Hi - just started to use Boxee and love it (mac mini, flat screen). I have an external DAC plugged into a USB port on my mini and into my HiFi. For web shows (Hulu etc) the sound plays fine but with media stored locally it plays thorugh the Mini's built in speaker (which is pretty quiet). i tried setting it to my DAC in general settings but it didnt seem to work. Am i missing a key settings box?
