After reading up on the Schiit Wyrd, it just may do the trick; however:
What USB cable do you have connected? I had a similar issue with my MacBook Pro connected to a Focusrite Scarlett 2i2 audio interface; (essentially a DAC, albeit Pro Audio). Disconnecting / reconnecting the USB cable would re-establish connectivity; but I don't have to restart. Connectivity issues were reduced when I obtained a better quality USB cable; but it did not eliminate the issue completely.
I do have to state, though, that connection of my MacBook Pro via USB to my Oppo BDP-105 has no connectivity issues whatsoever. Of course, its an Audiophile (Oppo) vss Pro Audio (Scarlett) comparison.
Oh, and just a thought: have you checked your Audio MIDI Setup? Maybe the Clock Source?
