Details

During playback at seemingly any time this event may randomly occur.
What happens is that playback (of mp3) simply switches to strange static noises. These noises sound like radio interference from a semiconductor device, but are not.
During the glitch, volume, play/pause, seek, and all other controls function correctly. If paused and unpaused, normal playback resumes a few seconds before when the event occurs.

I once let it run and I found that
a) It repeats after a couple of minutes
b) Its repeat includes the few seconds of buffered audio

My hypothesis is that it is a buffer overrun in the playback pointer and I am hearing a core dump decoded as if it were audio data.



My player is a 2nd Generation 4GB iPod Mini.
This task depends upon
