Crackling and popping sound - Nexus 7 Q&A, Help & Troubleshooting

So I've had my N7 about a week and its almost perfect. The only real problem I'm having is sound. Whenever I'm playing music locally or streaming from Google play, ill get ungodly popping and skips in music playback. It only happens when I'm multitasking, so I know its not a general hardware fault.
I'm currently using paranoid android, latest version. I've tried different kernels, governers and schedulers but nothing seems to fix the issue. Tried disabling DSP Manager and wiping/restoring. It's hard to see how the device can get overstressed while playing music. My Galaxy nexus doesn't have this problem, and its not as powerful.
I've tried researching the issue, but all I've been able to find are complaints about the speaker. I'm not using speaker and have tried several pairs of headphones.
Anybody got any ideas on how to fix this?

Bluetooth music skips on high bitrate songs

Any workaround for this besides downconverting those songs I have a motorola T505 bluetooth fm transmitter. I'm sure its probably just a hardware issue on my T505 but skipping songs is as annoying as converting all those songs. Thank you

This seems to be happening with all my music, but most of/not all the time and not for a long period until recently. Which leads me to believe it's a performance issue somewhere and thinking I either need to try a different music player besides stock...or do something like logcat and try to discover what it is. I've tried many other variables for things which steal memory/CPU and nothing helps. Any tips appreciated! I run rooted stock EC05.
ETA: this happens on both my stereo BT devices, but is worse with the headphones (Sony Ericsson AW600) than the Blackberry Stereo Gateway. I get a skip every few minutes of about 1/2 a second at its most regular. Last time it appeared "fixed" was when I cleared all system caches and rebooted after a batt pull, but it returned again. :-(
Skips happen regardless of bitrate or player with my 2010 Mazda built-in Bluetooth as well. Quite annoying; I haven't narrowed down to whether it is the car or the phone though.
Of course, I get skips and pops using regular wired headphones. I hope we get better audio drivers with the GB update.
On the same boot today as yesterday, problem is temporarily gone. Only thing notable I've done was disabling and restarting BT and I don't know if that actually has any effect. It also never seems to happen while streaming audio or playing with no BT, only while playing it from the memory card using BT. Weird.
Thiss has been happening since I had a moment and I had the same music library and the same songs skip it never happens with tune in either

Just thought I'd chime in on some random recent bluetooth experience. I jog and typically hold my phone in my left hand (I use a Motorola S9 headset). The playback is fine (I use MortPlayer Music). If I move my phone to my right hand I get skips. I swear.... it's weird yet reproducible. ha.
When using my in car T505 I get no skips using any audio app.
I use a T605 in my car as well as T305 earphones. I would rarely hear a pop or skip. Now with ec05, i hear them all the time. really bums me out :'(

I have the same issue. Only happened since i asurion'd my original phone wen it was stolen... used to run eb13without issue, but with ec05 skips all the while

this seems to be a very BIG issue for anyone using bluetooth for music. can anyone confirm if this is present in any of the CM7 alpha builds because that is my only hope left for the epic

[ISSUE] Speaker popping DURING audio playback

Before you all yell at me for making another thread about this (I know one exists, that's what I originally found when I searched), this is a different issue.
I'm sitting here in my office at work playing music off my TF, and everything goes well for a while. Then about 30 minutes in, the speakers will start constantly popping during playback. It starts out softly, then gets progressively worse (to the point where it sounds like a dirty record).
However, the first time it happened, I held down the power button and rebooted the TF and that fixed it. Then about 30 minutes later, it started happening again. So instead of rebooting, I decided to try force stopping the Music app (I'm using Google's Music) to see if it's a software issue. And boom, the popping is gone after restarting Music. Weird. Because it sounds like it should be a hardware issue... but restarting the app making the audio seems to fix it. Next time it happens I'll try just opening up Youtube and seeing if it persists.
Anyone else getting this? I'm on stock un-rooted 3.1.
Hey, I seem to have this problem as well,
and only in the Music App.
I'm using headphone to listen to music,
and it just happened about 5 minutes ago,
I decided to unplug the headphone and replug it and it seem to fix the problem,
and then when it happened again, I switched to the Youtube app immediately and the sound was perfectly normal in Youtube.
So I'm suspecting its actually the Music app's issue.
may I ask if you are listening to music you stored online or from your device?
Are you streaming the music? Using any apps like equalizer or volume+?
Also happened to me today for the first time...and I am using volume+
I guess ill turn it off if it happens again and see if its that.
This happens to me when listening to music and the transformer sleeps, it takes a good 3 minutes then finally changes tracks. Once changed though I get this cracking nose also.

Same thing happens to me only when listening to google music. Will play normally at times, then popping will suddenly happen. I've listened to Squeezebox streams on my TF for extended periods with no popping, so I also suspect it has something to do with google music.
It would be nice to narrow down the cause and come up with a workaround.
used to have this problem when using older version of thumb keyboard, the typing sound produced this cracking noise. but fixed when I upgrade the thumb keyboard ;-)
+1 here.
Headphones, using Music player. I'm not using any special other apps to boost volume output. My headphones work just fine with any other device.
Unplugging and reconnecting the headphones seems to fix the issue. I haven't tested to see if this is exclusively with just the Music app or not.

Same issue, unplugging headphones fixes.
Running an OC kernel w/ Voodoo Sound, and Prime 1.4. Kinda points to an issue with software, I don't think i can blame the Player, more like the drivers/OS. Getting into a grove coding, i left my headphones on with no songs playing, and there was still an occasional crackle.
Really bummed, because this is a sweet music playback device with quality headphones and an amp'd signal.
Update: Flashed Asus 3.1 with CW Recovery mod (http://forum.xda-developers.com/showthread.php?t=1112527) and popping gone. Still running OC kernel.

