You seem to have done a ktrace by only capturing your driver extension process, which causes other information to be ignored.
"ktrace dump -p 3002"
Please capture a trace using this command and upload it to the feedback
"sudo ktrace artrace -- -c"

Thats only if the Audio Server PlugIn needs to talk to a driver extension. If you want to make a virtual audio device with the Audio Server PlugIn driver, you do NOT need a driver kit extension.
You don't need those entitlements since you don't need a driver extension for virtual audio devices.
Audio Server PlugIn is only support on macOS, not iOS. You cannot create virtual audio devices for iOS.
