Hello , how are you? First, sorry for my english.
I need help, and I think that you would help me. I have a G3, and I've noticed that the earphones are making a noise when a sound is emitted. I've noticed too that this happen only in Lollipop ROMS (stock based).
I've installed Kit Kat and CM12 baseds and the noise doesn't appears. I already installed via Flash Tools and TWRP, with all wipes, but the noise persists. I've noticed the noise after I've installed the app Sound booster for G3.
I dont think that is hardware, because in Kit Kat and CM12 works perfectly. The noise happens too in all sounds of system (including music, video).
I've tested with more than one earphone. And before installing the app to boost the sound, it worked perfectly.
The noise doesn't happens in speaker.
Can you help me please?
I have this little noise too, but i note that it happens only when charging. Disappears when not charging. Probably an interference. Between earphone plug and charge
It's a fairly common lollipop occurrence. It happens in other devices too...

I've just noticed additional noise whilst music is playing (on top of the beeps when plugging in and hiss whilst no sound is playing). This noise is best describable as unwanted distortion on sound of particular amplitude, though a quick experiment just now makes me wonder whether the hardware design is bad. (AIUI G3 audio's handled by the Snapdragon MSM8975AC SOC, unlike my old Samsung S3 LTE which had a discrete Wolfson DAC).
This problem is also VERY audible on the bundled LD "QuadBeat 2" headphones, in both ears at various points. I'll see if I can get a recording of it.
Methodology:
I loaded the "Wave" signal generator app and tested various volumes - noise is evident at particular amplitudes. I set the variables thus: a 100 Hz tone, 30 seconds duration, varying amplitudes. Finally set Wave amplitude to 0.02, turned the device volume to max and listened to try and ascertain whether this noise was being introduced by the chipset or the Android OS.
Results:
There's very noticeable 'fuzz' and unpleasant distortion in the left channel, which goes away both under and over a particular amplitude threshold -- which leaves you with an annoying band of amplitude where you will always have additional noise overlaid onto the sound.
Frustratingly, this is often in fade-outs or quiet passages of songs where you're listening most intently. It also renders the G3 useless for any kind of analytical or accurate audio output, a crying shame. My Google Fu is lacking too, because I didn't see this thread before buying mine... I wonder if installing CM12 might fix it?
Unless this is a problem with the stock kernels and the way they handle audio output, I'm becoming concerned that this handset is faulty by design and I'm going to have to swap for another make. Until it died, my old S3 had great audio capabilities, and a nice chipset to boot!
I've sent a customer service request to LG specifically about this. Here's what I wrote:
I'm experiencing significant audio problems with my new G3 handset.
When headphones are plugged in with no audio playing, I hear two beeps in the left channel. Then, a low level - but constant hissing - in the left channel, until the sound chip is initialised to play audio. The right channel makes occasional warbly, 'squeaky' noise, seemingly modulating with CPU activity.
Also, since updating at the weekend to Android 5.0 Lollipop (OTA via the LG Software Update process), I have noticed that whilst playing any audio, if I adjust the device volume to around 50%, additional noise is introduced into the signal chain (audible as a dithered 'fuzz' over the audio content).
I have tested with various pairs of professional headphones (I am a qualified sound engineer) and the problems are present throughout. I am concerned that these are significant design flaws. Please advise if a software fix is available, and whether these are known issues with this handset.

I 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!

