Noise on audio line - Verizon Samsung Galaxy S 4

my s4 does this thing where if i connect it to my car's line in AND to the charger it plays a hissing noise behind the music. i thought this was charger/car specific, but then i tried one of my work's PA speakers and it does it too without being on a charger where everyone else's phones, mp3 players and computers dont do it. is there something wrong with my phone in particular? if so how do i fix it; or is this a hardware issue with the verizon s4?
funny thing is the cable for the work speaker is unbalanced but again it works with every other device with no noise

My S4 does the background noise with the car charger thing as well, but it shouldent over the PA, most of the noise from charging in a car comes from alternator noise, plugged into a wall outlet or not, the phone should not have any issues in most any other situation. Another Q, it only does it on the work PA? Is there any way to try another cable?

Yeah we have plenty of cables, all did it, also about the alternator noise I tried my ipod and a friend's s3 and neither did it in my car...
It only does it on the pa, not on headphones nor other wired speakers but then again it's the only thing I plug in that isn't balanced
That's why I'm thinking it's software, phone or unit specific

If you think it might be software related, I would try a different ROM (after a NANDROID on your current ROM) just to see if it does anything different. If not, then (from a software perspective) you could discern what items on the ROM could be causing the issue and try to deal with them.
Another simple way to see if you can dial down or out that distortion is using a EQ app to adjust the sound levels and whatnot. If it doesn't work at all, then that MIGHT rule out a hardware issue.

Headphone bug? uneven volume

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).

High pitch noise when plugged into car's AUX

Full description of the problem:
I just got my EVO 4G LTE the other day, as a replacement to my original EVO 4G. However, I noticed when it was plugged into my car's AUX port, it puts out a high-pitch (like a teapot) noise. This noise happens as long as the headphone jack is powered up (something playing). Even if I turn the phone's volume down all the way, the high pitch is still heard. Otherwise, the audio from the phone can also be heard normally.
Things I've tried:
1. Different cables known to work. All act identically.
2. Headphones. They work fine.
3. Another car's AUX port. Worked fine.
4. Jiggling the jack on either end causes the pitch to change momentarily, but does not go away.
5. Slightly unplugging it from the car side (so one of the channels is not connected) makes it go away, leaving me to believe the high pitch noise is only coming from one channel (I believe the right channel, hard to tell).
Things I don't want to do:
1. Get a new car stereo.
2. Use a Bluetooth adapter. I already have the Stereoclip, and it doesn't do phone calls. Anything else sounds awful with music.
Does anyone have any solutions? I think its some sort of strange feedback/grounding issue, but I have no idea how I would fix this.
I don't have a solution, but I am experiencing the same issue with the phone plugged into my car's AUX. As long as music is playing I can't really hear the whine, but between songs it's pretty annoying.
I haven't tried playing around with the different EQ settings. By default it's been going to Beats. I may switch to a different setting or try a different player like Winamp. I'm currently using the HTC media player.

In my experience it has absolutely nothing to do with what app is being used, nor the EQ. It's nothing software as far as I can tell.

The car charger makes no difference. I have tried using nothing but the audio cable in the phone and still had the static.
I was under the impression that a normal ground loop would require a charger, but...
Modplan: are you sure this will fix it if the noise occurs even without the charger plugged in? The noise is high-pitch, not really a hum, so I'm wary as to whether it will help here.
Its not a simple ground loop problem. I wired my power to the phone using a separate ground from the car's common ground and the issue still persisted.
Try cranking the volume up then when you hear the noise, start playing with the touchscreen. When i did this the noise started changing according to the movement of my fingers. I concluded that there is something going on with the grounding of the capacitive display thats causing another grounding issue, but its not an issue with the car, but an issue with the phone.
I didn't want to go through the vicious cycle of returning my phone over and over until i get one that didn't have this fault so i just went with a samsung hs3000 hardwired in to my car.

