Why won't Sound Preference Show Headphone as Input?
I've tried using GarageBand, Audacity, Quicktime, simply to record some music I have on Mini-Disc, via the headphone/audio input/output connection, and yet, it won't show up as an input option for any of them!
It shows as an output, but the only input listed is microphone. I need to make these recordings tonight, and don't know what to do. Why isn't this working the way it should?