Coming from a Galaxy S so I'm used to very high sound quality I got from the Wolfson chip using supercurio's Voodoo Sound mod.
I'm very happy with my GN except for one thing. I got this sound/ringing (sinus waveform in the 6-7 kHz range) coming from the left earphone. Sometimes it changes frequency when working with the phone so it could be some kind of interference. It's very quiet so I can only hear it for a short period after a sound has been played (while the output is active), but it's still very irritating.
I hear this with my primary earbuds of choice, the Denon AC-71, which are quite sensitive (110dB/mW) and has a quite low impedance (16 ohm).
Using a pair Sony MDR-P180 headphones I can't hear the sound. But these are not as sensitive (98 dB/mW) and has a higher impedance (24 ohm) compared to my earbuds so I can't play as loud, which could be the reason why I can't hear it.
Anyone else suffering from this problem or a similar one? Do you think my device could be defective or if this can be solved with a software update/patch?
Note: The problem persists through different firmwares, from stock 4.0.1 to the custom 4.0.3 rom I am running now, so if it's software-related it hasn't been fixed yet.
Seen quite a few topics on this, seems no one has a solution.
What I'm trying to accomplish with this is to see if EVERY HTC One X has this problem of a hissing noise in the background.
The hissing noise sounds somewhat like television white noise, and is apparent when playing music at low volume and during quiet parts of a song.
Testing Method:
i) Using headphones/earphones/whatever that plugs in the headphone port,
ii) Play music or other audio.
iii) Turn volume down to zero (0%)
iv) Listen for the noise.
Repeat method with no headphones i.e. with speaker, and put speaker up to your ear (very close). Try and listen for the noise.
my one x has the issue too.
As far as i know this is not an issue and it's normal, try doing the same thing with any other device and you will hear the same thing, may be hard to notice sometimes but it's there ( I didn't notice this on my HOX until i read your thread )
I do have this hiss on my one x.It can easily be heard when the music is stopped and this hiss continues for a small second!
It drives me mad as I tend to listen to music on lower volumes compared to others...
Sent from my HTC One X
if it is for 2-3 seconds and then it stops, it's normal, not an issue, due to a low voltage signal the sound chip sends to audio device (whether that would be a simple earphone, or a full support Bluetooth audio kit) to announce that the sound broadcasting is finished... (fade out noise)
Same here.
At 0% volume mine does not hiss, however if I play a song then pause it there is a faint hiss for a second or two then it stops completely.
Here's another one, plug the charger in and here the buzzing/feedback through the earphones when charging...

No, the problem that I'm experiencing and trying to see if others experience is whether the hiss is happening DURING the music. I understand if you listen to music at above 50% you most likely will not hear it during the music.
Yes, I have got the same problem and it is caused by very poor SNR of One X DAC or analog circuit.
It is very annoying for me, as I use sensitive IEMs and my old HD2 has not got this issue at all - I just find hard to accept that I have to hear audio noise in 2012 flaghsip device. There are some workarounds possible that can POSSIBLY at least partially mitigate the problem:
1. Use less sensitive headphones
2. Use some kind of attenuator, like:
http://www.ebay.co.uk/itm/Sound-lev...13488602?pt=US_Headphones&hash=item1e6f218cda
and increase listening volume at the same time
Issue confirmed. Could not believe that in this day and age I am confronted with such an obvious hiss on this top-of-the-line HTC phone.
Coming from the S2, I have not been impressed with the quality of the One X. I like the screen though, when I can't see any yellow spots, that is.

Will an external DAC help with this problem, if even usable with a phone?
Sent from my HTC One X
I probably should have said in my original post but yes I have the issue and noticed it....
Alternative was to use Bluetooth, I personally might get an APT-X adaptor thats portable so I can connect to my home cinema system or car stereo through the jack input....
I wonder if there's any One X without this problem, such as newer batches etc

If you can feed it a digital signal, then yeah, by all means it would help. I've not looked into it, I dunno if it's possible.
about 3 peoples said there it is normal so why continue this ? lol it have everything that make music,sounds.. its normal due to low voltage to earphones and there is currently no technology that can stop this noise...

I have a G2 running the lastest euro open rom and the issue is still there. Nothing has been fixed! Lets face it... They either don't want to or don't know how to fix it...
Hello
While I do not get a hiss I am getting distortion from the LG G3 in the left on earphone - I have found that it happens on the earbuds you get with it along with my Sennheiser, both have them inline volume controls. My Sony earbuds do not have the inline volume control and I do not get that distortion. All earbuds testing on other devices and working perfect. You can hear the distortion in say low volume parts of say the Man of Steel soundtrack.
Anyone else have this issue with distortion in the left?
Thanks.
For people who are "not sure" if they have this issue: play some music with rhythmic bassline, then go to Settings --> Accessibility ---> in hearing section move the "balance" slider to the right. Now you should hear the distortion in its clear form in the left phone.
... would be interesting to see how many have this - I would pop round a few shops this weekend and try out some demo units to see if they also have the issue - however I am moving so no time - Would like to know if everyone with the G3 has the issue or some.
Its not something you have to listen very hard to notice - something with a bit of bass effect - I notice it on Man of Steel soundtrack, 1m 12s in on the track DNA.
By the way is the same if you use in inbuilt music player or my preferred player PowerAmp, of course all effects are off. The media files themselves are flacs which I use in testing audio equipment, so I know the files themselves are perfect.
I have this too. But it also seems very picky about which AUX-cable to use. Ive tried 5 different wich I know all works well.. tested them both with another phone and my Nexus 7. With 3 of them the phone doesnt even recognize its plugged in, the sound continues to play though the phones speakers. With the fourth one I get sound but very noisy and when i rotate and wiggle the cable it gets more noisy and static. With the fifth cable I dont get any of that but the left channel is still a bit noisy at certain parts in the songs, just like you describe in this thread.
Do you think all this is related to the same problem or have I also gotten a phone with a bad jack?
Hey Dyln
You have come to the same conclusion I have come to. Really not sure whether to ask for a replacement and find I get the same experience (alot of hassle for nothing) - Just find its really funny about what headphones you use. I am not liking that my £50 Sennheiser earbuds for gym do not sound as good as my other devices - Is that a batch issue on the hardware side?, is it a software issue (like G2)? God knows !... just annoying as its otherwise a great phone.
Christopher.
Hi I have the same issue with a pair of Shure SE-846 (9 Ohm). Very annoying. Hope this will be fixes soon or I have to get an in-line resistor to increase the impedance. There is (almost) no noise with headphones above 32 Ohm.

