Running on a MacBook Pro Core2Duo 2.2 with OSX 10.6.8 Haven't had sound for about a month and a half. I've searched and searched on the forums for an answer to my solution. The red light is not on in my headphone jack so it's not a digital audio output issue and I can still hear the startup chime. Here's a list of my problems: Sound doesn't work iTunes won't open because of error 200 Computer hangs on shut down Here's what I've tried: SMC and PRAM reset Rebooting in safe boot and doing some suggested things in Terminal Repaired permissions, and other maintenance After running a virus scan (I know, I know) I found this in some of the logs: Would a reinstall of Snow Leopard fix my problem? Perhaps my audio "driver" is corrupted?
