For the last week, I’ve been struggling with audio skipping and battery drain while listening to music on my Galaxy Note 2 (Carbon custom ROM). I observed that the “mediaserver” process was running for an inordinate period of time whenever I played music from PowerAMP.
Turning to Google, there were several proposed methods to resolve this known issue – clearing cache/Dalvik, clean wiping the system, etc. What worked for me was deleting all my “.m4a” files (from iTunes Match) and sticking to the “.mp3” format for audio. Furthermore, I removed all equalizer adjustments (Equ, Tone, and Limit on PowerAMP).
No issues since then. Hopefully this helps someone! 🙂
