I just recently got my hands on a Digi 002. I had an MBOX 2 Pro before and in addition to running and monitoring Pro Tools sessions I had always selected my MBOX as the audio output in System Preferences > Sound. My Digi 002 is recognized but it does not say "Built-in Output," I'm thinking my MBOX did but I don't remember. So now when I open, say, iTunes with the 002 as my selected sound output, I can't even get the song to play. If I switch back to internal speakers as my output it plays fine (just not through my studio monitors). When I run a PT session it works fine, but up to now no luck in using it for non-PT related sound activities, any suggestions??
