Problem with my microphone

Hello team,

I got some problems with my webcam mic.

My microphone is displayed in the settings, but I can not speak.
Strangely enough, it works while I was in the office, but at home it seems to have a barrier.

best regards
Jonaz

Need more info. is this a built in on a laptop???

Or is this a standalone web cam you move from office to home??? If so what OS’s at the two locals?

Also what programs are you using???
