Need help, At some point the surge protector that my Mac Mini is plugged into tripped. Now, Audirvana plays but there isn't any sound. I checked my equipment with the CD player and the amp is working. I've checked the audio settings for both the Mac and Audirvana and everything is set correctly. Any ideas as to how to fix? I really don't know where to start as this has never happened before. I'm using USB to my DAC. Thanks!
