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,
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 haven't seen this posted about the Note. Does anyone else have a bad hiss when listening to music? Using Google Music and spotify, there is a definite hiss in the background.
I realize the Note's audio chip isn't great but I wasn't expecting this. Coming from the Captivate, this is really annoying me at the moment.
I hear it only in headphones
I don't hear it on the speaker or via BT. Haven't used the headphone jack yet.
Right, only on headphones. Quite loud and intrusive. I listen to my good quality in-ears at work for hours every day. I can't believe just how crappy the sound is on this otherwise fantastic device.
Ok, you got me wondering so I put on a decent pair of over-the-ear cans and spent 10 minutes flipping through a half-dozen channels of XM (128 kbps streaming). Then 5 more minutes going through several high-quality MP3s (variable bitrate with a max of 224 kbps).
No hiss, no background noise at all during the soft parts. Cranked the volume up to max, no distortion. Very happy with the results - much better than my last phone, the onboard sound on that sucked.
I'm on the stock rom, are you using something else?
For mere there's some noise when I'm not listening to anything, but I only hear it on my headphones.
In car Hiss
have not noticed it with headphones...but.....While using the car dock, any pause in the music whether it be on Pandora, Google Music, or just no app selected, There is a really annoying hiss/feedback through the speakers in the car. This is using the audio output connected to my stereo's AUX input.
It's just like a bad ground "whine" on a stereo...speeds up and down with the car. Never did this before with any other phone/device, so I know it's the note or the dock. I have not tried connected directly to the headphone jack on the note, I'll have to try that out.
Yeah the skyrocket did that too. I have a video up on you tube of it.

As stock as can be here. The hiss is most apparent at the beginning of the track when it starts playing but no music yet. As soon as the track starts playing, you can here it click on with the hiss.
Did I get a defective one?
I'm using a very good pair of in-ears (UE700s). I'll try to dig up some cans later to try it. Maybe directing sound directly onto the ear drums via in-ears picks up the hiss better (less natural filtering?).
Another thought: is there an internal amp volume/gain? Listening to the in-ears, it seems the media volume is very loud even at low settings and amps up quickly with each keypress. Maybe there is another sound tweak I can make somewhere.

A common problem if you are also charging - you are setting up a ground loop. You can add a ground loop isolator on the audio cable (big and clunky), unplug the power, or unplug the audio (and use BT in its place).

While I'm not a die-hard audiophile (I won't spend 10K on a sound system) I do consider myself to be pretty selective. Partly why I ripped my CD collection @ 224 and not something lower - I did lots of tests beforehand and still could hear subtle differences @ 192. Also why I rarely buy 128 kbps mp3s. Anyway, for better or for worse I just don't hear anything negative so maybe yours is defective. I will bust out some in-ear buds tonight and take another listen.

Often media players will have a separate volume from the phone's "media volume". Then there are separate "media volume" settings for BT and the jack. Then don't forget internal volume on BT headphones. It can take some fiddling to find the best combination.

I had the same thing with all my devices. Its just bad ground. That cable will get you set straight.
I never listened to my note with headphones, just with my car stereo with that cable. I hear absolutely no hissing or whining noise, just absolute beautiful sound and bass. This phone is mounds better than the Captivate.
Well, I retried some EQ/volume apps that I might has used recently to make sure there isn't any overboost feature enabled but nothing I can do to solve my problem. argh...
I never tried headphones in my Note with the stock sound equalizer. I had already installed the Beats by Dre mod in the developer's forum.
Zero hum whatsoever, and my happy hardcore sounds amazing.
I too have hiss from the headphone jack. I just returned my first Note yesterday hoping that the hiss would go away. It did not. I use mine in the car with an adapter that hooks directly to the back of my radio (JVC proprietary style).

Huh... I was about to return mine today but maybe it might be fruitless? Or maybe there is a large quantity with hiss and others without?
For those with no hiss, do you find the volume to be very loud? What I'm talking about is even at low settings, just 2-3 notches above silent, the volume is already pretty loud. My phone feels like the internal "gain" was set too high.
I know on my captivate, I could set the media volume to about 40% and still be comfortable. On my Note, it's about 20-30% if that.
Does volume of the note sounds real low to you compared to smaller phones???