I don't have hissing on mine, using the stock Quadbeats and iPhone5 headphones. I have the F400K Korean model. (I am familiar with the hiss as my old G2 had it (was fixed when I was using one of the Cloudy custom rom though).
Distortion and feedback in between songs playing in car with 3.5mm jack
I've just posted over here which is I reckon a related issue involving the 3.5mm jack....
http://forum.xda-developers.com/lg-g3/help/aux-cable-problem-t2802719
At the risk of repeating myself I'll just copy and paste in here too...
"I have a similar issue with the 3.5mm audio jack cable in the car.
Although i have tried a couple of cables and they do produce audio out of the speakers, I have a nasty problem whenever there is a gap between tracks, or when listening to radio if I pause it for more than 1 second.
It's as if the LG is cutting the power to the aux cable, so that when the music is restarted, or more annoyingly of all after EVERY song when played straight from the device, there is a nasty distorted feedback coming from the left speaker.....
Surely this is related to what the folks are saying over here...
http://forum.xda-developers.com/lg-g...music-t2804065
It never happened in my car with my Galaxy S4 or my Galaxy Note before that.
I'm seriously considering returning the handset as this noise is just not bearable - it's getting near a deal breaker for me.
edit: should have mentioned it also happens when an incoming call ends, the music cuts back in with a big old distortion/feedback."

It's good to know that there will likely be an easy fix. Even if that app has some compatibility issues, I'm sure a G3 version would come out.
LG G3 Hiss noise on left headphone
I did quite research on this issue.
Here is what I did:
Tried with 7 different high end - low end headphones. All having same issue on left headphone
My friend has the same phone, he is having the same issue
Went to Retail and tested 2 different phones, both having the same issue.
Tried with different songs, but the best songs you can listen to understand the noise is solo piano songs.
Try to listen this song: Ludovico Einaudi - I Giorni
If anyone has bluetooth headphone, I would like to see the test result. So we can understand if this is hardware or a software issue.
If bluetooth fails, It could be software otherwise most likely a hardware issue.
I thought this was a KitKat issue... so returning your G3 won't do any good. I experience this also. I'm not sure why Google hasn't made a fix for this yet.
Brilliant, thanks Online111; was meaning to pop round some retail shops to test out other G3's. Looks like it is a personal choose then if you can bear it or not. Was very nearly going to get a swap out.

