
3. Bluetooth. My radio used a USB bluetooth adapter, yours is built in. Can't try a different BT.
4. Phone. You don't know someone with a phone with bluetooth? If pairing with a different device results in a clear call, it's the phone (you could try rooting/updating/replacing it. Maybe they just don't like each other?) If the noise is still there with a different phone, it's either the head unit (you got another bad one or they just don't make them very well) or it's outside your control. Maybe the tower itself. You could try driving quite some distance away, till you're on a different tower. See if it's clear then.
Beyond all this, I really don't know of anything else to try, apart from getting a different head unit.

I did try unplugging the mic and the noise goes away, but according to Sony and the vendor, if a mic isn't plugged in, the entire audio chain gets muted automatically, so it's not much of a test. I'm going to see if I can dig up another mic like a computer mic with a mute or on/off switch and see what that might do.
I'm in a rural area and not too many cell phones I can borrow here. Might be one I can find...
I'll try another tower too; that's something I have not tried. But this really sounds like audio input chain noise rather than post-processing noise. I was an audio engineer in a previous life and I am still leaning towards mic-related issues...
Thanks.

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.

I've noticed it. Seems to be worse when charging.

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"?
