Question [Q] Audio-Stutter since 4.3 Update (MK6 & ML2)

Hi everyone,

I experienced stuttering audio when I play back mp3 through the stock player or Poweramp. The stuttering appeared after I updated to 4.3 (MK6 and ML2).
It happens shortly after I turn off the screen and lasts for a couple of seconds when I play mp3s through the internal speaker, headphone or bluetooth.
I tried stock- and Boeffla-Kernel with almost every setting I could think of but it won't disappear.

Any Idea?
