Yes always. As soon as I press on + or - after each recording starts, the logging stops. If I stop the recording and restart a new recording, it continues.

I don't think so. Where can I check this exactly to be sure? I don't have google now installed.

Ok, I checked the gain with tinymix. The value changes with each press. The level of sound also changes successfully while recording, if I play back the video. My problem is that the LED indicator stops to work correctly after one change of record level (as I said, also the logging output stops (logcat). See here:

This happens if I press on "-" for example (logcat without grep mic...):

One more comment: I installed the mod and the needed files for aMGC with the newest Aroma installer, maybe here I have a problem?

My system partition is original Lolipop 5.1 without further modifications....

Futhermore I installed CamcorderMGC-App and BusyBox Free....

No more changes.