Headset Jack's other issues
I can confirm the same behavior with my EVO 4g LTE. My HTC Touch Pro 2 or Iphone 4s never had any of these issues with my vehicle's AUX jack. I also verified that if I turn the volume on the phone all the way down that the noise is audible on the vehicle's sound system. It also doesn't matter what player I use or if I add any equalizer settings to the audio. Finally, the noise is present whether the car is running or not.
Can you guys confirm: If you pause the audio on your player does the whine end about 4 seconds after and startup again if you press play? Or if you shut the player down does the noise go away shortly after?
I did some research and some said it has to do with the AUDIO DAC in the phone turning on and off as audio is played, paused, etc. If the output device has high sensitivity these sounds appear.
I had another issue with my Plantronics wired headset distoring when making phone calls. It did not present the whine but it distorted the callers voice as if the treble or bass was too high. I tried various audio settings but nothing changed. With other headsets the issue does not present itself. I think that the audio DAC is also sending higher/lower frequencies that are greater than some headsets can handle.
That Kensington thing that was posted can easily be made with common household parts. Basically all you need to do is take the big bulgy thing from any cable that would have it and attach it to your audio cable. It works best if you have one near each end of the cable. it's called a clamp-on ferrite bead and is just a clip with iron ferrite in the middle. Since i'm new I can't post a link buuuut what I can do is tell you the keywords to look up on google for the ehow link: cable magnets eliminate emi . enjoy!

Dankorzon, is this what you're talking about? If so I'm going to go get some tomorrow. I'm having this feedback issue too, but it is only when the car charger is plugged in. But I'd love to get rid of that sound. Drives me crazy.
SOLVED: I used a ground loop isolator
I posted earlier that I had the whining noise in my car even with the engine off. So it wasn't related to an alternator issue. I use a Blitzsafe (blitzsafe.com) device to add a line level input jack to my Honda Accord's stock radio interface. It works well with all my other devices except the Evo 4g LTE. This past weekend I did a little tinkering and noticed that if I pulled the RCA jack on one channel (left or right) every so slightly so the ground tabs weren't touching the noise disappeared. With only one channel connected the noise is not present. I'm not sure why the noise is present with both channels connected but it definitely pointed to a ground loop problem. I did some research in audio forums and some said that a wire could be jumpered so the RCA ground touches the receiver chassis and that would solve the problem. Unfortunately that did not do anything. I touched several different grounding points near the receiver but the sound was always present.
I went to Best Buy and purchased this: http://www.bestbuy.com/site/Fierce+...36.p?id=1218186610567&skuId=9855136&st=ground loop&cp=1&lp=1 It works great. For whatever reason the EVO 4g LTE's DAC must be sensitive or not have the right filter to block the ground signal. This explains why the Kensington product also works.
I also solved my headset issue. I can confirm that older corded Plantronic headsets will not work well with the EVO. The EVO distorts the speaker in the headset. I'm pretty sure it's because it sends lower bass frequencies than the speaker can handle. Only solution was to use a newer headset.
Thanks all for your help.

That is what he is talking about, but that is NOT what the kennsington device is. Google "ground loop isolator" for info on what the kennsington is, it is NOT simply an aux cord with ferrite beads on it.
I've got the same problem in my car. This only happens when plugged into the charger. I'm going to try a ground loop isolation device which will arrive sometime next week.
I guess I don't understand why the phone would only do this when no music is playing though. It makes me think maybe a patch could solve the issue if HTC knew what the issue was.

Odd whistling noise when connected to aux input in car

I've got an aux input in my car, and today when I tried plugging in my GSIII, I got met with a faint but annoying whistling sound underneath my music.
It stops if there's no sound being sent over the wire, but the moment a notification (or music) starts playing, it comes up.
Car worked fine with my DX, and still works fine with my friends' iPhones, but I get the stupid sound with my brand new galaxy siii. Oddly enough, it works fine with headphones.
any ideas guys? I'm kinda stumped.
Search ground loop isolation. You are getting dirty power to your phone.

Do you have the phone charging through the cigarette lighter? You can get ground noise from there, and it will be transmitted through the phone to your stereo.
Hm. Let me try again without it charging, but that's strange. Why did my old DX not experience this?
Assuming that's the issue - will a different cable solve the problem?
edit: So I checked the phone without plugging it into the charger. Still get a whistling noise. It's really more like a high pitched hum. I notice that if I don't plug the plug in all the way it doesn't happen (but I think I only get one channel).
I'm getting the same thing, and it's driving me crazy. At first I thought my brakes were going bad in my car!
I've tried different audio players and apps, but it still always get the noise. The phone is not charging, and I did not get this with my old captivate either.
Any ideas?

