Hi Bertrand, I don't have an Apple Silicon Mac to test with, so I'm not sure if this will work for you, but I just tried debugging an AudioServerPlugIn on macOS Monterey (12.2.1 (21D62)) and it seemed to work for me. Here's what I did.
1. Disabled SIP. 2. Searched for the name of my driver bundle (e.g. "My AudioServerPlugIn.driver") in Activity Monitor to find the PID of the process it's running in. The process was called "Core Audio Driver (My AudioServerPlugIn.driver)". 3. Opened Xcode and clicked Debug > Attach to process by PID or name... 4. Entered the PID, chose "debug process as root" and clicked Attach. Then I tested it by setting a breakpoint. It doesn't sound like I'm doing much different to what you've tried already, but maybe there's something subtle that's making it work for me.
