I had the same question and ran across this thread. We have a Qu-32 with usb to a Windows 10 box trying to get audio into OBS.
We are able to map our mix (mix9-10) to usb audio channels 1 and 2 . 17 and 18 seem to be dedicated to Qu-drive and do not work when we attempt.
To the gentlemen using obs using the WDM driver did you direct map the line-in Qu-32 device in windows as an aux port in OBS? When we do that we get no audio. We only get audio when we enable “listen” on the device and choose default playback device. We then have “computer audio” in OBS. Is there a better way?
