My microphone stops working, when I upgraded to / installed CM12.1 on my phone.

It is still working, when my phone still doesn't have CyanogenMod installed.

However, some apps, such as Cortana and calls (the stock calling app), can still detect / hear my voice; but not on Google's Voice Search, Sound Recorder, and such Microphone Apps on the Play Store.

Maybe, a library (lib*.so), permission not allowed (android.permission. ...), or somethin', is missing on my device, that is preventing the microphone to work.

Phone:   Samsung Galaxy Core Prime

Model:   SM-G360HU

Recovery:   TWRP

ROM:   CM12.1

     - Link for the ROM can be found above ...

Android Version:   5.1 Lollipop

Please HELP!


I've seen an app (I installed it), and it requires root access. After looking at the log of the root access of that app, it showing a library / lib named libaudio_recorder_sf.so.
Does this lib have to do with the microphone, or any recorder (e.g. Sound Recorder app) ?

  • I can't. I don't have enough privileges to do such things ... Dec 29 '16 at 11:17
  • Just post more in other subforums such as General and Q&A. XDA is a very useful place, you'll find yourself coming back to it more later, so do take some time to do some quality posts and earn the privilege.

This bug is fixed on CM13. The microphone is now working, when I upgraded to CM13.
