Audio Crackling/Audio stutter when screen off after 3.1 Update

All,
I noticed a couple possible defects after upgrading to 3.1 manually.
1. When playing audio from certain applications (XMP for Android for instance) The Audio cuts out shortly after the screen turns off, and then halts for a period of time before coming back shortly, then cuts out again.
2. Once you turn the screen back on, there is a distinct crackling in the audio.
Workaround:
1. Turn screen back on (get the crackling)
2. Unplug the 3.5mm audio jack
3. Play music from the speakers
4. Plug back in the 3.5mm audio jack
Anyone else seeing these issues with other audio applications?

Yep, I had the crackling and long pauses start happening today after the FOTA update.
Seems to happen (more often?) when applications interrupt an audio stream. For instance, listening to music and get an IM or email.

Yeah I had issues with this as well afer updating to 3.1...I saw in another thread that doing a "hard reboot" will fix the issue and has seemed to work for me so far. Hold the power button down for 10-15 sec until the unit reboots.

same problem
I have the same problem as well. The audio stops functioning properly when the screen times out or when I lock the device with the power button. The weird thing is that this behaviour is not consistent for all apps.
For example, "Music" stops only at the end of the song. From the "3.1 ROM issues" thread, other users are experiencing this as well. In contrast, in the apps "Listen" and "Audible", almost as soon as the screen goes off or I lock it, the audio stops, starting after some 30 seconds, halting again after 10 seconds. It repeats this cycle a few times and then stops completely. If I lit the screen by hitting the power button, the audio resumes with crackling noises as mentioned in the original posts.
Also, hard reset didn't work. I am tempted to do a factory reset except that I don't really know what's going on and I don't know if that'd fix it!
UPDATE: I found the following workaround solutions:
1- Winamp works flawlessly for songs, not a peep or hitch!
2- BeyondPod is working fairly well for podcasts. (It has paused once after 11 minutes so far.)

I did the fota update.
and I've the the crackling. Sucky.

me too. Hope they get an update out to fix this asap. Extremely annoying bug.

Would like to add I am also experiencing this issue although mine didn't start till a couple days after the update to 3.1. A hard reset works for a little while but the issue eventually presents itself again. Might be due to a caching issue with the music player?

Anyone try another music player?

I discovered the crackling noise problem last night.
At first I thought the FLAC songs were recorded from a dirty vinyl record.
I also discovered the problem where the Music app does not continue to the next song when listening with the screen turned off. How stupid is that.
These are two big problems that ASUS needs to address ASAP.
I am already annoyed by the pop sound when turning the Transformer on and whenever any sound to the speaker (Headphones are fine) is played after a long pause.
They must have used a really cheap sound chip in the Transformer.

Yes I can confirm the same problems with google listen. Have tried the hard reset but it doesn't really help very much. Things worked fine after the restart, but as soon as the screen turned off, then the audio paused, and began to crackle, then more pauses. It is almost as if some part of the system is in some sort of low power mode and is not able to feed the data at the required data rate...

I believe this could be exactly the problem. I have not yet gotten my TF, but looking forward to one greatly. However, I get exactly this problem on my Galaxy Tab 7" WHEN using setCPU to add a profile that scales the CPU down when screen is off. It sounds to me as if ASUS has added some sort of governer/scaling that does this. I could be wrong of course This is just based on reading, and personal experience

Yes. I get a lot of weird little problems with the Tab 7'' when setCPU scales clock speed down too far, including random reboots. I guess that's the sacrifice Asus made to give the TF such a tremendous battery life.

More like pretty good...

i can confirm that i have this issue using google music app. I previously purchased PowerAMP (arguably the best android music app) and no problems whatsoever when the screen goes off.
I do like the google music app as it seems like a truly lightweight player but its still in beta stage and needs a bit of work.

I just discovered something. The problem does not occur for my Transformer when the unit is plugged in!
So it must be power management problem, the question is how to fix it?

Hey guys, loving the xda forums btw, much love. I have a acer iconia a500 16gb, and same problem here:
Using Acer_a500_4.010.13_com_gen2
The default Music player is buggy and crashed fairly often, the audio stopping when screen turns off and stopping intermittently is also present on iconia with the default music player and the others as well.
The audio crackling is also present under same conditions.
To add insult to injury, sometimes when i connect a headphones the speakers dont turn off. And if i play with he "dolby mobile" settings, the sound on my headphones get really tinny untill i unplug the headphones and plug them back in, or i reboot the sys in some cases.