No, it is TOO LOUD. just a couple notches above zero and some music is already getting too loud. This is with headphones not internal speaker.
I just got back from swapping my phone from the AT&T store. Both models (black/white) on display had the hiss. I decided to go ahead and swap and maybe a new shipment had an updated phone. NOPE, the hiss is still there.
I've used 3 different in-ears (couldn't find any over the ear cans) and also tested on a captivate and galaxy tab 10.1. It's the Note that is doing the hissing and very noticeable even at low volumes. Easiest to hear is right when you track begins but before the music starts.
I think this might be a deal breaker for me. I love this thing though. Especially irritating with spotify between tracks.
music end -> hiss -> soundless gap -> hiss 0> music starts
Anyone know of an app (probably one that requires root) that can adjust the internal gain like what voodoo sound did?
This older thread I just found (post #5) seems to describe my problem as well.

In order to quantify if this is hardware or not, try doing a factory reset (since you've returned your phone it shouldnt be that big of a deal).
Then, using the stock player on the phone (feel free to update Google Music or any other apps that came with the phone) see if you have the same hiss.
The factory reset is to determine if its possibly an app you installed at some point that is 'boosting' the sound internally without your knowledge. Sound boosting can create signal to noise problems.
Make sure your phone isnt plugged in / charging to anything (not plugged into a PC for example).
And try moving around to different locations, for example, in your house, try going into your front / back yard and see if the problem persists.
You also might try a different set of headphones and see if you have the same issue.
And lastly, if you plug in the headphones and reboot the phone, once the phone is fully booted, check to see if you hear any hiss WITHOUT any apps open?
As a side note, I just tested this (believe it or not, Ive had the Note for 3 weeks now and never plugged in headphones) using Seinnheiser studio HD 600 headphones (very expensive at around $600 for a pair and VERY power efficient) and have no hiss. However, the sound quality isnt all that great but that is a different issue.

Thanks for your helpful tips. Unfortunately, I've tried all that. Factory reset and all. As soon as the phone is ready to go, I listen to some music and hear the hiss immediately. Home or office, no difference. Not plugged in. Different in-ears. 4 different Notes.
I'm using very good in-ears (UE 700s, dual armature) and also decent SuperFi.3s.
Something interesting. Took a listen to a friend's good headphones just now and do not hear any hiss. Even if the media volume cranked up close the max, sounded fine, no hiss and listenably loud. With the in-ears, I can barely get half way up in volume because it becomes too loud.
Anyone here use in-ears? I know most prefer headphones or earbuds.
I'm going to try an inline attenuator tonight to see if that helps (if I can find it!).
What do you mean 'as soon as the phone is ready to go'?
As in, the instant you plug in headphones the hiss is there?
My guess is likely that the in-ear headphones are putting the sound right up to your ear drum and they likely are super sensitive.
The sound chip in the Note is not near to as good as the sound chip in the Captivate.
Im going to do a bit more experimenting with this as the only headphone I have are the seinnheisers and they arent exactly great for portable listening. I have a friend coming over tonight who has some very high quality in-ear headphones and Ill see if I hear anything with those.
So I have looked just about everywhere to see if anyone else has had this crazy issue and I can't seem to find anyone else who has.
The issue I am having is that when I plug in Beats headphones or portable speakers into the headphone jack, the audio is only output while I am on my home screen. If I open any other app, pull down the notification shade, or even let the phone sleep, audio no longer pushes through the headphones. It continues to be played but is not being output. Things get even more confusing when I put in Apple ear buds because the issue totally goes away. It only presents itself with headphones such as Beats or portable speakers.
I have had this issue on just about every KK AOSP rom I've ran (tried just about all of them) and using different kernels as well.
I have tried wiping everything and starting from scratch with a clean rom and the issue is still there. It's worth saying that the issue isn't on one single app such as Play Music or Spotify, but rather every app that outputs audio.
If anyone has any suggestions on how to fix this I would be very grateful. I am really a fan of the stock look and fly quite frequently so noise cancelling headphones are much preferred over Apple's.
Thanks for any help given!
EDIT: I'm also on the Verizon Note II
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?

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!

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"?
