my 1st gen AirPods Pro work just fine on my MacBook Air M1, but sound from FaceTime only comes out of the Mac's built in speakers. I tried unpairing and repairing the AirPods, updating the Mac, restarting the Mac, and checking in control center to make sure the audio output is set to AirPods. no matter what, they just will not work in FaceTime but work on everything else. I've noticed this since Ventura 13.2. I'm currently on the latest version of macOS, 13.4. works fine on my iPhone and iPad.
