VortexBox Appliance + SOtM > no sound via USB
I'm new to this forum, but have already learned a lot. I'm hoping someone can help me with this problem: I recently purchased a VortexBox Appliance and SOtM USB-spdif converter from Simple Green Computers. I'm having no problem playing music through my Sonos system, but want to use the SOtM to connect directly to my DAC (Bel Canto V3.5). The SOtM shows up in VortexBox Player Configuration, and VortexBox Player shows up as the player in the Squeezebox Server interface. The DAC thinks it's locked on to a signal, but I'm getting no sound. I've tried several combinations in the VortexBox Player Configuration GUI, but no luck. Does anybody have a suggestion about what I might be doing wrong?
