I can't repair permissions because I'll get this:
Any ideas? I want to get shutdown/restart working.
I'll take my AppleHDA.kext from Leopard and bring it into SL. I'll let you know.
How about my wifi? I have Atheros AR5007, which works fine in Leopard. It shows up as airport but I can't turn airport on.

UPDATE2!!!: I downloaded voodoohda 0.2.2, installed it with kext helper, and my audio instantly started to work. Mute works properly too
