Just downloaded iTunes 10.1.1(4), and something's gone horribly, horribly wrong: playback of an ordinary audio CD (I have tried several different discs, all the same result) gives very distorted sound. I tried unchecking various 'sound control' aspects of iTunes, like the EQ and Normaliser, nothing. Still terrible distortion. I also tried playing the CD's through VLC - same result. So somewhere, something that was installed with the update has screwed things up. MP3's I had already play fine, other audio plays fine, just CD's (as yet). I'm running Leopard 10.5.8, iMac 2.4GHz Intel Core 2 Duo, 2GB RAM. Using an external Samsung DVD-RW ('Super'drive packed up). PLEASE HELP!
