[Q] Music stops when app switching.

I've asked this question before but there were no replies.... I hope this time I'll get some pointers and re-phrase my question better.
I'm using the GSM Galaxy Nexus 4.1.1
Sometimes my music stops playing when switching apps or pressing the home button to return to the home screen, it doesn't happen all the time, but very troublesome when it does. It happens usually just right after unlocking the phone from sleep. I'm using the stock music player
I've noticed that this issued happened to Android phones as well, I tried to update the stock music app, and switched kernels. I don't know what else I can do. I don't recall encountering this problem back in 4.0.4.
Any help would be appreciated

Give us a bit more info:
1. What music app are you using? If it's an app that can both play local media files and stream, which are you doing?
2. Are you playing your music through headphones, the internal speaker, or Bluetooth?
3. If headphones, have you tried other headphones? If Bluetooth, how far away are the devices?
4. Which ROM and Kernel are you using?

I said I'm using the stock music player, Play Music.
I'm playing music through headphones.
I am sure that this problem is not because of the headphones
I'm using the stock 4.1.1 ROM JRO03C. This problem happend on both the stock kernel and Franco Milestone 5

Are you running any other memory hungry apps? Sounds like your music player is getting killed because the memory is needed for something else.

I've had this happen in two instances, so hopefully my personal experience will help you.
The first time, it ended up being a faulty cord in my Nokia Purity HD headphones, I bought a new cord and that fixed my issues.
The second time it was because I was attempting to play music, that I had downloaded in Spotify, but since I was in a crappy coverage area, it would pause the music every time I lost a data connection, even though the music was stored locally. Switching Spotify to offline mode fixed it, so you might try switching to offline only mode in Play Music.
Even if you don't think it's your headphones (for example, you tried them on a PC and they worked), you have to remember that phones have many more contacts inside the headphone jack, used for the media controls in headsets (headphones with buttons and mics), so if there is a short in your headphones that makes the phone think you're pressing the "Play/Pause" button, it wouldn't show in your PC, because most if not all PCs lack this functionality.

[Q] Audio Sputtering and Popping on Spotify, TuneIn

Hello all,
I love the audio quality on CM, however ever since using it on my Verizon Galaxy Nexus, the audio on Spotify has constantly popped and stuttered and sputtered and whatever other word you want to use when playing through the headphone jack.
I feel like I've tried everything outside of switching ROMs. Tiny Kernel, Franco Kernel, CPU Governors, etc etc etc, doesn't matter.
I've also done search after search after search, and I feel like I'm completely alone in having this issue. I can't find anyone asking about this anymore, now that Spotify claims to have fixed it in an app release months ago (which makes me think it isn't necessarily Spotify's fault, but who knows).
I should mention that this does not happen with Pandora or Songza, for instance. Only Spotify and TuneIn.
Of course, it doesn't seem to be a coincidence that both Pandora and Songza process the audio in some different way from Spotify and TuneIn, since normal use of CM's DSP Manager has no effect on those apps but does work on Spotify.
So, is there anyone else out there who has this issue with CM (or other ROMs)?? At this point I'm just hoping there are others out there who have had this problem just so it isn't an "only my phone" issue -- because those ones have no hope of being fixed.

