Title asks the main question
I currently run optical out of my 2011 base mini to a pair of powered speakers. I'd like to run USB to a headphone DAC. Will the mini allow both to be active simultaneously?
I did some testing today using an OPPO BDP-105 as a USB DAC to my mini. There is definitely no good/easy way to have both optical and USB->DAC audio simultaneously
OS X is pretty good with audio routing. You can use the built-in Audio Midi Setup utility to create a multi-output device, and you can add Soundflower for added flexibility.
Detailed instructions can be found here. Hope this helps!
Don't know how important it would be for you, but I highly doubt that both outputs would be in sync, especially if one was going through a USB DAC.
Bump.
I'm interested in buying an Atune T1. So the Mac Mini USB3 to the AT1's Type B USB will work for DAC?
(Provided I choose it in Sound preferences)
Thanks
