Everytime I play music... I've tried spotify and Play Music. There is a loud high frequency noise that happens for like .5-1 second frequently throughout the playback. This is through using headphones. It really interferes with the music. It's extremely obtrusive. This happened to many roms I have installed, but never really got around to asking for help.
I used to have that problem with the earlier builds of CM12 but they don't appear in the newer ones, however now it's too quiet to actually hear.
Have you gone into developer options and changed from Nuplayer to Awesome player (or vice versa)?
Same Problem here. On stock rooted ROM the problem was existent but not that often and annoying like on Temasek SM 4.7 CM 12 build.
Changed build.prop setting (can't remember the option and value)
Set screen off cores to two.
Installed Viper4Android with High Quality driver.
Changed from Nu to Awesome Player.
Nothing took effect. The issues are unpredictable and sometimes every 20secs and sometimes every 2 minutes...
I have the same problem when listing to audiobooks.
Tried changing av.offload enable to both true and false. dident work.
One thing that seems to have work is change minimum cpu frequency to something round 400 MHz.
I have the same problem with Temasek's 2.5.1 with stock kernel. Its very annoying and it comes on with screen off or screen on. Doe anyone have a fix for it?

My gTab is running VEGAn 5.1.1 w/supplement. If I play a mp4 and let the tab go to sleep, sometimes when I wake it the audio will be off (still on according to settings) or even worse there will be a repeating white noise. The only way I've found to get audio working again is to reboot. I've tried the stock player, ES video and Mplayer, same results. The tab is rock solid otherwise, no errors or fc's. Any ideas?
I have the same issue with my tablet running Vegan 5.1.1. It also happens sometimes just after you wake it up. I made sure last night that sound was working and this morning after wake from sleep I tested it right away and there was this horrible 'white noise' again (which can't be turned off even by muting and lasts for 5 seconds).
Search reveals some people having this problem, but I could not find a solution. I'd really like to know if it is a software or hardware issue so I can decide whether to send it back or not.
Would a reinstall of the rom help?
audio noise
I am running VEGAn GE 7.0.0 on two different gtabs and have experienced the same white noise issue described above. Occasionally when waking up I have experienced a blast of white noise from the speakers. Sometimes it stops on its own (after about 5 sec) other times I have to reboot.
Has anyone found a fix for this yet?
I listen to music from my N5 a lot.
Before I got my N5, I used PowerAmp. This is not possible anymore, because certain audio glitches happen every roughly 5 mins (sometimes more/less often). The audio glitches can best be described as a short sound (not longer then half a second) that is a mix of a pop and some sort of electrical noise, IN the headset. Basically, very difficult to describe but incredibly annoying nonetheless.
Anyhow, PowerAmp is not the only player that has this audio glitch. N7 Player has the exact same problem. Oddly enough, both Google Play Music and Rocket Player does not have this issue what so ever. I've only tested these four players, but as stated two of them has this issue.
Does anyone know why this happens? And even better, does anyone know of a possible fix?
What I know the problem is not:
A problem with the audio file itself. I can experience the glitch, rewind a few seconds and it's not there when I listen again. Also using Winamp on my desktop has 0 audio glitches.
A problem with the headset. Tried this on my SoundMagic E30's and Razer Tiamat 2.2, both get it.
A problem with the "OK Google" hotword detection, turning this off did nothing. (Suggestion from PowerAmp bug forums)
A problem with the kernel/ROM. I've experienced this with PA, PA+ElementalX, SlimKat and Slimkat+ElementalX. Also tried Franco and Linaro at some point. (All based on AOSP, so maybe it's a problem with that, I dunno)
I am making this thread to troubleshoot the issue of audio glitches when listening to music using CM12. If you have the same problem (or don't), please share any information or the ROM/Kernel you are using.
What is the issue? When listening to music either on a headset or bluetooth, the music occasionally makes a short skip or beeping sound. This happens for me only in Spotify, some have reported Google Play music and CM music player also has issues.
When does it happen? It typically occurs when the screen is off, but also sometimes when using the device when touching the display. Happens regardless if the music is offline or streamed.
Best fix right now:
- Install newest CM12 nightly
- Apply this bluetooth patch here [http://forum.xda-developers.com/showpost.php?p=58780279&postcount=1691]
This should fix almost all stuttering, but you may still get a few.
Other Possible fixes:
- Change Performace mode to 'Performace' in settings. (Suggested via joaopma on Reddit: http://www.reddit.com/r/oneplus/comments/2syi83/temporary_fix_for_cm12_audio_glitch/)
- Install AK Kernel (Lowered the glitches from about 10 per song to 1-2 per song)
- Franco Kernel is reported to fix the audio issues (not tested)
More info coming soon...
which rom and kernel are you running ?

Wait for the new nightly and stick with stock kernel and see if it fixes it. I see some audio fixes coming down.
I haven't personally tried it but people are saying this fixes it: http://forum.xda-developers.com/showpost.php?p=58780279&postcount=1691

It may also have something to do with wifi/data running if you are streaming music. Will test downloaded offline music soon.

franco kernel does fix it (somtimes a beep in the start of a song).
you can also try enable a minimum of 2 cores when screen is off, that fixed it for me before.

This seems to have worked! 45 min drive home and no skips in car bluetooth. Tried both streaming and local files.

I did try that with AK, thought it would work but it didn't for me.

I used boeffla kernel and switched to [zzmove native 2 cores min] in hotplug settings. it worked like a charm.
additionally, disable the mpdecision in device control (if you have such a thing in cm12, i have it on blisspop) and tick CPU Set on boot.
also lower the min freq in device control to 300mhz.
this actually fixed it for me.
i only have to switch between the hotplug settings while listening to music or not.
sucks that this fix is only for One Plus One, I have a S5 but I really wanna try this.
bluetooth skipp/stutter
I just discovered my bluetooth audio stutter on CM12.1 was caused by gasbuddy app... force stop - perfect play. open it, stutters...
dang.
it has been in and out on CM12.1 nightlies for while. finally seem to isolate it.

I just tried this after reading over at the CM forums.
Yup, using Greenify to freeze GasBuddy immediately solved my issue.
I even tested, unhibernating GasBuddy, and it brought the issue back.
(I contacted the developer, and it sounds like they have recently installed BT permissions, getting ready for something new in the app down the road, no pun intended...maybe they need to look into BT control a little deeper if they are new to it, just speculating...it could still easily be a CM issue?)
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.
Hi all, I am currently using a Redmi Note 4G Single-Sim, running the default MIUI ROM. Recently while listening to music with the screen off, I have been encountering a stuttering/popping sound which is very annoying. This only occurs when the screen is off.
I have tried searching the internet for solutions, one of which suggesting to use the Viper4Android app to increase my audio buffer. However, I cannot seem to find the option within the app to do so.
Alternatively, another potential solution I found was the increase the kernel minimum frequency. However, as I am a complete noob at this, I haven't been able to find out how to do this.
I've done some testing myself and found out this this occurs to audio files of all qualities (320kbps and 256kbps), so it is definitely not because of the quality of the audio. Also, the music does not stutter when the screen is on, which leads me to think that the CPU frequency is too low when the screen is off, hence the music stutters. Lastly, I realized that this has only started occuring after I updated my phone (to MIUI 8 Global Developer 7.1.12). Any help would be greatly appreciated, thanks!

Tweaking the kernel minimum frequency sounds about right to me.
Maybe try a different governor.

Thanks for the reply. Changing a governor profile has solved my problem. Thanks
