I am using iTunes with a Tascam US-122L audio interface. It worked perfectly fine until yesterday evening, and now iTunes absolutely refuses to play any music when the Tascam is connected. I click a song title and the diamond slider does not move, the song stays at 0:00, and the "play" button doesn't change to the "pause" button. It seemed to have started doing this after I exported a song into iTunes from Audio Hijack, which I downloaded to capture some audio from Logic Pro. I've tried everything, from restarting my computer, to reinstalling the Tascam drivers to reinstalling iTunes. iTunes works just fine except for the "playing songs" part, which is it's major selling point. It works perfectly fine when the Tascam isn't connected. I've heard of a lot of people with similar problems but none of the solutions I've seen have worked. Anyone got any ideas?
