I updated to 7.7 as well as 2.0 for my touch. I thought everything was fine until this AM when I tried to play some music on iTunes. It showed the second counter going like it's playing music, but no sound. I checked to make sure no headphones were plugged it, it wasn't on mute, and all other sounds would work. Movies in iTunes will work, it's just he music that won't. I am so confused. Any suggestions? Thanks a ton!
