Recording does not work - MAC Catalina 10.15.3

Dear all

I’m new to the software and installed it just now. I have set the value for the input resource to the build in microphone of my mac. However, the recording does not work. I tested the same with Garageband to ensure there is no issue with the built in mike an it works there.
I also tried with a BOSE headset - it works for Garageband but not for Audacity.

Is there anyone who experienced the same issue?

This is a known issue in Catalina. The next release version of Audacity will solve the problem, but until then you will need to use this workaround:
