[Q] Problem: SGS plays music by itself. What's up?

Hi Guys,
I do have a really strange problem with my Galaxy S i9000. It randomly plays music by itself without opening any player. I can never know when it starts and even if I kill all tasks and most of the services (all I can) it won't stop. If I open the player it does not show any active playback. I can stop the playback if I slide down the upper status bar. I also can adjust the playback volume normally but it is very loud even on the lowest level.
In fact, it is always the same song (no mp3, it's a FLAC) which is located here:
/mnt/sdcard/external_sd/MP3/Paul Kalkbrenner...Berlin_Calling(FLAC)/14...
Some guys in a Moto Droid Forum already experienced the same problem with 2.1:
hXXp://androidforums.com/motorola-milestone/64497-music-playing-itself.html
I have no idea what I can do. I did not test/hack a lot and the phone is set up pretty fresh and clean.
Froyo 2.2 (JP6) flashed with Kies RegHack
Root done with ]SuperOneClick v1.5
OCLF V2+
All installed Apps are major ones and well know. So nothing special, spectacular or risky. Does anybody know what the root cause of the problem could be?
I do hope there are some ideas what I could do. Of course I could uninstall the built in player, move or delete the file but that wouldn't be a "real" solution or explain what happens. Please help! Thank you.
Best regards,
DvP

related issue
weirdly enough I had a variant of this until very recently, when it just suddenly stopped happening.
In my case, the music player would repeatedly restart itself, although it wouldn't actually be playing a track. By repeatedly I mean every time I picked the phone up I'd check running apps and find the music player there. This was on a brand new, completely un-tampered-with phone.
I went to JPM via Odin recently and rooted the phone and then the behaviour stopped.

Is there any way how I can find out which process is playing the music? I could try to make a video when the song runs again to show that no application is running at all if that helps :-/

[Q] Rom that plays video past 70min?

Hi all,
Has anyone seen a gb rom that plays or can be tweaked to play video past the 70min mark? This is a rather big thing for me, as I often take trips and like to watch movies on the plane.
I've been able to get CM6.1 and most 2.2 roms going with collin_ph's battery tweak that enables the stagefright audio. However, this doesn't seem to work with any gb rom I've tried:
CM7
aospCMod
OMGB
Deck
Evervolve
And I really like these gb roms...esp aospCMod!
Any help is greatly appreciated!

are you talking about your battery just dieing or it literally wont go past 70 minutes ive never had that issue when i was on the hero.

Are you talking about your screen freezing? Most gb roms (CM7 specifically) always had minor media issues for me. Music, videos, Pandora app etc. all freeze or skip after a while. Try using that new Wildheroc sense rom, I've had much better media performance from it versus CM7
Sent from my wildheroc using XDA Premium App

to fix the freezing just set your cpu to anything over 352 low.

This is the issue with videos over 70 mins where the video freezes and the sound keeps playing. After a while the video jumps back to about the 10-15 minute mark, but the sound is still off from where the video is.
It was discussed briefly in http://forum.xda-developers.com/showthread.php?t=864403 for a while starting at #14691, but I never saw a resolution.
This was fixed in 2.2 with the enable stagefright fix in collin_ph's battery tweak, and you could evidently do it manually by altering the stagefright line in build.prop, but when I looked at the build.prop on a couple of GB roms there was no line, and inserting a line brought no joy.
I was just wondering if anyone knew of anything, I've been searching for days and days and actually see very little on this issue. Guess not everyone watches full-length movies like me.

I actually had mine set at 352 ondemand, to help with the camera issues, but it never helped long video playback. Thanks though!

Yeah, I tried Wildheroc out for a while, but I just love the simplicity of Aosp and my LPP. I may try going back to sense though cause this is just that important to me. If I do, I may throw down on the v6 supercharger tweaks and see how that does.

[Q] Stuttering audio?

Hey guys, I searched and didn't see anything on this -- even Google did not turn up any results. I saw on the HTC One X sometimes there would be audio stutter/skips with the Beats EQ on. Sometimes when I'm playing music the audio will just glitch and stutter for no apparent reason. It is random. Has anyone else experienced this? It happened with the stock ROM as well as with ARHD7.

I am having this problem with the HTC One, streaming via bluetooth. I have raised the problem with HTC tech and waiting for a response.

I'm finding it hard to believe no one else has this problem. If it's a hardware issue I fully expect HTC to replace my unit. I will even take a recording of the stutter if necessary.

