[AC Question]

I could make guesses, but go into Superuser and delete everything that has permission. Then start listening to music on an earphone and do something side-by-side. Superuser should pop up asking to give permission to some app. That's the app causing the problem. (If it's shell, your kernel is corrupted and you'll have to reflash the ROM.)
