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] Music playback keeps pausing. Who has a fix?

My Galaxy S6 keeps randomly pausing music playback while I have it connected to the aux input in my car for no apparent reason. Phone is rooted on the stock AT&T Rom and has been restored via ODIN twice without any change. It did this before root as well without change. I have disabled nuplayer in the dev settings and tried resyncing my library multiple times thinking it was due to corrupted files. This clearly is a samsung issue and seems to be apparent with older generations of the Galaxy series as well. Does anyone have a fix? I can't imagine the rest of you are actually putting up with this bug on a $600 phone. It's really driving me nuts having to keep fiddling with the damn phone while I'm driving to unpause the music, raise the volume past the warning, just to do it again a few minutes later. Tried the stock music app as well as doubletwist, no changes. Could this be caused by some motion sensing feature that needs to be disabled?
So who here has a fix? Appreciate any tips or solutions. Thanks

I know I'm not the only one. Who knows the fix and wouldn't mind sharing? Thanks

Bump for info

I have a similar issue, as my Bluetooth earphones just stops playing music. The the strange thing is that my other pair of Bluetooth earphones work fine, and I've never had any issue with other Bluetooth media connections (including those in a car). It could be specific to your car.
I'm using Google Play Music.
Have you tried it with another system?

Do you guys happen to have the music pause gesture? Had this problem with the note 3 where video seems like it was lagging really bad but it was actually pausing and unpausing because of smart stay. Turned it off and it was perfect. It's probably a screen protector messing with the sensors for the gesture.

I faced this too.
This happened when i play music directly from the Widget. However if i open the app and play music, it didnt stop.
Hope this helps.

Blame the ****ty memory management that keeps killing apps.

OP, are you saying that when it pauses, it also resets the volume warning? Or was that just additional annoyance?

^^Combination of both. When playing music on the device via aux in my car, I have the phone set to max volume, then control volume output via my car. When using the stock music app, doubletwist, etc, the music will randomly pause playback for no reason while the screen is off while the phone sits in my lap untouched. Smart stay is off, and I'm running out of ideas honestly. Been listening to Pandora recently and haven't had issues in the past four days, so it's something with music playback for the device only. Any ideas would be appreciated. Thanks

Maybe your cable is loose or has a bad connection on one end or the other? When you unplug headphones, music playback stops. Try using an app like Trigger or Tasker to make something happen on headphone unplug, such as launching a certain app or whatnot so that you'll know if the phone thinks it got unplugged.

Try clearing the cache of the music app ir use Cache Cleaner (downloadable from Playstore) to clean all cache. You can also try going to recovery mode to wipe cache.

Unfortunately I clear cache weekly, and am certain its not a connection issue. Are there additional touch or motion sensor other than the smart stay function (currently disabled) that could be triggering this?

I don't know what to tell you. Using aux is similar to plugging in via headphones and I've had no issues in that regard. I've had no problems with Bluetooth streaming either. In cases like this, it could be app interference or faulty hardware.

Is it only happening when you're using it in your car? What about with headphones or BT audio connections.
Do you have any sound effects enabled? I noticed that SoundAdapt really affected the performance of my phone, so it could be a factor.

I'm almost certain its some kind of gesture that is interfering. I don't use any of them and will gladly disable anything that could remotely cause this. I noticed the other night when my friend was driving my car, I was sitting in the passenger seat with my phone playing music through aux for at least an hour and no pausing whatsoever. I had the phone in my hand the entire time instead of near my leg sitting face up on my seat, which made me realize it must be some lockscreen gesture interfering. Any ideas?

Is the screen actually on? I don't know of any gestures that have an effect while the screen is off other than the one that makes the time display pop up, and I don't think that would cause music to pause.
There's a gesture that mutes if you put your hand over the sensors. Maybe it thinks that is getting tripped? But I don't know if that would cause the music to pause. Maybe try intentionally doing that gesture to see what effect it has?
If you think it's a gesture, just disable all of them and see if the problem clears up, then slowly reenable them to see when it breaks again.

Thanks. I will try that and let you know. I went ahead and disabled all of them. The screen is off btw when this happens.

I think it is because you are playing the music on full volume. I believe that the phone on some songs can't support the power output causing it to pause. Try instead playing it one level less than max. I noticed that this only happens with some songs specifically at max volume. This doesn't happen at a lower volume on these songs.

