Hey guys,
Have searched a while, but found no solutions for this, so here goes.
Have stock Galaxy Nexus with ICS 4.0.1, build ITL41F, installed Google Music v4.0.9 (with online sync).
Music is synced with google's online music service (even though I'm in UK, worked-around US-only restriction), and plays nicely when the screen is on. Once I switch the screen off (press power button), one of two things happen:
- if sampling rate of a song is below 48,000 Hz -- everything continues as normal.
- if sampling rate is 48,000Hz and up -- every one/couple of seconds music stutters, and jerks. Feels like I'm listening to dusty ol' record!
The 48kHz part is my theory, compared a few mp3s that stutter and some that don't. This seems to happen irrespective of bps rate and other parameters (albeit haven't checked all).
Few people on the forum with similar symptoms (on other phones) suggested it has something to do with cpu throttle during sleep, and that by forcing it to higher frequencies during sleep this could be solved.
Installed setCPU (which required rooting) and forced phone to 1,200MHz in sleep as a trial, and the songs still were stuttering.
Anyone with a similar experience?
Prime suspect would be google_music.apk which is in beta i believe, and... well, i guess then I'm out. What do you guys think? Any idea what might be causing this?
This is my first android phone, so I'm not sure even how I'd go about submitting a bug, if that's indeed the beta version of music at fault here. Any pointers?
Ta,
Dan

That, is weird - because I am facing this with Winamp so I've switched to Google Music to play my music.
Does anyone else face something similar?
Can you do me a favor and play something you know that stutters, and then try it over a bluetooth connection.
I'm curious if this is also related to the static I get when the screen is off and output is analog outputs - digital (bluetooth) works fine.
same here with poweramp... switched to googlemusic... now i have only stutters over the phone speaker..
Same thing happen to me with google music and pandora. Thought it was the connection.

I get the same using the Music app (have WinAmp but doesn't seem to integrate with the lockscreen so don't use it) as soon as the screen goes off (either timeout or manual) you can hear the music slow down and start to stutter, tap the power button, screen comes on and music goes back to normal.
Have noticed it's not all songs, but have't looked into the differences between those that do and those that don't.
Are these locally stored songs that this is happening on? So far so good here but I have been streaming from the Google Music cloud.. I wonder if the CPU is struggling during the underclocked sleep condition with local files that are high bitrate...
Mine are local files, not tried from another source.
I've used both, streaming from Google cloud, and when songs are available offline in the music app -- still stuttering. Haven't tried any other method though.
As for trying to stream over Bluetooth, haven't got any speakers/earphones that could receive the stream at home. Going to try my luck with a local pcworld, if they let me.
I haven't had any problems with Google Music stuttering while the screen is off, but I have had it crash frequently while listening to music and multitasking. I experienced a similar problem with Rhapsody as well.

totally true! thought my phone was a lemon at first.luckily i didnt return it.
yep having the same exact issue. on speaker its just fine. when i plug in headphones or aux to car stereo and screen goes off it stutters / skips or whatever you want to call it.
Turn the screen on and its fine. However doesnt happen to all music. This was streaming from google music for me.
I'm pretty positive you guys have same exact problem as many other people. So far no one has take my suggestion of playing those same songs that stutter, and play them over bluetooth. I bet you don't get any more stutters. I think it has to do with analog outputs vs digital. To output analog, the phone has to use the DAC (digital to analog converter). When it outputs over bluetooth, there is no conversion, and the music is in digital form and transmitted in digital form
If someone can try this I would appreciate it. And you'd be helping everyone find a common denominator in this problem.
Also be sure to star this bug on google code http://code.google.com/p/android/issues/detail?id=22444#c6
Can someone post an mp3 this is happening to them with? I have a ton of them and I have not seen this problem yet.

Didn't I PM you a link the other day? I thought it was to you. I didn't click the box to save it to my sent box so I can't just look it up :[
Circling back. I recreated the problem with luxferro's 48KHz mp3. Seems whatever happens on this phone to play mp3 with the screen off cannot handle that sample rate. Any 44.1KHz mp3 works fine.

There was another thread like this. The current workaround is to enable the Equalizer for Google Music. You don't have to actually use it (leave it on default) but this solves the problem.

I guess with the eq on its forcing the CPU to get involved even when in low power mode. Unfortunately I believe that was causing other issues with crashing. Since I don't use 48KHz mp3 I'll leave it off.

