Share system audio in a Teams meeting or live event

Sharing your system audio grants you the ability stream sound from your computer to meeting participants through Teams. You can apply it to play a video or audio clip inside a presentation.


  • You won’t be able to contain your computer’s audio while sharing a PowerPoint file or Whiteboard.
  • Currently, we only support this feature on Windows devices.

Include system audio

To share your system audio, press Share Share screen button  in your meeting controls and then Include system audio. After you share, all your system audio, even notifications, will be enclosed 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 enable 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 clicking Audio off once you join the meeting, which will promptly mute your microphone and any audio playing from the teams meeting to stop echo.
  2. Click Share Share screen button  in your meeting controls and then Include system audio.


  • To prevent echo, bear in mind to keep only one device’s mic and speaker on in a room.
  • Try to minimise 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 operating many applications, you might encounter problems with audio quality, like lagging or cutting out. If this occurs, exiting other applications can help.

Low volume

If you’re using Windows, other sounds from your device (like notifications and alerts) are lowered in volume after you join a Teams meeting. Much of the time, that’s realistically your intention so you can concentrate on the meeting. But if you’re sharing system audio, the same setting that reduces the volume of other system sounds will even quieten the audio you’re seeking to share.

To repair this, find your system’s sound settings, locate your Sound Control Panel, click Communications and then Do nothing. Lastly, set the changes so others will easily hear your shared audio at its best quality.

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.