I have the same problem, running stock 4.2.2 on my Galaxy Nexus. I think it's a device problem, not an app/background process problem.
I don't use TuneIn so I can't speak to the quality of its streams, but I have used Rdio, Slacker, Pandora and Google Play Music and they all play flawlessly.
ONLY Spotify plays audios with occasional snaps, crackles and pops, like a bowl of Rice Krispies. Some songs will play without a blip, some with a few, some with many. The songs are not interrupted...just marred by this defect. And it's never the same way twice with the same song.
It happens whether the song is streaming, or playing locally.
My guess is that the Nexus has difficulty playing Ogg Vorbis files, which is the format for Spotify streams and downloads. As far as I know, the other services I mentioned stream in AAC or MP3. While the Nexus supports Ogg Vorbis, it appears it does not support it very well. I'm going to test this theory by transcoding one of my Apple Lossless audio files to Ogg and then uploading it to the Nexus. My hunch is that it will demonstrate the same issues.
I guess we should consider ourselves lucky; before Jelly Bean the Nexus suffered from more dramatic playback problems. Do a Google search on "Music Stutters when playing long files and screen off: Galaxy Nexus" and read through it. There are a couple of posts that deal specifically with Ogg playback.
I've decided to live with it. I've been hopping from music service to music service trying to find the right one, and I always come back to Spotify. As long as the issue doesn't become more severe, I think I can re-program my brain to tolerate it.

My theory was incorrect. I used XLD to transcode Boston's "Hitch A Ride" from Apple Lossless to Ogg Vorbis (VBR, quality 4.0), then put the file on my phone. I used Winamp to play the file and it played beautifully.
So I'm thinking there's something specific with Spotify's encoding that the Nexus doesn't like.
What's odd is that I have run Spotify on other mobile devices and have never had an issue. That's why I have trouble putting the blame on them.

OP, after checking many Google leads, posts, etc. I believe--for Spotify anyway--I have found a way to stop (or at least greatly reduce) the Rice Krispies.
If you have Google Play Music on your phone, make sure it's fully updated and then launch it.
Within Play Music, go to Settings, then select Equalizer.
Turn the equalizer on, select the Normal preset, and move the Bass Boost and 3D Effect sliders all the way to the left to turn them off...unless you like them on.
Back out of Google Play Music to the home screen, then launch Spotify.
Go to Settings within Spotify, choose Audio Effects and verify the Equalizer is OFF in that app.
Using this combination of settings/conditions, I have heard just a couple of pops over a string of a half-dozen songs. I'm keeping my fingers crossed that it lasts.
I'm guessing that having the Google Play Music equalizer on, some additional processing is taking place that alleviates whatever is causing the popping to occur.
Good luck!

Bluetooth A2DP stutter cuts out while streaming music

I have noticed since I upgraded from GS3 to Note 3 that when I am streaming music to my car stereo the audio will skip or stutter. The song continues to play but the audio cuts out for anywhere up to a second or two. Has anyone else seen this or resolved it?
I have seen some posts that say turning off WiFi fixed it but I still get the skip, if a little less frequently with WiFi turned off.
It seems to go away if I set the developer options to keep the screen awake while charging. So it seems like the CPU clock may be too low during sleep to maintain everything else it is doing as well as audio streaming.
Any feedback is appreciated, thanks!

This happens to me too sometimes. It seems worse when I first start streaming & then it calms down a bit. But it still occasionally skips. I experienced this on my note 2 as well though, so I don't think its an exclusive issue to the N3.

This is happening 4 or 5 times per song, so it is quite annoying LOL

Stock ROM? Stock Kernel? Need more info from both of you.
Sounds like the CPU might be dropping too low when the screen is off, causing the stuttering. You could try a custom kernel with a higher screen off frequency.
Used to happen on my S2 and this was the problem...

Full stock, I believe that is the problem as it is pretty much resolved when I leave the screen on. Still testing this here and there to be sure.

This has happened to me on every rom & kernel I've tried. Which is pretty much all of them for the N3, and everything from stock to CM on the N2.

I have the same problem on my GN3 international version and yes leaving the screen on WILL solve it. However, that's not a practical solution.
Try this, download Poweramp, go into settings, audio, advanced tweaks, set the audio buffer size to Large (+250ms) and audio thread priority to +2
See if that works for you. If it does, then buy the full version even though I like the timbre effect and bass on the stock music player but this is the only solution, so far.

What headunit? I run Kenwood KDC-X995, and never had an issue with it cutting out. THe headunit wouldn't display track info though. The way I fixed this is connecting via the Stock Samsung media player., Everything has been a dream since

I had this problem and it just went away after a few reboots and some time. ..