For poweramp try settings... Audio engine.. Advanced tweets and change the audio buffer size.

Having the EQ turned on seems to work, just set it to flat and turned the 3d effect down. Guess it'll use less extra battery than using a 'keep awake' app like I was doing.
It could just be my phone, but has anyone noticed their music sounding like it have really really small breaks in the sound, almost like the music is crackling? I've even found this when listening to my Sirius Satellite Radio app.
Though I may have found a fix, at least for the music. Originally my music was 320bit and i had just copied a few songs to my GN. When I started to listen to the music i would get crackling like sound or where the music would have almost a stuttering factor. Well i was getting annoyed enough with the crackling I almost went back to my MP3 player. Though I decided to try it one last time but i wanted my entire playlist. Now my playlist was about 200 songs and across many directories so I wasn't going to try search the whole thing for individual songs. Using winamp I copied them all into one directory, unfortunately when Winamp does this it converts them all back down to wav files so I had to reconvert them.
My software for converting back to MP3 is older and only able to convert up to 256bit. I was thinking it was going to be just as annoying, but low and behold my music plays without a glitch, or crackle or break or what ever.
It's almost like the phone can't handle the higher quality of music. Now again this could just be me so I thought I would ask. Unfortunately my Sirius Satellite Radio app still crackles.
Anyone else find this?
also if u have used an app like volume+ to increase your speaker volume, or modify your volume that could be the issue
Good thought, though i never actually got around to installing the app so we can eliminate that as a cause.
Oh no, lossy to lossy transcoding! Those poor files.
I haven't had any issues playing 320kbps MP3 CBR or MP3 V0. If anything they sound better than on my old iPhone 3GS, especially with DSPManager.
Do they play without any distortion on your PC? Are you using the same headphones?
Perhaps playing around with the equaliser settings in DSPManager would improve the output.
Have had the same problem but only with one album so far, it is 320bit but I also have other albums at 320bits that play ok. Strangely the problem doesn't occur if the screen is on!
Give me to this weekend and let me hoot the phone up to my input on my PC maybe i can let you all hear what I hear.

I would agree too if I had actually installed volume+
I don't think it's to do with the bit rate as such but the encoder, or at least the encoding settings, that you used. Almost all my mp3 are in 320 kbps, CBR and VBR, and they all play fine.

the phone seems to clip a lot when the volume is at the top two levels. sounds bad. setting it to 3rd highest level or less makes it sound normal and smooth
Not sure if they fixed this with 4.0.3 yet, but it's a known issue that any SAMPLE RATE (not bit rate) other than 44.1KHz can cause stuttering when the phone is in screen-off low power mode. Some EQs that cause the cpu to work have been known to fix it. Also changing the buffer size in PowerAmp has also I think. There are a few threads about it. I have recreated it with another persons 48KHz sample rate mp3. All mine are 44.1KHz and I've never had a problem with any of them, they all sound fantastic.

There have been a few threads about static, clicks, pops, etc... but nothing that really helped me figure out if i'm having a problem or not.
I have a stock GS3, purchased relatively early - 7/2 - from best buy.
I'm not happy with the audio playback quality, specifically when compared to other devices, like my iPod or old iPhone 4 that i had before this.
Either using the stock Samsung app, or using PowerAmp, which I've purchased... with all file formats... mostly FLAC, but also m4a, mp3...
Using any of the headphones i've tried... beyer dt1350, ety hf2, apple in-ear, etc... (not junk)...
The sound quality of music playback just doesn't seem "clear" to me... not any really blatantly loud static or distortion, although sometimes it is worse than others... occasional clicks, pops, etc. But mostly, just a lack of clarity... which could possibly be a constant mild static or distortion on the output.
Is anyone else experiencing it this way? Am i just being to sensitive to a different sound signature of this device vs apple's devices? I don't think so.
I'm 100% comfortable with the quality and integrity of my music files... i have a ton of them, and they play back fine on all of my other devices.
What else could it be, before i have to send it back to samsung and be w/o a phone for a week? best buy already won't exchange it for me, as i'm beyond my 30 day window.
help!
I know exactly what you mean, I'm very particular about my sound signature as well. I find using an equalizer to work wonders. But i have noticed that some equalizers dont work at all will the stock rom when listening to on device music with Google Play Music.
Have you tried using an equalizer or even installing Awesome Beats?
This is a development forum for custom OS and software... If you're completely stock, maybe you should take that up with Samsung or try some of the nice modded software...
Hello,
There's one function on Android crucial to me that I have yet to find a perfect solution for, and that's variable speed audio playback. I'm a big audio podcast fan (using the excellent Pocket Casts app), and to get through hours upon hours of podcasts I like to play them back at a faster speed than normal. 2x speed, for example, sounds absolutely fine (not quite Alvin-and-the-Chipmunks fast) and as you would surmise cuts the normal podcast play time in half.
Pocket Casts uses an external app called Presto Sound Library to accomplish variable speed functionality, but this app appears to have been abandoned. The user forum, for example, hasn't been posted to since August, and the developer hasn't got back to my emails. Basically, the problem is that if you get a phone call when listening to something in Pocket Casts/Presto, upon completion of the call Pocket Casts force closes (although sometimes the audio just keeps on going uncontrollable). I've figured out via a helpful Play Store comment that force-closing Presto saves you from having to reboot, but needless to say this bug is extremely annoying. Problem started in Ice Cream Sandwich as I recall having it also on my CM9 Galaxy S II.
Anyone else out there have an alternative app for variable playback that works better on Jellybean? Cheers

