Regression: AudioTrack audio output has poor quality
Since one of the commits between version 1.2.4 and 1.2.5 AudioTrack audio output has been broken. Version 1.2.4 works perfectly, version 1.2.5 works bad.
You can use http://streams.videolan.org/issues/11390/Test.wav file to test quality of AudioTrack audio output.
Tested on the latest nightly git-master build using Google Nexus 5 (LG D821) device on the latest official unmodified Android 5.1.0 (LMY47I) and on the latest official CyanogenMod 12.1 nightly.