I really like this phone, everything about it is great for me EXCEPT the sound quality. Anything that has to do with the headphone jack is an absolute disaster.
First off I have not experienced the dreaded AUX problem but I have experienced random pausing and skipping - as if I was pressing music controls on my headset - both in my car and on my headphones. I think a headphone jack is starting to wear?
Next I have experienced terrible distortion and static in the left channel, that was until I rooted and Installed Viper4Android. While the problem didn't go away entirely its much better than stock.
Im using my g3 with 3 or 4 devices....
My Acura's line in with Subs/Amps ect.
Shure SE846 In ear monitors
Fiio e6 amp (with the shures, sometimes helps sound quality)
Bluetooth to my Bose Soundlink
The flaws of the g3's sound output are noticeable on any of these, even the bluetooth soundlink and ESPECIALLY, on the SE846 direct.
I created this thread because I dont know what to do, its apparent I am an audiophile and care about my sound quality and youd think Id invest in some sort of MP3 player (I do have a Clip+ ) but I really enjoy using spotify. Should I buy a DAC and just avoid the g3s sound card all together or call and fight with LG and see what they can do?
Is anyone else having these problems? I have the Verizon Device.
I use Westone's connected through a Sony SB52. I haven't noticed any issue except that I like Sony's Walkman app better on my Xperia than LG's player.
I'm fairly picky about music quality and I haven't noticed any issues at all with my HD419s (the only headphones I have right now). Audio quality through aptx bluetooth directly to a car amp and polk component speakers is as good as one would expect too. No skipping or pausing with LG's app. Is that happening when your screen is on? Try turning it off, maybe it's a screen issue? Or maybe it's a glitch with the app you are using? The only problem I had with it was how quiet it was with headphones but the fix with root worked well.
There are several threads about the strange hissing sound - which I also got myself. LG has told me that they're working on fixing it and that it's a known flaw in the current ROMs.
I just got mine and I think this is the best sounding phone I have ever heard. Of course my expectations were very low after my experience with Apple and Samsung.
This opinion is coming from a very jaded HiFi gearhead so your mileage may vary.
The problem I'm facing..
There is noise+distortion+hissing during call
And when headphones are connected I cant understand or listen any thing I only hear wired noises..
Any fix guys ?
Dont know if its technical or software based issue
The sound quality has been noticeably bad for me using headphones also, bluetooth isn't too much of a problem and works fine.
I just got my headphone jack replaced free from LG (as it was doing the random skipping thing) - I quoted that it was a known problem (i mean look on XDA for all the threads) and as my phone was under warranty, i flashed stock firmware and sent it back - when i got it back in 48 hours it was replaced and working. They even cleaned the screen for me lol.
I don't use a headset, only headphones, and the quality is most noticeable on my sennheiser hd800s, but also on my beyerdynamic headphones. Install Viper audio and it improves slightly.
I got mine replaced today as well.
New phone bingo !!
I got my note 4 dev edition on Tuesday. I like to listen to podcast via pocketcasts and music through amazon prime music app, pandora and spotify. I notice at low levels there is an annoying hiss/ white noise that constantly is audible. I use these same apps on my iphone 6 plus and have never experienced this. I usually use yurbuds that direct the sound directly into the ears but it occurs with my old samsung earphones as well. (Verizon to cheap to allow them to include the earphones).
Is anyone else experiencing this? I tried to go into the play music app and use the equalizer but this had little affect. Is is an issue in 4.4.4 or could I have a bad phone or bad DAC??
I get the same problem as well with a Canadian Note 4 (N910W8). It's very annoying trying to listen to audiobooks or podcasts. Did not have this problem with the same audiobooks on Nexus 4. It seems like the hissing / static does not get louder by raising the volume so it's always present if volume is not muted and is very noticeable with spoken voice. Tried several players and it happens with all so it's not just Samsung Music with SoundAlive. I hope this is something that can be eventually improved and not "by design".
Are you plugged into a USB charger when you are listening?

I thought that might have been the problem as well but it sounds exactly the same when plugged in or not. It sounds like hissing and a bit of crackling after spoken words or pauses between sentences, very noticeable even at only 1 volume step from muted. Probably happens to music, videos and games as well but may not be as noticeable.
I've tried stock, custom roms, volume mods and Viper4Android and tried different players that I know use different playback methods.
I don't think there's a quick fix for this problem and we'll probably all have to live with it. Here's hoping Samsung's Lollipop update brings improvements.
Weird. I dont get a hiss at all unless its plugged into a USB charger.
Might be a hardware issue.
Turns out that it's affecting all 3 of my Sennheiser headphones but not the stock headphones. Never had a problem with these headphones on any device I had within the last 7 years.
It has to do with the low impedance of my headphones and the fact that the Note does not provide enough power to drive the headphones correctly. I went and purchased a 36ohm impedance adapter on eBay (from awaudio) and it got rid of my problem! My remote control on the headphones no longer work with the adapter but the microphone does. I've also got a 14ohm adapter in the mail that I've yet to try so I cannot currently comment on using more or less than the 36ohm I've got now.
I found the idea to try this reading through long threads in the Galaxy S3 forums so this isn't a new problem to Samsung. Many people have exchanged their S3s to correct the problem to no avail. The good news is that the problem was eventually fixed in a firmware update so I guess it's possible for the Note 4 as well but I'm not holding my breath for that.
I believe that the sound may not be quite as strong with the adapter but the ROM I'm using has the sound boost mod and is more than loud enough so I cannot complain. There may not be an easy way to fix this on a Verizon device if you need the volume as loud as with the stock headphones.
Night and day difference when listening to audiobooks or podcasts with low impedance headphones.
Power might be the issue, but I know a lot of others dealt with this and replacing ended up working. I think on the n2 the headphone Jacks were a bit loose but don't remember
