Re: Recognize Music not working .... "No result We were unable to find anything." ...
"Microphone unavailable. Connect a microphone or check system preferences."
(1) You could check Apple Menu > System Settings > Sound > Check the input / output Volume and Balance
The settings / sliders would likely need to be set somewhere need the middle.
(2) Wondering what other apps may be open, and using the microphone ... eg: Voice memos / Game apps etc.
ie: You could check whether quitting those apps while playing music can help.
(3) If you haven't seen it already: Wondering wherher adding "Recognize Music" to Control Centre can help:
