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.

I don't know about "tremendous"
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?

Music"not smooth" in playback issue

Hello, I know this seems to be a silly problem, but this starts to become really disturbing. I don't know why when I play some music with my headset plugged into my phone, the songs play as usual, the quality is satisfactory, but lots of time the songs stop and continue by itself (buffer if you like) and you can obviously notice the gap between them (it is really small (about 1/1000 seconds; but you can definitely notice it and it is very disturbing when you are really in the music). I have this issue in my GT-N7100, but also in my MB860 as well, so I do not think this is a problem for a specific device. I've tried different audio drivers and different headsets (I am currently using the Beats one). If it doesn't changed anything. This problem happens most often when I am on a bus trip or in a car, but less frequent when I am at home or in a library. Does anyone has the similar problem and knows how to solve it? Thanks.

First I thought, it might be a RAM problem but for such a strong device as the GT-N7100 it shouldn't be a problem. Do you use a certain music player or does it happen with different players?
EDIT: If you are using some kind of equalizer, try turning it off and see if it helps.

Thanks for your reply, I previous use Poweramp with the MB860, and now PlayerPro for the GT-N7100. They all have the same issue. And I do not think it is a RAM problem too, since even when I use my iPod touch (with only 1 core), it plays music like charm!

I never use equalizer since it makes too much noise with some songs.

Ok, that was just a low CPU speed issue. I fixed it by setting it to at least 800MHz.

Sound Bug - Bottom speaker sound going through ear speaker/not working at all.

Occasionally the sound in the bottom speakers will stop working and some apps will play through the ear speaker instead. When this happens Google Music, Youtube and some other apps won't work at all. For example pressing play in either of those apps does nothing, as in the play button never changes to a pause button. My alarm app on the other hand plays through the ear speaker instead of not working at all. The ear speaker sound volume is very quiet and doesn't appear to be controlled by the media volume either.
The only remedy that I've been able to find for this is a phone reboot

Wanted to bump this thread -
I originally thought this issue was related to Bluetooth because I use multiple bluetooth devices, but this has happened again recently when I didn't use any Bluetooth devices.

I have the exact same issue, and it's occurrence is random. This started happening a month back. I'm guessing this is due to some software update or something, but its really annoying and the only fix is a reboot.
Anyone has any ideas, whats going on ?

It's been happening multiple times a day lately! It's gotten substantially worse over the past month. I was watching a video, sent a text and when I went to resume it wouldn't play - low and behold the bug came back.. definitely appears to be completely random.

Sent from my SAMSUNG-SM-G930A using XDA-Developers mobile app

This problem is driving me crazy

I have the exact same issue. Factory reset and update to newest firmware didn't help any idea?

Wash your phone. And wait till it dry.

I (and other person that I know) have the same issues.
No sound from bottom, and sometimes during the call no audio (I can't ear evrything and the other don't ear me).
Now I'm tring the mobile phone in safety mode.
And I've seen (for the edge version) that next android could fix the problem.
Someone have any update?
Have you tried the safety mode?

Im pretty sure its caused by Facebook messenger and Skype

From what I can tell, this seems to happen when you are playing any kind of audio, such as a video or game, and then receive a notification. You then go to the notification to respond to it and go back to your app that was playing the audio and the issue appears. It seems to be an issue, at least with me, whenever notification is received and subsequently answered.

Media Volume Mutes on Playback with Headset

Hi,
I've got a strange problem which no amount of searching and experimentation has fixed...
Whenever I start playing audio the media volume reduces to zero / mute by itself. I can then turn it back up and all is well, until the end of that song / video at which point the problem repeats. This occurs in all my media playing apps.
This only happens when using my wired headphones that have a builtin microphone. I don't get the issue on speakers, with a non-microphone headphone / external speaker, or with a bluetooth device.
I've tried the headphones on another phone (not OPO) running the same version of cm13 nightly, and the problem doesn't occur.
So I'm fairly sure that its a software bug/setting issue, but I don't know what.
I've tried making sure all other possible audio players are not started at boot and force stopped to make sure its not some weird app/clash.
Would appreciate any suggestions!
Thanks...

+1 for that issue I thought it as due to faulty buttons .......

Glad to hear its not just me! It even does it in safe mode.
I guess the only thing to try is a different ROM...

The best thread I've found that describes this problem is:
https://www.reddit.com/r/oneplus/comments/3jkilb/oneplus_one_volume_automatically_decreases_to/
Sultanxda's comments describe whats happening nicely.
So in a last and final attempt to fix this I tried some different ROMs. I tried the latest cm13 stable, sultanxda's latest and even went back to good old kitkat! But all had the same problem....
It would seem this is a hardware issue that is only getting worse. I've had instances now where the volume will mute whilst playing a song). Sometimes it mutes and then turns on Do Not Disturb!
Oh well.... time for some bluetooth headphones.

