Distorted, robotic-sounding audio on Google Meet from AirPods 2 (via microphone)
I have a similar issue and found that a sudo killall coreaudiod via Terminal fixes the issue. From what I understand this resets the audio.
My issue is exclusively with a Google Meet in Safari. A Meet in Chrome doesn't have the issue. Everyone's voice that I hear is garbled. They can hear me fine. Maybe about 25% of the time if I switch audio sources and back it's fixed.
