mac microphone not working right
Hi, I hope someone can help, I have tried everything I could find online! My MacBook is 2017 , recently updated. The microphone stopped working in the middle of a zoom meeting. It no longer works on
zoom,
voice memo recorder
settings.
Yet It works perfectly for
Siri,
dictation
online microphone checker.
I have done all the stuff that has been recommended. Updated, restarted, pram, checked that all the relevant settings are ticked. I am at a loss now and have no idea what is wrong. It would be easier to understand if it wasn't working at all, but it does. Siri can answer anything but tells me he can hear me ok when I ask him! ZOOM is important and it is getting embarrassing. Ny help would be very much appreciated.
MacBook Air 13″, macOS 12.2
