No sound on one MacBook Air during FaceTime call

FaceTime between two MacBook Airs (no sound on one of the MacBook airs)

I am talk to my bother-in-law using FaceTime and when we start the session I can hear him and see him, but he can not hear me.

what show I check on both MacBook Air laptops

My MacBook Air is running macOS Golden Gate 27.0.1

I am not sure what macOS my brother-in-law is running

So if you have a procedure or a check list that I can go through to check and make sure the sound configurations are correct or not on my MacBook Air and/or his MacBook Air.

Thank you for your Help

Ron

Hi there

Please try this

Check the Mute Button: Hover your mouse over the FaceTime call window to show the controls. Make sure the microphone icon is not red or crossed out.
Verify Microphone Input in FaceTime: Open FaceTime, click Video in the top menu bar, and ensure MacBook Air Microphone (or your built-in mic) is selected instead of a virtual device like Zoom or Teams.
Check System Sound Settings: Go to Apple Menu > System Settings > Sound, select the Input tab, and drag the Input volume slider up while speaking to see the level bars move.
Test the Microphone Elsewhere: Close FaceTime and test your microphone in another app, such as Voice Memos or Photo Booth, to see if the hardware picks up your voice.
Restart FaceTime or the Mac: Quit the FaceTime app and reopen it. If that fails, restart your MacBook Air completely.
