BTW if it is of any significance, the "mic/aux" source is USB audio from a Focusrite Solo. It was working, albeit with a horrible 2 sec+ audio lag, but while troubleshooting the lag and trying other inputs we ended up with this problem. As you can see, Windows (11) is recognizing the audio input, and OBS is receiving it, but it won't 'play' it. We've reinstalled the latest focusrite drivers.