A serious bluetooth audio latency problem on OP6

Bluetooth audio has latency. We all know it. Using my Aptx-enabled bluetooth earbuds on my OP6 while watching YouTube, Plex, VLC, etc has no discernable latency. Perfect.
However, on my OP6 I have a massive issue: all games, not matter what kind they are, have around 300-500 ms+ of lag, making any game of any kind totally unplayable, from the resource-intensive PUBG mobile to any random 2D side scroller indie title. ALL games. ALL the same lag with audio only over bluetooth.
I have two nice bluetooth earphones, and various cheapie ones, and ALL of them exhibit this problem, including the aptx, bluetooth 4.0, 4.1, and 5.0 ones. This is also true on clean flashes of OOS 5.1.8, 5.1.9, 5.1.11, and both open betas for Pie. NO difference whatsoever in terms of bluetooth lag: all videos and other streaming services perfect, all games completely unplayable.
I've messed with every normal bluetooth menu and developer options bluetooth menu settings I can find.
Am I missing something here?

Sorry for your problem man, but I use oneplus's bullets wireless earbuds 99% of the time and I have zero issues.

Thanks for the sympathy. It's indeed frustrating. No one is talking about this that I can find.
So you have no real audio latency in games at all? My latency is huge and anyone would notice it, so if you say no, I believe you. What are some specific games that you play?
I've actually had my sights on the bullets. I know they use aptX, which is supposed to be great for latency...but I already have some aptX earbuds! Is there something else technology-wise going on with the bullets that would have a different result than mine?

I used to face latency but somehow it got solved after I uninstalled V4A. But what I have noticed is that volume on Bluetooth devices varies. Like it reduces suddenly and then gradually rises to the set value.

I've never installed V4A

I really don't notice any audio lag. I don't play too many games though, Minecraft, asphalt 9, and fortnite are the only games I play regularly. And I'll occasionally download a random game from time to time.
However, my phone is also rooted with magisk 17.1 and I have a few audio modifications. All modules I have that could possibly change audio are Viper4Android through xxx NoLimits 2.9.2 (along with whatever else that installs that affects audio), Android audio fix, and audio compatibility fix. Maybe one of those fixed the problem?
As for the bullets wireless, these are the most expensive earbuds I've had, which obviously makes them best, but they are really good, especially when you use them with V4A. However, I can't recommend you going out and spending $70 on more headphones with the possibility that they'll still lag for you, that's your call.
I have no idea what the problem is for you, but that seems really frustrating, I hope you figure it out or it works itself out. Best of luck to you.

i would suggest maybe clearing the bluetooth cache? Its an odd issue, but i've experienced it before as well, on youtube nonetheless. Then it somehow just went away. i dont play games on my phone, so im not sure this will work, but its worth a shot.

Even though this flash is under 24 hours old, I just tried clearing the bluetooth cache. No luck.
I also tried installing V4A and messing with some settings. No change for better or worse. All video content is synced perfectly, all audio in games lagging behind badly.

same here dude, lags only at games, with or without v4a + audio fixes for multiple v4a and sauron

Thank you! You are the first person to mention this that I've seen. Maybe we are the only two people in the world who play games on a OP6 with bluetooth audio, or do other people really not notice a near half-second delay with all sound effects with they play literally any game on the Play Store? You'd think that would come up somewhere...
So what do we do now?

Wow wow wow, hold on, cowboy

I can't help but think this is a hardware problem...but because we have no latency issues with videos at all, how does that point to a hardware issue?

Is there any news about this, because really it suck that we cannot play a game with BT, even when i chat there is latency between pictures and audio, at first i thought it was because of the bad connection or something but when i tried pubg ther was latency, but with the walking dead there was none , very strange

I'm a Youtuber bro playing heavy games fac same problem ?

Why does not a SINGLE review mention this? Why is this a tiny 2 page thread and nothing else? Are people who play some games with a BT device really so few?

I also faced this and switched to wired headphones, maybe we should raise a bug report to OnePlus, hope they can do something.

Did this mean audio lag?
i have problem with playing spotify... it sometimes like blank for 1-2 seconds then sound appear again.
And, playing youtube also same... video still playing.. but sound disappear for around 2 secs and appear again.
This when i playing thru Mi bluetooth speaker.

This happens to me as well.

I even tried to check the BT settings on the developper tools , nothing really changes after you choose a setting
