I am trying to record a DAT into my G5 using the Optical I/O... When I go to my Sound Prefs, it allows me to pick Optical Digital-In as an option, but when I play my DAT, there is no visible (or audible) sound input. Also, after switching to Optical Digital-In in the Sound Prefs, audio applications that are supposed to use whichever setting is set in the Sound Prefs continue to show Built-In Audio.
Am I missing a setting somewhere? An extension?