I am having the same issue. First time experiencing it though; never heard it with the iPhone, HOX, or NS
I'm using a line in cable, and when i jiggle it, i can hear the noise change tone at the same time. I have a feeling it might be because it's a regular stereo cable and the microphone combo jack on the phone is not working right with it. But that's just a guess.
It's pretty annoying and its making the phone unusable as a music player.
Happens in my Lamborghini (Dodge Caravan) when using a MP3 player. Usually, if I run my hand down the cable it clears as though it's some kind of static build up in the cable.

try flipping the cable (putting the aux in side into the phone and the phone side in the aux in) it happens to me sometimes and if I flip the cable it clears it out I couldn't tell you why though. also make sure there isn't any dust in the ports or on the cable ends.
That noise you hear is most likely due to the electrical system in the car. I rent cars all the time for work and never know the shape the electrical sys is in so to resolve the issue I bought a Kensington Cable from amazon and now have CD quality sound from any music app including pandora & spotify.
Hope this helps.:cyclops:

Not sure what you mean by "the electrical system" and the "shape" of it. Could you clarify? As I said, I have no problems with other devices in this car.
I would usually suspect something wrong with the car, or maybe a ground loop, but I can plug in my Galaxy S (Captivate) or iPod with the same cable, same everything, just switching out the phone, and the noise goes away.
The way the noise cuts in and out between songs, and when I close the music app, it seems to only happen when the audio chip is getting a signal or is being energized. This is making me think that it may just be a noisy chip :crying:
I was on conf call with SGS3 plugged to AUX, no power charging was going on. And either noise canceling didn't work, or noise was getting in thru AUX line to receiving end. I didn't have problems listening, but ppl on the other end complained, and I had to mute the mic.

sorry! Could you speak up please? I couldn"t hear you over the sound of your e-penis
I am having the same problem. My HTC Thunderbolt never had this problem. Same car and cables, I get the hissing and popping until I play something. Then it goes away until I stop the music and then it comes back again. Weird and disappointing.
The problem comes from the 4-pin (TRRS) audio jack in the GSIII combined with presumably bad grounding in my 2007 Honda Accord, or the Aux adapter.
I fixed it with a simple DIY solution. I cannibalized a TRRS headphone jack and bought a TRS (3-pin) port from radioshack. I clipped off the jack with a generous portion of wire, then stripped them and cleaned them from their insulation (they are covered in insulating dye).
I connected 3 of the wires to the TRS connector, and taped the whole thing up. No more hum.
Also known as Road Noise. Where the power cable and audio input are too close to each other. Electrical current emits a small magnetic field which will hinder audio quality and promote road noise from the alternator.
This is a very typical senario in car audio install, when you run the power cable and rca right next to each other.
this buzzing noise happens to me every time i drive my car for the past 3 years:
solution: turn down the car volume. if you keep your car volume half-way, then you wont hear it as much, or you wont hear it at all.... you can make the phone volume as loud as you want though. also, as you accelerate faster, the noise gets louder. watch, try it.

Static when connected to Aux input in car and charger plugged in

I just got my S4 this week. I recently changed phones from the Note 2.
When I play music via the 3.5mm cable to my car's Aux input I hear static only when no sound is playing. Also, the quality of the music isn't as good as the Note 2. I would suspect that the clarity, range and overall quality of the S4 would at least be at par to my Note 2.
Just this morning I unplugged the usb charger and the static stopped. I have not been able to replicate this issue with headphones or other chargers. Normally, I would suspect that one of the cables are going bad. However, the same cables work fine with the Note 2.
There appears to be the metal of the charger is hitting the metal bezel/border around the phone that the 3.5mm input is resting on causing (grounding?) the static. Has anyone else experienced this? Is it a known issue? I want to make sure it's not a defect on the phone.
If anybody have any solutions or recommendations on better cables please let me know.
Thanks

I used a different charger when I tested the headphones. I'm going to try headphones with the same charger tonight. Is it possible there's an internal short or ground causing this? I read other people having static over the audio but I only hear the static when no music is playing that includes changing songs.
There is a known issue with SOME GS4's and their headphone jacks causing static or crackling noise during playback. It is a random issue and seems to be an issue with certain types of headphones or whatever is plugged into the jack. For example, you can use the headphones the phone came with and they are fine but some aftermarket headphones have the issue. This is 1 reason why i didn't preorder my phone online but went into a corporate store and had them test it before they set it up.
My advice, is since you're inside your 14 day return policy i would return for a new unit.

