My Mac audio devices disappeared from Roon App on Monterey

Roon was working, connected to my Realtek USB2.0 Audio. I wanted to play something else, and this device disappeared. I restarted the Roon app to no avail.
I could use the connection via Airplay, but my MacStudio does not display the AirPlay code until after I have typed 4 random numbers into the prompt!

There are multipole (closed) similar threads with no real solution.
Another question, my Roon Core (running on LEAP 15.4) does not update the new releases on Qubuz. How do I get it refreshed automagically?

Please complete the template, below, described in this post. Thanks.
