Audio Statttering and lagging - General Questions and Answers

Hello
I have a serious problem that's gonna drive me crazy,
When I play a song on any music player app at it statter and lag every 3 sec, same issue with recorded voices or videos from youtube also local video in my device, also video or audio on the browsers, issue is happening with speaker, wired headset or wireless one.
My phone is redmi note 11, rooted with Lsposed.
the problem is not visible right after rebooting the phone but when any song/video is played after almost 10 sec it starts lagging and stattering even the volume control bar to increase or reduce the volume become laggy at same time when the played song lags, I have checked the battery optimisation and those app aren't optimized by it.
I tried everything disabling lsposed and it's modules same issue.
Unrooting the phone no changes
I removed all the app that I installed same issue and kept the default rom apps same issue
When I boot the phone in Safe mode the issue is not there and the music is played with no issue even the volume control bar doesnt lag.
Anyone has any idea or is there an app that monitor what's happenig that will help to discover the source of the probléme

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?

Having trouble with speaker???

Okay so I have been using Nvidia shield tablet for almost 5 month now.
Ive never used a custom rom so I wanted to try something new
I have used tablet without any problem except poorly slow on aosp rom
then I installed bliss rom from here and boom guess what my device is way faster and better than ever b4
but it gave me some problem which is making weird noises when I play music via power amp, Mx player pro (those two were the only ones I gave try)
It doesnt seem to happen when Im on youtube and when I listen via headphon or bluetooth device.. just only happnes when its on this devices speaker.
[email protected]://[email protected]/[email protected]__c (erase @ plz)
video 24 ~ 31 sec its the problem. on the video it just shows its just stopping, video recorder prolly didnt catch its weird sound but it has really weird sound on sounds like the speaker is being torn apart.. ? more like mechanical sound buzzing,,,
No symptoms shows on vlc but I can't use vlc to watch videos cuz of subtitle reasons..
+ vlc haa the same problem after playing video for an hour
I have the same issue, did you find a solution?
I had a similar issue on AICP rom: speakers where doing weird screeching noises in certain situations ( watching video on MXplayer, game load screens ).
It seemed to happen when the CPU reaches the low freq - they may not be enough to handle the workload.
I just used the built in KernelAuditor to set the min CPU freq to be 300.
No more screeching since then.

Music stops after a while

Hi,
I'm having a strange issue with the Mi4C and the latest stable V7.0.15.0.LXKCNCI (MIUI7).
On my way to work I listen to music and MIUI seems to be overwhelmed with this mighty task.
With default settings, Poweramp cannot even play a single Mp3 without skipping/crackling noises about every 30seconds.
While this alone is annoying enough, the music playback just stops after about 30-40 minutes. The player still displays as if it were playing, but no sound comes out..
I've tried
- allow Poweramp to Autostart and keep background processes using the MIUI settings
- setting higher priority and buffering for playback directly in Poweramp
The latter seems to resolve the skipping part, but the sudden stops are still there.
I found several threads with similar but not identical problems, the most prominent being
http://en.miui.com/thread-77248-1-1.html
Can anyone confirm this behavior?
Any workarounds?
Thanks
Jochen
I fixed it locking my music player in memory.. i just swiped down the app in multitasking (i'm on xiaomi.eu multilang rom)
yes, i can confirm on mokee, but not always. dunno why

Speaker volume randomly varies

When I'm on YouTube playing out of the phone speakers, every 5 seconds or so the sound cuts out from the earspeaker and the volume from the main speaker spikes for a second, before returning to normal.
Is there a way to disable the earspeaker from playing media? For some reason this only seems to happen with YouTube and not music apps like Spotify.

Try clearing data on or reinstalling YouTube
Did you ever fix this ? I have a g8x with the same problem some times, a reboot seems to fix it

I had this app called Videoder to download videos from fb/insta. Deleting that fixed it completely (removing permissions didn't work however).

Question Laggy video playback unless I touch the screen

Hi all,
Since the latest update on my A32, video playback is laggy unless I'm actively touching the screen. I'm using a T-Mobile A32 5G.
I've tested this with YouTube, Hulu, Netflix, and HBO Max. On my device, if I'm watching something, there will be a 1+ second audio delay. As soon as I touch the screen, though, this delay disappears and playback is smooth. So to me, it appears that the non-interactive idle clock has been set too low in the latest kernel update.
To be clear, this is not a Bluetooth audio delay, I'm using the built in phone speakers for playback.
This still happens on a fresh reboot, with no other apps running. I've tried resetting the phone and uninstalling or force closing all background apps. As long as I keep one finger on the screen, all playback is smooth.
I'm not rooted and I don't plan to be. Any workarounds for this issue? I'd be fine with a power hungry workaround as long as I'm charging.
Thanks in advance.
Is there any non-root solution for raising the non-interactive clock while charging? I think that would be enough to solve this issue.