I'm having the same problem!!
Have you found a better alternative? I especially have the problem when listening to my bluetooth headphones, lots of times the podcast just keeps playing uncontrollably. I've started rejecting calls just to quit the podcast, and then call people back, which is terrible! The whole program is quite glitchy and seems to freeze at the end of every podcast--for me at least.
I love the program interface, etc. I just wish it worked better.
I haven't been able to find anything else really. What was the tip about force quitting presto? It doesn't show up in my task manager, am I missing something?
Thanks!
I use Dice Player https://play.google.com/store/apps/details?id=com.inisoft.mediaplayer.a to play lectures at increased playback speed. Works great for that purpose. I dont think it has a podcast downloader ability though, but if you have the files on your phone, this app works great for variable playback
Anyone having any problems running aftermarket roms? I'm on Liquidsmooth and I am extremely dissapointed in the bluetooth quality. About to go back to stock or get rid of the tablet to just use my tab pro instead. IT doesn't skip or pause but it like, mutes for a second every 5 or so seconds. Its not consistent. But it happens soo much it gets me really angry. I'm on a fresh copy of LiquidSmooth. Haven't really done anything and nothing is running in the background that could be taking up all the system resources. I've even tried multiple music players even tho they all are horrible except PowerAmp which still doesn't have a tablet mode years after said feature was in the works.
You know of any fixes?
Googled Android Bluetooth Skip and seems its a very common problem among a few devices including the Note 4.... I don't have any issues with my Tab Pro, Just Tab S... This is bugging me because its main function is to play Music Via Bluetooth. Would prefer it through RCA/3.5mm but I don't have one
Had the same problem with my phone, solved it by adding the bluetooth device as a trusted device, so that when connected to bluetooth speaker the phone doesnt lock its self, done the same on my tab s and no problems streaming music using google music, as far as i can figure out its related to the kernel lowering the cpu speed when the screen locks, so you may be able to solve the prob using a kernel manager and increasing the idle speed, but personally i like the phone not locking when listening to music as i can access the player without unlocking, making it easier to put on a different album or song, hope this helps

Use to have similar issues with the stock player on another device.
Solved it with Playerpro.
Install from play then in the app open settings then go to Audio.
Select to install the dsp pack then make sure it's active.
You will see a new option 'Audio buffer' change this to large. See how you go.
Seems to me also like an audio buffering issue (I think PowerAmp has a larger one by default). You could try raising the minimum CPU frequency since this us often the cause for problems kind this.
On that note, don't forget that none TW based ROMs don't have support for the APT-X codec that provides vastly better audio quality over Bluetooth as long as your audio adapter/headphones/car audio supports it as well. Nothing to do with the issue at hand though.
Its not a buffering issue. Its an audio pause issue. Its extremely common with Note 4 and some others. I solved it by going to a TouchWiz OEM style rom. The AOSP roms seem to all do it. Adjusting buffering settings changes nothing. Its as if the bluetooth drivers aren't capable of handling the "power" of whats going on. The Music still plays during the pause.
So far TW Roms seem to be the best for Bluetooth Audio. I use it daily since the Tablet is the main front end to my car, with a Sony 610BT AppRemote Deck.
