Powerbook G4, dual-booting 867.
In 9.2.2, the Sound control panel's audio-in level slider is greyed out.
All proper boxes are checked. (play-through, check level, etc.)
I can't adjust the level...it is fixed about halfway up.
It works fine on my Wallstreet. I even copied all relevant extensions and panels over to the G$ and rebooted....no dice.
What could be wrong?
