My BB Curve randomly started having sound problems recently, and after doing some research, I found other users were experiencing the same problems after downloading the most recent FB version. The device basically stops playing sound - it won't ring, audio notifications do not work, media files don't play, and there is no sound in games. Doing a battery pull fixes the problem for a while, but then it recurs.
Anyone else having the same issue, and if it is a FB update problem, is there a way to go back to the old version of FB?
