MixBus - no master output
Newbie to Ardour and MixBus, I purchased and installed MixBus yesterday and used it all day without a problem. Today it will not pass audio to my MacBook Pro (hardware V6,2 -- running MacOSX 10.6.7) built-in output. I tried both launching JackPilot and using the aggregate audio device I made specially for MixBus. On close inspection I see that audio is making it all the way to but not including the Master Output section of the Mixer. I see meter activity in all expected areas except for the Master output meter. It's as if the Master Output is muted. Any clues for me?
Also, is there a search function for this forum? I poked around but could not find one.
