Audio Output issues
In the Audio Video settings, I cannot choose "Firewire" as an output option because it is greyed out. But "Default," "Built-In Output," "Built-In Line" and "Digital" don't work either. No sound. And the computer's not muted or anything like that...
What setting should I use to get the audio to play through my computer's speakers?
MacPro, Mac OS X (10.4.8)