My audio will make weird noise in certain tracks and bass tones out of no where with beats on or off

I had this with my HTC One and it has been reported that it is a wifi issue. Turn it of (wifi) and it should work OK, mine does. It is a pain to keep switching wifi of and on so I found an app called A2DP volume in the play store that does it automatically.

Bumping to see if anyone else has this...

I am having this issue only when stream over BT.

Faulty sdcard possibly or your files are corrupt. Have you done an MP3 check on them?

I'm also experiencing this. Except mine skips/stutters even with beats off.
Running ARHD8.0 stock kernel w/purexaudio. I'm not sure which version of purexaudio the ARHD installed, but I went ahead and installed the most current version (v4.0) to see if it helps. So far no skipping, but I haven't tested that long yet..

There is a known issue that if you are using Adblock or a similar piece of software which modifies the hosts file that Pandora will stutter. Are you using an actual file, or are you using a buffered service that could be having an issue because of this?

It happens in the regular music player too; however I reinstalled ARHD8.1 and am not selecting adaway hosts files. I'll report back on the issue.. Thanks for the tip!

I am not using AdAway, and it happens in Play Music over the headphone jack. Haven't tested it with Bluetooth. I plan on installing TrickDroid sometime soon; I will definitely update this thread when I do and see if it still happens. Curiously, it's been happening less lately. Only once or twice a day.

So I reflashed ARHD8.1 without adblock and Pandora is no longer horribly stuttering. However it still has occasional stutters in both Pandora and Google Music. Still not sure what's causing it.

I reflashed without PureXAudio and the occasional skips/stutters still happens. Maybe once every couple minutes, really annoying considering this happened on my Note 2 also, which is why I bought the HTC One. I initially thought it might be a rogue app, but I don't have anything that could be causing it besides maybe groove IP disconnecting/reconnecting, or tasker. However I disabled both apps and the stutters still happen..

In terms of Bluetooth, the largest thing that could change in the near future would be if we get an official 4.2+ or the rumored 4.3 release, as the BT stack is recoded in that code base. This has the potential to change the game, but really considering your issue still seems to be isolated to your devices and not everyone's though, I've gotta think we're overlooking something. The further clue that you are saying this happened on your Note 2 as well also makes me wonder what else is happening.
Is this stuttering possibly during PBAP, MAP or some other profile saturating the connection with its own traffic? Is this on all BT devices that you've tested against or are we dealing with a dodgy car kit/speaker instead of a phone difficulty?

I dont use blue tooth, this is strictly wired 3.5mm connections. I don't have any uncommon apps besides tasker/secure settings/busybox/grooveip/xposed installer that were on both my note 2 and htc one. The only apps that have SU access are secure settings, xposed installer, seeder, solid explorer, betterbattery stats, and tasker.
I was almost sure that the stutter/skips were caused by purexaudio, but I guess not since I removed it.

I had this as well, does it sound like the stuff in this thread?:
http://forum.xda-developers.com/showthread.php?t=2269581
I personally had it fixed when I flashed CM 10.1 nightlies, so I'm guessing it's a software issue, more specifically maybe even androidHD

It sounds similar, sometimes the audio would cut out entirely for a third of a second, but it was not happening nearly as frequent as yours. Mine only happened once every couple minutes. Also I have since flashed bulletproof 1.9 kernel with purexaudio 4.0 and the problem seems to have gone away. However, more testing needs to be done..

I'm thinking it has something to do with CPU usage, like it running a process in the background that disrupts the audio output. But I don't know if anything can be done about that.

[Q] Audio stutter on 4.3?

Is anyone else suffering from audio stutter since the update to 4.3 and if so has anyone found a solution? I've read about lots of issues with other devices and music stutter on 4.3 but can't find anything on the Xperia Z.
I'm running the Generic UK rooted update from the Android Dev section, and I have narrowed the stutter down to when the device is sleeping.
At first I had my headphones (MDR-1RBT) on bluetooth and assumed it was that, but after connecting them with the wire the issue continued. Next I switched to Walkman player instead of the Google Music one (all music on both apps is local, on the SD card, not streamed).
The issue still continued, however, every time I wake the device the stuttering stops. I ran CPU spy to see what is going on and noticed my device has never entered deep sleep since the update (is anyone else seeing this also?)
One suggestion was that Wifi optimisation could be the issue, I turned that off, but it didn't help, and even turning wifi off doesn't seem to help, but wifi on seems to make it worse I'd say.
It's driving me insane and I use my phone/headphones to listen to music several hours a day and can't deal with the stutter, I'll have to go back to 4.2.2 unless I find a solution.