A2DP loss
Note 3 Owner here. Rooted with stock ROM and stock kernel. (T-Mobile)
Experiencing intermittent Bluetooth audio loss as well.
Just contributing to the list.

BTW, what player are y'all using? In power amp there is an option for keep service awake if music.stops while.playing with screen off. And there is also option to use a wake lock also. I am not having any problems nor have I ever so I can't help. The only other suggestion I have is maybe your radio Bluetooth sucks. I went through a period of testing many Bluetooth headset and receivers a couple years ago. Needed something good to listen to my music while I rode my bike. Many of the Bluetooth I tested were very sensitive to the bumps and vibration while riding hard on my mountain bike. The only solution for those were to put receiver right next to my phone. Being in my pocket was too far away or something. I ended up sticking with Sony mw600 as all purpose. It could take any headset, and I was able to use it as a receiver in my truck as it didn't have Bluetooth. Now I also have a Honda civic with built in Bluetooth and all is well. My Sony mw600 oled stopped working though so in on lookout for a nice apt x receiver.

I am using a Sony DSX-S300BTX and have had no previous issues with my HTC Sensation 4G or my Galaxy S3. It only started when I got my Note 3. I use Google Play Music with the All Access service.

Just an update on this. Over the weekend I did a factory reset and this time I did not let it restore settings and apps from my Google account. I went through and installed all the same apps i was using before. And so far I have only noticed 1 stutter/cut out since then. And if I am correct, this only happened when I was leaving my house and it switched from Wifi to 4G LTE on the stream.
Will continue to monitor and see if the issue comes back. But so far I am rather happy.

Trying this recommended app/setting combination, and hope that the skipping stops on the A2DP connection in the car. *crosses fingers*

I came from the Note 2 to the Note 3 and I'm fearing that it's 4.3 that is causing the bluetooth intermittent issue. Whether or not I stream from Pandora or my music player, I get the stutter. Doesn't matter what ROM I use between hyperdrive and beans too. Someone said it could be the adblock that is causing the stutter but I don't have that installed at all. Getting pretty frustrating.

Ended up not working for me,...but keeping the screen on did seem to eliminate the skipping.
Wonder if there's anyway to force Bluetooth not to sleep,....

I ONLY get the stutter when using the stock music player. It never happens when using, for example, TuneIn Radio.
I exchanged 2 Note 3's. The first one had the stutter problem so I returned it. The second one had NO stutter problems but overheated from time to time, exchanged as well. The third one doesn't over heat but, unfortunately, has the stutter problem. So, I just gave up. The PowerAmp solution works for me, though.

Sorry to hear it didn't work for you.
Someone mentioned increasing the minimum CPU frequency and that would solve it. Try upping it to 400Mhz see what happens but this will definitely drain your battery more than usual.

The same thing happened to me on the note 2.... actually the n3 isn't as bad as the n2 was. Fwiw
sent from my ??????? note 3?

SO I have started to notice that it isn't actually the stream stuttering, but a short disconnect of the bluetooth. I noticed that when the music cuts out, it also drops the media connection to my car stereo, in that the artist and song title disappear until the connection comes back. Seems like a bad bluetooth stack or something as I tested a Nexus 5 and do not have this issue at all. And I never had a problem on my GS3.
Hopefully the 4.4.2 update will resolve this issue. Whenever that may be...

I have this problem as well, (stock rom rooted, stock kernel) I use power amp. now however I cant stream my music through bluetooth at all, but when a call comes in, it streams. Doing a little digging into my phone, my N3 seems to think im in a call, and only plays my music through the speaker for your ear. it only started a few hours ago. even when I am not connected to bluetooth, it still plays music through the same speaker. tried uninstall reinstall. I did update apps earlier when I got home (ove wifi). once they were done, that seems to be when this issue started.
any help/suggestions?

