When I playback in RealBand, I keep getting a "drum solo" and the above error message. In the log it is described as:
"Windows Audio Session error: Could not select the default input device. The error number is -9985 [2021.838.0, 1/5/2022 8:10:00 PM]"

I suppose it has to do with the fact that I only play back and don't have a recording device connected.
But my experience is still limited and I don't know how to solve the problem. It's irritating because I have to restart BB every time.

Help appreciated!
