I am a happy new owner of the awesome StudioLive AR12c. I have windows audio functioning through this unit. I even have all my mixer inputs available in my DAW. I do not, however, have audio from DAW to OBS. I have tried Maschine and Reaper but not Cubase 10.5 Pro. All inputs give audio to the DAW and I can hear my VST soft synths through the AR12c, just not into OBS. I do have loopback on and "Virtual" selected, but I am new to using Loopbacks, maybe I did something incorrectly.
I have Windows 10 1909, and when Loopback is set to on. I am only able to either select Mix 1/2 or Virtual, neither of those is in the Owners Manual.
