So it seems like the desktop capture is stuck on using "loopback" as it's audio source. Big red error message displayed. Video is passing just fine, crystal clear.

I saw the vMix support post about trying to select other sources, even silence to clear the message but no luck. Selecting silence, closing the window...it still stays on "loopback".

I would love to be able to capture the system audio, if anyone has any suggestions? Thanks.