I just thought I should add to this thread that I have the same problems on my Acer Iconia A500. It consistently only finishes the song after I turn the screen off then it waits MINUTES to start the next song. I only occasionally have problems with the crackle sound. I had the crackling a lot when I first got it but it doesn't seem to happen as often any more. It doesn't seem to happen when I use doubleTwist but I really wish that the STOCK APPLICATION (which I like the best) would work...
Is there ANY way to fix this stuff? I mean even downgrading to like 3.0 or something. I like to use my tablet to play on my stereo system and I don't enjoy having to effing go back every time I want to play the next song. I also don't want to leave the screen on all the time and murder the battery.

I have the same thing happening on my A500 (running the ASUS PRIME ROM, though). When the screen turns off, anything audio related gets really skippy.

apparently there's some sort of setting build in for the cpu to underclock to the point of not being able to continue running the music application when the screen turns off. (that's me guessing it could be wrong) It always happens with stock music app though it didnt happen when in 3.0.
I installed winamp and doubletwist and both played nonstop.
Also i noticed that if you had music in your external sd and you open music app (also happened with winamp) and remove the sd the applications wont work anymore (thy always fc)unless you install the sd back (that is if you had your music library in the sd even if you also have it internally)
I tried moving the music to the internal storage but the error persist. the only way to get rid of it is formatting the tablet and passing the music to the tablet before running the apps. However if you install the sd and you happen to have music and music app open, youre screw again.
thats the error ive been having and im stuck with a 16gb sd in the tablet to hear music, (which i find it sucking cause my tablet is 32gb)
any suggestions?

[Q] Strange problem with Doubletwist when exiting Car Mode

Anyone else experiencing this? I have all sorts of weird issues with Car Mode, but this one takes the cake.
Whenever the Infuse exits Car Mode (whether I have launched Doubletwist in the recent past or not doesn't seem to matter), my Infuse will start playing music over the speaker from Doubletwist.
Launching Doubletwist and pausing play doesn't work, the music continues to play until I go into task manager and kill Doubletwist from there.
All I've got to say is WTF?

I have same problem when i use my Logitech speakers through me headphone jack or when I disconnect my Bluetooth. And mine keeps playing the same freaking song. Haven't figured it out myself either.

OK, that might narrow it down to disconnecting from bluetooth, since that's part of the exit from car mode. I had some unrelated issues with Navigation and did a factory reset yesterday and I'm reinstalling doubletwist. I got rid of AZW launcher as a result of this and haven't reinstalled it. I'll see if this problem continues.

Yep
Still happening with doubletwist even after the factory reset. This has to be a doubletwist bug.

I have had an issue with bluetooth doing this at disconnect. It has primarily been an android issue....not specific to any rom or phone.
Scenario 1. music playing, car gets turned off ie bt device off, music continues to play.
Scenario 2. music playing, car gets turned off ie bt device off, music pauses but resumes randomly
There was once some info in the Evo forums about this but It will take some digging for me to find it. The only solution I can think of now it to completely end (or kill on apps like doubletwist and mixzing) the music app prior to disconnect.
I will see if I can find the googl issue and the info I recall seeing in the evo forum.

I really don't think it's the same thing, actually. What you are describing seems to be a missed event (BT disconnect) that should stop an already running process (music player, doubletwist, etc).
What's happening to me is that doubletwist isn't even running in the first place and it starts playing music on BT disconnect. When you launch doubletwist to stop the music, it shows that it is NOT playing anything, while the task manager shows that it is and the music only stops when the process is killed.
I checked on doubletwist's forums and this issue has been raised and has 12 votes, beginning back in 2010, and they've chosen to not fix it.
I uninstalled doubletwist today and the problem has not reoccurred with a different app, so I think that pretty much points the finger at the app, rather than Android.

that is really odd....
I have issues with a few of my music apps that are very similar. (can't stand doubletwist so that isn't one)
many of them have no dedicated stop/end function, so even if i back out...they still linger in the background unless forcestop
THEN...when the disconnect event takes place they start playing
in your case it sounds like you verified doubletwist is not in task list running, bt disconnects/exit car mode and it starts itself?

I haven't gone so far as to check the task list before disconnect, but doubletwist had not been launched by me. I suppose it's possible it was lurking in the background if Android was running it without my knowledge, but that seems unlikely as often as this happens.
I'm chalking this up to a badly coded app and moving on.