Galaxy s6 edge and s6 music pause or stop issue fixed
i had the same issue with my Samsung Galaxy s6 edge. music stops or pauses especially when i am using Soundcloud, pandora, Milk music player or Beatport.
but i fixed the issue .
First open the "Smart Manager" app and select battery.
Second select "details" and you should see most of the apps that uses more power.
Select "Cancel Auto stop" on the apps u want will be using especially your music app. if you don't want then to stop after sometime.
Thank you
Hope this solves ur problem

I am having this same problem on my S6 edge. Not rooted (first phone I haven't felt the need to root since the Evo).
It happens whether using connected headphones, bluetooth headphones, or in the car A2DP using the Google Music app, Pandora, or Slacker.
Was hypothesizing that notifications are causing the pauses. Would like to try the suggestion above but WHERE IS THE SMART MANAGER app?
Also, was wondering if anyone with the problem fooled around with the animation scale settings described here: http://www.digitaltrends.com/mobile/galaxy-s6-tips-and-tricks/4/ (under How to unlock Developer options)? Wondering if that is causing my/our problems.
Thanks,
Tony

Odd problem: Playback stops for no reason sporadically - HELP !

Hi folks.
Sooner or later any audio playback stops, just as if I had pushed the pause button.
It affects different apps.
I deactivated each and every special feature in settings, no matter what it is, from gestures to case type. Blutooth and NC is deactivated.
It happens with and without case, wired or not, screen on or off, flight mode or WLAN or 4G.
Sometimes it happens a few times in a few minutes or even several times in one minute. Sometimes it doesn´t happen in an hour or more.
I´m completely clueless.... This is a serious problem for me. Who can help?

Same issue here. Watch a video and sound just stops. First time happened I also tried to start poweramp and same issue.
I need to restart the phone to get everything normal.
I feel the software is not complete, there are small bugs and issues that needs solutions.
I hope an update will get it right.

Oh no...
But wait: You say: Sound stops. But video playback continues? In my case, playback in general stops, not just the sound. But I did not see that with videos since I just playback audio files.
I found out, it seems, this affects not all apps. Too bad most apps are not satisfying. (for my personal needs)
There is a app called MyNoise. It creates sound scapes with generators. There is a "CPU-Mode" option where you can select 2 different CPU modes: "High CPU" and "Normal CPU". "High CPU" was created to prevent the app from stopping to work in certain situations because of power saving features. Maybe this is a hint.

Not sure if it's related but I've started having problems in the car, when I turn to my phone's on-board music (on SD card), there is a delay of approx. 10 seconds before any music plays. It never used to be like this, I may be wrong but I'm suspecting it's since the update to EMUI version 182.

More Pixel 2 Bluetooth Woes

I know Pixel 2 bluetooth problems have been discussed here and elsewhere ad nauseam, but I honestly haven't found anyone else experiencing the problem I'm having. Or really even close. None of this was an issue with my Nexus 6P, which I just replaced.
First problem: Audio programs mute between tracks. The phone thinks it's playing them, but it isn't. Take Pandora. A few songs will play fine, then one will end, and suddenly it'll go mute when the next song starts. I'll notice no sounds playing, and I'll look down to see it think it's playing, but with no sound. If I pause and hit play again, the sounds start up until the next song, when it does the same thing. This happens with every audio program I've tried EXCEPT Google Play Music, which works fine. It also sometimes works for 4-5 songs before tanking.
Second problem: notification noises suffer the same fate. I'll have Google Play Music going (which works), and it'll just cut out for a second). That's the notification buzz, which silences the music but doesn't actually play anything. Obviously I can't use the play/pause test to see if that fixes this.
I'm using Soundpeats Q16 true wireless. I unfortunately don't have much else with which to test this. I'd blame Soundpeats, but they worked great on my 6P, and the bluetooth problems with the P2 make me think it's not on Soundpeats here.
I've messed around with the Developer options, and I THINK that setting the Playback Quality to anything steady (330kbps, 660kpbs, or 990 kbps) fixes it. The problem is that that, and the other Bluetooth developer options, all reset on me almost immediately, so that's tough to prove. I have also tried messing around with Tasker, whose sounds also wind up muted.
So one question I'd have would be: is there a way to make those developer options stick?
Second question would be: anybody else in this boat?
I have tried both re-pairing and factory resetting the headphones, several times.

Latest T-Mobile update break bluetooth?

No, I'm not using the Oreo beta.
Yesterday I had the strangest issue happen. While I was driving (Ford Sync 3), I was streaming Spotify via bluetooth and all of a sudden the sound quit coming through my car and started playing through the phone speaker. I checked, bluetooth was still connected. I could still pause/play, skip songs, etc through my car, so I have absolutely no idea why it quit playing. I skipped a few more songs and eventually it decided to start coming through my head unit again. It's happening literally every time I get in the car now.
No issues with the gfs iPhone 7+. I did notice that while all of that was happening (I went to go record the issue) that my video record button in the camera app was greyed out and wouldn't allow me to take video. After the sound resumed through my car, it would let me record again.
Any ideas?

Just wanted to bump this to figure out if anyone had any input. I noticed that after I get out of the car, if I try to adjust ringer volume, it is changing "in call volume" rather than notification volume. This ONLY happens after the bluetooth issue happens. I'm not sure what's going on here.
