Since the PC is not in my reach always, it took some time to do some research, then check, then research, then check again.
What I know so far:
- the ASIO plugin works almost flawlessly (then only issue I have is, that after OBS is started and the SQ is unplugged, it looses the signal, and it does not reconnect upon USB reconnect, which should not occur at all).
- others had issues using the SQ over USB for WDM audio playback, they had to set the playback device to stereo.
- Audacity can record from the input (by default Audacity does not know ASIO so I guess itt does it over WDM/MME? not sure), so the driver does have a none ASIO mode.
For whatever reason, OBS sees only one channel from the 32 (ummm, yeah), and no audio over it.
New firmware came out for the mixer, which allows 48khz sampling over USB for the SQ. Will test it out.
