Manage audio settings in Microsoft Teams meetings

If people in a meeting can't hear you, you might be muted or you might not have configured your mic correctly. Some devices have a physical mute option on the device itself, so check that your headphone boom is not in the mute position (usually upright or away from your mouth), or that your external microphone's physical mute button is not turned on.

To change your speaker, microphone, or camera settings when you’re on a call or in a meeting, select More options  > Device settings   in your meeting controls. Then, select the speaker, microphone, and camera options you want.
