Sharing your system audio lets you stream your computer audio to meeting participants through Teams. You can use it to play a video or audio clip as part of a presentation. This feature is currently only supported for Windows devices.
To share your system audio, select Share in your meeting controls and then Include system audio. When you share, all your system audio, including notifications, will be included in the meeting.
Note: Teams and your computer need to be set to the same speaker. Adjust your computer’s audio output in your system settings and your Teams audio output in your device settings in Teams.