Gotcha....yeah i ditched doubleteist for that reason...there were several system events that troggered it to open on its own...mainly plugging the phone in to a charger...the phone would go into mass storage mode every time.
U made the right decision lol

[Q] Google Music

1. Sometimes while playing music that is even cache'd to the phone it will stop after every song and I have to turn the screen on for it to advance, is that normal?
2. Is there anyway of getting lock screen controls for it?
Thanks in advance

No, it's not. Do you have underclocking profiles for when the screen is off? If so, having it set too low interferes with playing music; bump it up a little. If not, try clearing the application data (settings > manage applications > [find the app] > clear data).
As far as I know, the only way to get lock screen controls is if you use a third party lockscreen (Widgetlocker; others may work too, idk) and install Phantom Music Control.

Yea I found out it was juice defender turning my data off with screen off.

Crap still does not go to next track with screen off even on wifi or with data on

What player are you using? Some don't stay on. Try DoubleTwist.

Just the Google Music app, poweramp works fine. But I'd rather stream than load my sd card

Bump, does anyone else use Google Music? It keeps sometimes auto advancing the music and others it won't play the next song in the album unless I turn the screen on after the previous track ends. This is with Data always on or not so it's not that. I wish PowerAmp could not just see the Pinned for offline but also read the meta-data

Yes sometime it will play 20 seconds then jump to next song..

I'm having the same problem with Google Music - music stops playing after each song and resumes when I press the power button. I had this problem unrooted and rooted. I don't know if it only happens with Google Music because that's the only music app I use. Might switch over to the stock music app for a while and see if that's any better.

It's just the Google Music app, poweramp works fine or other apps.

I've been having this problem for months now, and it seems there's no interest in fixing it. It's not just your phone, either--I'm on a T-mo version of this phone and it happens on any rom, rooted or not, and I despise the built-in music app.

I'm glad I'm not the only one and going crazy haha, hopefully google will get the Google Music app updated quickly or allow 3rd party apps to access the streams

Google Play Music Skips

I'll start with this:
I'm on build 20 of klin1344's PACman rom
Newest version of Play Music
AC!D sound mod installed
-if I recall correctly my issue existed before I installed acid.
What I've been experiencing is skipping while playing music through be play music app. Not skipping as though it's struggling to buffer, but whenever I tap the screen, within as well as outside of the app. The issue isn't new to today's update, as it's been a problem I've always dealt with. It also doesn't have anything to do with streaming music vs playing music stored on the device, skips while tapping occur regardless.
I've searched around to no avail, so I do hope one of you can be of assistance.
Thanks

I have had this issue since I got my S3 a few weeks ago too. When I unlock my phone, type in password, or otherwise click the screen, the music skips.
This even happens when I am using Spotify to play music.
EDIT: BTW I am on AOKP ROM.

I failed to mention that poweramp runs smooth as a baby's bottom. Not the case with play music.

I have the same problem like it will return to the lock screen and then the Google music widget and the camera widget like combined and start flickering. this is when playing a song stored on the device as well as the new Google music access they came out with. Mine just pauses forever though and its annoying. I also have power amp and it works beautifully. this happens whether I'm on WiFi or cell data. Good thing this is a free 30 day trial!

I actually did end up figuring out what was wrong. A simple disabling of the system touch sounds and you're good to go. It was trying to compensate for the sound at the same time as playing the music, like when you get a text message it lowers the volume, plays the notification sound, and resumes at normal volume.
Jwattt I don't know why that happens, but it also happens to me. Weird.

I'm currently running liquidsmooth 2.4 on 4.2.2 android and there is no system touch sounds option. I believe this is only for touchwiz roms? I think my problem is something to do with how the widget is handled on the lockscreen. I know it's not just this rom too because I switched from MROM and before that deviant xone and since they are all pretty much based of Cyanogenmod I think it's some kind of mis match somewhere.

Audio stuttering

Hi all, just wondered if anyone else had this issue. While playing music through google play music everything works fine, even with the screen off, however occasionally when I wake the device back up I might get a slight pause or stutter in the music playback. This can also happen if I'm switching between intensive apps while music is playing in the background. I've performed a factory reset, and it doesn't make a difference if using headphones or not.

I'll pay attention to this in way to check if this happens on my phone too, i have the same firmware running except that I'm on B372 (latest build for BLN-L21C432).
Anyway, begin to warn Huawei through their contact form on their site. The first they're aware about this, the first they can work on it and find a fix (if it's possible).

I've noticed the same problem last week. Music stops playing pretty much every second time the screen gets turned off.
Same problem with Spotify and Soundcloud apps, however weirdly enough the default Music app works without any problems.
Any suggestions?
