Skips, hiccups, stutters

Audio skipping is a complex issue, it can be generated by many factors:

- sd card issues (try to play same file in stock player, if it happens there as well - that's it). Can happen also if many songs/images/movies recently uploaded to the phone (stock system scanner one some devices is slow and takes a lot of SD card bandwidth)

- Bluetooth issues. This usually affects any player on the device. Try to Unpair, then Pair BT device again

- tweaked ROM/rooted phone with tweaked CPU governor/frequency. It could be not enough CPU for Poweramp audio processing

- ROM issue (some HTC Sense 4.0+Beats ROMs produces skips/slow downs audio when more than 2 sounds played, e.g. Poweramp and touch sound). Try to disable beats for Poweramp

- additional 3rd party audio effects. Try to temporarily disable additional audio effects and check if it helps

- some cpu hungry apps (free app like OSMonitor can show total and per process cpu consumption and find offending app/service)

- some broken formats (if skipping happens for the same songs, always, and doesn't happen for others)

Poweramp can be tweaked to mitigate some of the above mentioned factors via Settings => Audio => Advanced Tweaks:
- Audio Thread Priority (set higher)
- Audio Buffer Size (set higher, but this can add lags between tracks in Poweramp as buffer is larger, thus, filled slower)
