Any pointers on how to detect the built-in input's input volume? (as labeled in System Preferences)
I’d like my use of AVAudioEngine to set the default inputNode volume at app launch to something reasonable based on the built-in input’s input volume.
That is, keep it low if the System Preferences settings are high.
This would be even better if there’s a way to detect whether it is the built-in mic and not currently headphones or other external mic.
Detect if the self switching audio jack plugged in?
Also, any notifications to subscribe to on those System Preferences settings changing?
