Microsoft Teams supports both audio and video calls. When you initiate a call, the app, like other messaging apps, will automatically use the default mic and speakers, or the default communication device for the call. If you can hear other people in a call, but they cannot hear you, it’s possible the Microsoft Teams is unable to detect the mic.
