My microphone didn't work in Classroom

My opponent and I used Classroom to analyze our game. I could hear him, but he couldn't hear me, even though I thought I unmuted it. How should I have unmuted Classroom? If I did it right, then I figure there is something wrong with my microphone, which is built in with my camera.

I am using a desktop computer with a separate camera (five or six years old) that has a microphone built in. I have used it before without any problems, including four or five weeks ago.

I just tried the echo test on Skype, and my microphone worked. Either it wasn't working yesterday or I did something wrong. But it will be hard for me to figure it out because if we were rated for our knowledge of technology the way we are rated for chess, my rating would be below 500.
