My camera isn’t working

I’m trying to share a video or audio from my computer and the participants can’t hear it

• When you first click Share Screen, before you select which screen or application you want to share, make sure to check “Share computer sound” (and “Optimize for full-screen video clip” if you’re sharing a video), then share your screen

• The first time you share computer sound on a Mac, you may be prompted for admin credentials