Poweramp hissing noise

Got a question to those who using Poweramp. are you guys hearing static hissing noise while playing mp3 with poweramp? Read it somewhere else said it could be hardware grounding problem, but that's probably wrong because I can't hear the same hiss in the stock music player. But the stock player sound is damn flat when playing music
any help would be appreciated.
I got the same hiss sound in MX Player on one of the custom ICS roms. Can't remember which one. Went back to Stunner.
On any custom rom?

Nope, no poweramp problems here with headphones or with BT connection to car audio. Rooted on stock ROM.

I have never touched the configuration in poweramp and I have never had the slightest problem, even at + 10db with voodoo louder.

The hissing noise is normal regarding the Galaxy Note. It's there with every player.

Hi, try to disable the direct volume control under settings-> audio engine-> advanced tweaks

As far as I know hardware and software are the same for every note. So it should be there. Naturally, some people won't notice it. That's just the way it is.
That's total BS. I have never experienced any hissing either with Poweramp or stock player. I think there would a lot of very angry Note users if this was the case. I previously used a Rockboxed 5th gen iPod with an ibasso amp and now use the Note as my primary player as the SQ is so good!

Poweramp closes after two or three songs for me every time. It beeps four times, freezes up and needs a phone restart to get going again. Very disappointed after paying for it.

It freezes here too sometimes.. Have to report it to the developers...
But what is wierd is bluetooth audio stutters alot sometimes and nothing can resolve this but a reboot. Changing the music player doesn't help neither...

No hissing here, but i'm using PlayerPro. I used PowerAMP before but i can't remember hearing any hissing.
thx for the input guys. problem turn out to be the dspmanager, i totally forgot it is still there in my note, and still activated with it equalizer. I turned that off and it's all good now. Probably that's the reason I am hearing hiss in poweramp but not in stock player.. :x

Never had the first freeze or hiccup from poweramp, either on my xoom or on my note. Listened to music in my truck today for 4 hours straight (car stereo via BT from note) without any glitches, and that has been my experience with PA for over a year now (incl xoom time). Perhaps try uninstall and reinstall, then if that doesn't work look for potentially conflicting apps... don't think PA is the ultimate cause of your issues.

That happens to me too.
Although, it is more random for me. Sometimes it is after 30 minutes of listening.
I get the beeps though.
Also, sometimes it stutters a bit and then beeps and stops.
At first I thought it was my BT headphones not working, but other sounds come through fine, so it's not them.
Sometimes PowerAmp will still show the pause button (ie, it looks like it's still playing), but if you press it, nothing happens. It doesn't change appearance and it doesn't start playing again, no matter how many times you press it.
I have to force close it through the application manager to get work again.
I only just started using PowerAmp about a week ago and bought the full version because I liked the EQ and the appearance on the Note, but I might have to go back to WinAmp.
I'm on the latest stock ROM, with root.

i see you found it was dsp manager...i've noticed it too..but only in certain scenarios....
i get this when i'm plugged into some USB ports to charge on various work laptops and listening to music...and also some power inverters...but this ONLY happens to me at work when I'm using my note in the truck and charging (as the laptops would be plugged into the same inverter I get the hissing/buzzing sound from if I plug directly into the inverter)....
pretty sure it's just bad ground or dirty power in the work trucks though...

@duckettmarc
i haven't experience the closing issue either....i've listened to poweramp for hours on end, hundreds of songs without crashing...where is your media stored? external SD? either way, I would guess either the storage area you have your music in, or your actual music is corrupted....or maybe some instability if overclocked, undervolted, or with the ROM you use...

No its not. Check the according threads discussing the notes audio Chip. As soon as you plug in your headphones and the Chip Starts working there is a hissing noise.

Re-read the according threads, it doesn't happen on every note.
Nothing to do with the M1CN2
I'm having the same problems. The thing is, it only started happening a few months ago when they brought out a major update...

Audio lag with Bluetooth Headset

I have a terrible problem. I'm proud owner of some Sennheiser MM550-X Bluetooth earphones/headphone and have problems while watching movies from internal memory and external sources like streaming youtube or from my NAS.
The audio has a terrible delay of something around 1-2 seconds.
Makes me wondering. I thought nearly every device supports apt-x for Bluetooth audio... Seems like aosp based devices didn't.
I google a little bit around and seeing hundreds of posts from people having the same problem. It seems to be a known issue since ICS but it is still present in JB. Google didn't fix it.
The problems seems to be caused by the integrated chip which handles wifi and Bluetooth together. If both is enabled the delay is much higher... It also effects games and system sounds like the tick sound from keyboard etc.
It also looks like some devs found possible fixes for that. Think I saw a post on transformer Prime forums from team eos who might have fixed that.
Is it possible for anyone to fix this problem. Are there any Bluetooth drivers to play around with?
I also noticed the same issue on my HTC One X which is also tegra3 powered but it is not so hard like on nexus 7. On iPod and ipad I have no delay issues, which proves that this is an android bug.
For anyone with the same problems I found out that dice player from play store fixes that issue for me for watching videos. It also have the option to adjust the audio delay manually. But this is only for watching movies... The system sound delay still persists.
Thanks and regards from berlin

AOSP roms simply don't support APT-X. you need to use a stock rom on a phone that supports it (one-x, gsIII, note 2, etc)
So the problem is - you're not getting apt-x.

Crackling when skipping tracks on Google play music?

I've had my N10 since release and have been running CM on it flawlessly. However I have noticed recently that when skipping tracks on Google play music that there is a slight crackle in between tracks? It doesn't always happen but I am curious if anyone else has experienced this?
It is very quiet. Have to be in a quiet place to hear it.
Edit: I think it has to do with the DSP wpp in cyanigen. Seems to go away whenI turn it off,
