While I was playing around with some sound files in AmadeusII today, I must have messed up my SoundSticks driver. They now sound strangely compressed; DVD sound sometimes does not output and VLC has lost all sound ability over USB.
USB Prober says that my com.apple.driver.AppleUSBAudio is version 1.9.9b10.
Any suggestions as to what might bring USB sound back to normal? Deleting com.apple.audio.DeviceSettings.plist and com.apple.soundpref.plist has not helped, neither did switching from USB to built-in sound and back.
(I don't think there's any connection, but I had a beautiful kernel crash when I woke my PB this morning: black screen and rubbish about "System Failure cpu=0 Corrupt skip list")
TIA for any hints!
(( Just found out in Audio MIDI Setup that the SoundSticks were set to 8000 Hz output, 2ch-16 bit. Setting this to 44100 Hz and 2ch-24bit makes quite a difference
