10.6.4 USB Pro Speakers (G4 Cube) don't work on Macbook Pro
System Preferences shows USB as an Output Source in Sound Preferences and I can turn the volume up and down but nothing comes out.
I created a new account, same issue. I even deleted com.apple.audio.SystemSettings.plist hoping that would fix it and nothing.
They still work as verified by my roommates machine that's running 10.6.3 :/
help?
MacBookPro5,1, Mac OS X (10.6.4)
