I had this same/similar issue a few nights ago when I hooked up my Bifrost 2 to my desktop PC and was playing music through Foobar. Make sure you select the appropriate output. I first selected WASAPI (event): Speakers (Schiit Bifrost 2 Unison USB) no sound but changed to WASAPI (push): Speakers (Schiit Bifrost 2 Unison USB) and then had music through the Jotunheim R and SR1a



. Usually it's something that I've done that is not correct. Patience and Persistence usually pays off. Oh and I did not see any of the Schiit Bifrost 2 options in Foobar until I did a PC restart with USB connected and the Schiit Bifrost 2 powered on.