Same issue here
I'm having the same issue with static/buzz between tracks with the charger plugged in. I believe there is a grounding issue in the phone itself. I've had several other devices plugged into the same cable with no issues. It's really annoying. What's odd is that there's zero buzz when a track is playing. It only happens when the tracks change.
Update: I just checked it with a coworker's S4 and the same issue is happening. Also, if an audio application is not running the buzz is heard when the charger is plugged in. As soon as an audio application runs the buzz goes away until the songs/tracks change and then it's only making noise between the tracks. Seems like something in the audio section disconnects when there's no audio. Definitely a Samsung issue.

Ok so it gets more interesting. I grabbed my wifes S4 which I got from a differnt store 3 weeks apart from my as well as the fact that mine is the white variant hers is black.
Now what I have realized at least in my vehicle is that it only does it for her phone when I have the aux cable plugged in AND micro USB is plugged in and charging. If I remove the micro USB the cutting/popping is none existant. I will try it with mine tomorrow. I suggest you guys try the same thing and post results.

Ok so it gets more interesting. I grabbed my wifes S4 which I got from a differnt store 3 weeks apart from my as well as the fact that mine is the white variant hers is black.
Now what I have realized at least in my vehicle is that it only does it for her phone when I have the aux cable plugged in AND micro USB is plugged in and charging. If I remove the micro USB the cutting/popping is none existant. I will try it with mine tomorrow. I suggest you guys try the same thing and post results.

I do have the exact same results with both phones tested when micro USB and Aux Cable plugged in. Sorry for not making that more clear in my last post.
99% sure this is a grounding issue in your car, and not a problem with the phone. My old Droid Bionic, Droid RAZR, and now my Galaxy S4 all do the same. It's a grounding issue, not the phone. Do I know how to fix it? Unfortunately no.

Definitely not a grounding issue with car. Once an audio app turns on there is no noise, even when music is paused it's dead silent. I also was able to reproduce the issue with a set of computer speakers in the house to eliminate the possibility of the car causing the issue. It is a ground problem but it's in the phone. Samsung is disconnecting something in the headphone section of the phone when there's no audio apps running. If I plug in my micro USB and AUX jack in the car with all audio apps closed I get a constant buzz. It sounds similar to the sound you get when you touch an audio cable that's plugged into an amp. I've tested three phones now all with the same problem in different cars.

Wow, so I'm definitely am not alone. It's exactly as everyone describes it. I also tried using the same micro usb charger and a headset instead of my aux cable and no issue. However, I just bought this off Amazon which eliminated the issue with my current phone. :
Kensington Noise Reducing Car Audio AUX Cable for MP3 or SmartPhone, including iPhone 4S (I can't post links but that's the title on Amazon)
I'm also Verizon also sent me a new phone to exchange my current but it sounds like the new phone will still have the same issue with my old cable. I'm debating on whether to just send the new one back or not since i just burned one of my three screen protectors.
But I can defintely confirm that if it's not a defect and an actual flaw in the phone then those headsets eliminates the issue.

Seems like its a wider-spread issue and no you aren't alone. I also have an issue with the volume dramatically increasing and decreasing while plugged into my AUX in my Tahoe. I was poking around the other S4 forums for the ATT, TMo and Sprint variants and its apparent there too. However the consensus is that issue is related to The Google Play Music app and more specifically the EQ.
I have had 'noise' on my AUX line in my truck before and it would be expected without a ground isolator however it seems worse with my S4.
So it seems that common wisdom here would say that a new replacement phone would not do any good?
-Lil'
I had the same issue in my truck with the s3. I think it was a ground issue.
There was improvement with the replacement device bu5 the issue wad still present. But the Kensington wire does eliminate the noise so it's definitely worth checking out.

Audio qulity from headphone jack

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.

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"?
