Why does my iPod touch randomly stop playing music?
I have had a 64GB iPod touch 5th generation since February. I have done all updates (as of August 3rd), it currently has iOS 6.1.3. Since about April, it has randomly stopped playing music either when a song ends or as a new one tries to start. Sometimes it stutters at the beginning of the song, I'll hear the very first sound in a song two or three times, then it will stop. Sometimes the screen freezes for up to 30 seconds after the music stops. I've tried going back to the same song and starting it again, which sometimes works and sometimes doesn't; it sometimes either "stutters" on that first sound and goes back to the playlist screen or just freezes at 0:00 then goes back to the playlist screen. I've tried restarting it again with a different song, which does the same thing. It is not isolated to just one song, it happens with just about any song, including songs I never had a problem with before April or on my previous iPod.
Additionally, my girlfriend has the same music files on her 32GB iPod touch 5th gen and has never experienced this problem. The only difference is that she has never done any updates of her ipod and I've done every update.
So far I've tried:
1) Resetting the iPod.
2) Removing all of my music from the iPod and resyncing it.
3) Removing all of my music from the iPod and resyncing it one playlist at a time.
4) Restoring the iPod from a backup.
5) Restoring the iPod as a new iPod.
6) Visiting the genius bar at the apple store, but I cannot reproduce the problem whenever I want, it seems completely random.
This would normally be a minor inconvenience, but I work in a biochemistry lab that requires me to wear gloves and work with infectious bacteria, so if the song stops while I'm working, I sit in silence for extended periods of time and that just makes me sad 😟
Any pointers would be greatly appreciated!
