The reason for this is most likely because you did not grant microphone permission.

I'm sure granted microphone permiss.
You can reproduce it:

Create a virtual audio device by blackhole.
Keep system audio input device is Mac's microphone.
Use blackhole created virtual input device to record in code.
Flutter run.
Get this issue.
