[Moto G Android Development] herna:
Well seeing the error seems to be related to AwesomePlayer, AudioPolicyManager and AudioTrack, that means error can be also because frameworks/av is not updated. I am speaking about Audio of course.

Here there is a list of few fragments that logcat gives:

Seeing all this I am thinking that we have not updated frameworks/av missing few commits from CAF that is why Audio is not working properly.
