I am using TeamViewer v.15.1.3937 on MacOS Catalina. My microphone works normally on any other app except TW. I have allowed permissions for microphone to TemViewer, but in the app it is always muted and not working (see screenshots).
hi, ju st take a look to this link, maybe is the sane issue.
if not, then make sure the microphone is not used by any other app, like Siri for example.
Thank you for your answer, but both suggestions are not related. I am not able to unmute the microphone in TViewer and it is not used by any other app (Siri is disabled).
