[Q] How to fix microphone bug in 12.1 ROMS

Hi all. I port some roms for my device, mt6582 , but I have found some bugs that I could not solve. in all pure lollipop 5.1.1 roms when i ported they have the same bugs. For example the microphone not work in some apps, example facebook messenger, audio record(all), google search, screen record(video not record because audio not is available). But fox example in whatsapp work whit any bug. but in other applications have the same message. "Could not access the microphone" or "Could not access the microphone, The microphone can be in use" .

Any solution? Thanks
Sorry for my bad english.
