Share system audio in a Teams meeting or live event

Share system audio in a Teams meeting or live event

Sharing your system audio lets you stream sound from your computer to meeting participants through Teams. You can use it to play a video or audio clip as part of a presentation.


  • You won't be able to include your computer's audio while sharing a PowerPoint file or Whiteboard.

  • For now, we only support this feature on Windows devices.

Include system audio

To share your system audio, select Share Share screen button  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.

Include system audio in a room with a Teams device

Teams devices allow you to share content using cables connected to the room console. Unfortunately, we do not yet support sharing system audio this way.

If you want to share system audio when you’re in a meeting room with a Teams device in it:

  1. Join the meeting from your personal device by selecting Audio off when you join the meeting, which will automatically mute not only your microphone but also any audio playing from the teams meeting to prevent echo.

  2. Select Share Share screen button  in your meeting controls and then Include system audio.


  • To avoid echo, remember to keep only one device’s mic and speaker on in a room.

  • Try to minimize the number of apps you run while you’re sharing your system audio. If your computer is running too many apps, your audio could suffer.

Troubleshooting system audio

Poor audio quality

If your computer is running a lot of applications, you may experience issues with audio quality, like lagging or cutting out. If this happens, closing other applications can help.

Low volume

If you’re using Windows, other sounds from your device (like notifications and alerts) are reduced in volume when you join a Teams meeting. Most of the time, that’s probably what you want so you can focus on the meeting. But if you’re sharing system audio, the same setting that quiets other system sounds will also quiet the audio you’re trying to share.

To fix this, go to your system's sound settings, find your Sound Control Panel, select Communications and then Do nothing. Finally, apply the changes so others will be able to hear your shared audio loud and clear.

The Communications tab of the Sound Control Panel has four ways for Windows to handle sounds when you’re using your PC for calls or meetings. "Do nothing" is selected.
