All of my experience with SLIII comes from interfacing with Macs. Works flawlessly - I simply tell my Mac what channels to push via USB, and then route that to whatever channels I want on the console. I'm trying to get the same simple setup working on Windows, but it's all of these different WDM drivers. I assumed that WDM 1/2 would correlate to USB 1/2, but I'm not getting any signal on the console when testing from that. I've tried all of the various WDM outputs and I'm getting nothing. What am I missing? The input to windows via WDM 1/2 works just fine - I have that routed from Mix 1/2 via USB 1/2 on the mixer, and it comes through flawlessly. But, the return is simply non-functional.

I'm incredibly frustrated as this should just be basic functionality here right? What the heck am I missing? I'm just trying to send sound from restream back to the console on a stereo feed so everyone in the room can hear it. Should be EZ PZ.
