Korg Gadget 2 problem - Zurich

How can I fix this?
“Audio Input is disabled. You cannot use audio input”

Maybe it is also you asking on another forum:

I have the same problem. It’s been a few months since I used it, last time it worked perfectly. Today I wanted to use it with my midi interface and a microphone as I always did and it was impossible. The midi interface detects me but tells me that I can’t record.
Does anyone know what happened?
