Last night I updated my Mac Mini to 10.5.8 and all of the other updates I needed. I went to work in Garageband( I have iLife 05 atm) and at first I got a CoreAudio Error, but I fixed it no problem. Today I started it back up once I got home, started Garageband and had no errors. As I started the audio project I played one of the drum ballads on it and I got no sound at all. I checked my speakers and tried it without external speakers and used the internal speaker on the Mac, but still got no sound. If anyone knows how I can fix this minor problem(I hope it is) then please respond. Thank you.
