.....have you taken a look in System Prefs > Security & Privacy > Privacy > Accessibility to see if Amadeus wants it?
And if not, I wonder if your unilaterally granting it would help?
That works. The default for Amadeus is to request Microphone Access but adding them to Full Disk Access allows recording without turning off the Firewall.
The input is still fixed (i.e. no fader control) but that’s fine….levels all seem to be in the -5 to -2.8 range, even on “loud†recordings. Better to be turning up a clean sound than turning down a distorted one.