Same problem as well, except it does not stop when I wake the device - the stutter still continues no matter what. I'm using the default Walkman app as well as have tried other music apps, but same problem throughout

no issues with poweramp. try apollo or some other player (not walkman or play music) and see if that helps.

No stutter here with walkman app.
But if I run the Walkman app, the accu usage shows that Mediaserver sucks my Battery,

Same here and for @AngelBob
It's annoying and I've not been able to find a solution to it yet...

I went back to 4.2.2, so i have one question: can someone test if stuttering are not present using PowerAmp?
Thanks all

I believe it's kernel related. We had this exact issue in the past and Sony fixed with am update.

CM builds are also suffering audio 'stutters' so I think it's something we're going to have to live with until Sony push a new kernel/libs

You're right, after investigation, I can say with some certainty that the cause is the new bluetooth stack Google switched to in 4.3. I tried modifying some of the bluetooth configs but it made no difference. It'll need a fix to those libs and perhaps a kernel update as you say.
I don't know if it's been fixed in 4.4 yet, since I no longer own any nexus devices, but I wouldn't count on us getting the fix any time soon unless Sony decide to resolve it themselves.

You're right, I tested wired and it's the same problem.
In this case, I'm going to put the issue down to kernel and power save/sleep mode. I switched straight back to 4.2.2. I really like the new UI, but I can wait, hopefully 4.4 fixes it. I wouldn't count on a maintenance release from Sony before 4.4

I had this problem on 4.2.2 ROMs when I had Wi-Fi on. I think it was probably due to media server scanning for other devices over Wi-Fi network. It was going crazy when I was at uni as there were so many devices around me. Had to keep my wi-fi disabled just to listen to music.
You guys getting the same issue?

Unfortunately not, even worth wifi disabled it still happens, makes no difference.
It seems to be kernel related, perhaps something to do with cpu states or such because it only happens for me in sleep mode, it also happens when apps install so could be I/O related.

I'm starting to think sony rushed the Z 4.3 update, the T leak does not suffer this bug and it also has transparent nav bar by default!

Can we use bluetooth/a2dp libraries from other devices or versions of Android?
For example can we put Xperia Z 4.2.2 bluetooth files into the Xperia Z 4.3 firmware?
Thanks

On 4.3 Drummerjeds stock pre-rooted and deodexed rom with PXA23 I don't get any stutter when streaming. Is it only a problem with music stored on the device? (Doesn't appear to be an issue either with music from Google Play music stored on my external card). Just wonder if it could be related to my having the kernel tweaks on Power Guard Pro running in learning mode, if it's related to a problem in sleep mode?

Just want to inform you guys that I have no stutter whatsoever with walkman but I'm on the official C6602 4.3 ROM, but the screen sometimes flickers in chrome, the most annoying bug so far

[Q] Any audio mods besides ARISE/Viper that work well on Shamu w/ Nougat?

I LOVE ARISE/Viper setup - they sound fantastic! The deep buffer has to be removed to get audio streaming apps (Google Play Music, Spotify, Pandora) to process. The issue I've ran into is when you remove the deep buffer, the audio in quite a few games stutters badly. Almost like the phone is running on a low power setting. It's not the cracking/popping that happened with older versions of Viper. Some users have suggested using ICE with Config 2, but that didn't help with my setup.
So that leads me to looking for another audio mod. Any suggestions that will process audio from streaming apps and not require deep buffer removal?
Setup: Nexus 6, tried old and new versions of Viper (back to 2.33 and up to most recent 7/24), different ROMs as well (SIX, Desolation, Dirty Unicorns) and different kernels too (stock, Blackbird, Franco, ElementalX).

I was periodically trying all sound mods but my fav is ARISE. You can try this, this one is good

I'm on NOS 7.1.2 and works like a charm. I like the fact that there is no app to deal with. Just flash in recovery and enjoy. Make a backup first as there is no uninstaller for this. Or reflash your rom to get rid of it.
For me it gives good sound without all the hassle of Viper etc. Dont get me wrong I tried them and are very good but I wanted somthing simplier and to work right out of the box without having to spend to much time on setup. Hope it works for you too.