[Q] Bluetooth audio issue on stock 4.3

Really annoyed at myself for taking the upgrade to 4.3 as now I have an issue with bluetooth that I cannot figure out. Bluetooth audio to my reciever was perfect before but now it has the same problem no matter what app i use (tune in, xiilive, standard media player etc)
Basically the phone sends the audio but the speed varies. Like a song will play normal speed, then maybe speed up for a second, then the audio cuts out for half a second and its back to normal again. This will stream fine for maybe 5 seconds and again, any audio will speed up a bit, and cut out. Its only happened since 4.3. Anyone else have this problem or know of a way to fix it?

Well a bit of an update on this. It turns out it doesnt skip with music thats on the phone. So the stock media player and mp3s etc stream totally fine. Its just with audio that is streamed via apps like winamp, Xiilive, Tune in. They all have exactly the same problem as described above. However, the only way I can get it to stop skipping and run normally is if the screen is on and I am in the Wifi networks setting page. Its fine then, until the screen goes off, then it starts to skip again. This is so annoying now. Is it an android issue? Not connected to bluetooth through normal headphones or the Note 2 speaker, all these apps are perfect.

Poweramp Buzzing?

POWERAMP MUSIC PLAYER
Please forgive me for starting a completely new thread on an issue (Bug) that may or may have not already been fixed. I've searched all of XDA and Poweramp forums for solutions but have not found any. Hopefully this is not just my phone suffering from hardware failure and simply just a Poweramp glitch or bug that seems to effect the galaxy nexus. If it is just my phone, well I will ask the moderators to just delete this thread and my apologies. I will just throw my Gnex in the garbage and use my old Samsung Vibrant.
Now with that being said, is there anyone who is currently using Poweramp as their primary music player on their GNEX running 4.4 or any version of android for that matter? If so would you mind sharing what your Poweramp experience is like. In other words is their any BUZZING or SKIPPING that occurs when you are performing common tasks such as browsing the web or checking email or whatever the case may be. When I say BUZZING I really mean BUZZING, like someone being buzzed in to enter a door or like a buzzing bee except much louder to the point where it may cause some serious hearing problems. I don't mind the audio skipping or popping it is just that damn buzzing that is literally giving me a headache. Now you may say...well why don't you just try another music player? Well I have tried just about every single music player available on google play and none of them, I repeat NONE OF THEM come close to the audio quality of Poweramp (take it from me I am an audiophile). I have contacted the poweramp support team and they told me basically to F-OFF because they don't support custom roms other than Cyanogenmod. Well I tried CM11 with stock kernel and the problem still persist so no luck there.
Device Info:
Samsung Galaxy Nexus i9250 GSM
Currently running the latest build of Vanir with latest SmittyV kernel (Stock or custom kernel doesn't seem to make a difference)
Default kernel settings
Default Poweramp settings not using Direct Volume Control or an external DSP (Audio Buffer Size or Audio Thread Priority settings don't seem to help either)
Buzzing only seems to occur when using headphones, it doesn't buzz when connected via bluetooth speakers but skips (really don't mind).
Again this buzzing ONLY happens when "Multitasking". Listening to music and browsing the web seems to happen almost instantly. When the phone is in standby with music playing...no problems at all. No buzzing,skipping or popping noises.
I've tried just about every rom and kernel combination that is currently in development to try and solve this issue but have had no luck whatsoever. Other music players mainly Player Pro with the dsp pack seem to have this exact same issue. Player Pro without the DSP pack works perfectly fine but there is no gapless playback support so that's not an option. I am on the verge of just giving up all together and using my Vibrant as my "daily driver" while I save to buy a N5 someday. But I am not quite ready to call it quits that's why I ask my fellow XDA users who are currently using Poweramp Music Player for their help.
What ROM and KERNEL are you using?
Kernel settings? Default or custom Settings?
Poweramp settings?
Please help.
