great insight gang, thanks. Additional question:
I am planning on using a mini to (1) utilize HDMI for video (sight and sound) and (2) USB for 2-channel audio. I think that's the originating question, but I am curious if the mini can differentiate when to send an audio signal via HDMI (for 5.1-channel movies et such) and when to send via USB (for 2-channel music)??
My concern is if you predesignate the sound-output to USB, you regulate all audio to 2-channel (including movies and TV shows).
thoughts and clarity most welcome!!
Michael
