Include computer sound
To share sound from your computer, select Share content in your meeting controls and then Include computer sound—it's the switch on the top left of your sharing options.
When you share, all audio from your computer, including notifications, will be included in the meeting.
Note: There is a specific order of operations when sharing on Teams. RemoteSpark must be open prior to initializing the screen share. If it is opened after then Teams doesn't recognize the audio. This applies to any application opened after the share.
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.
Microsoft Teams is a third-party application. Any questions or concerns about its use should be directed to Microsoft. More information can be found here.
Do not use headphones. There is a known issue with Microsoft Teams that relates to wearing headphones whilst sharing system audio with applications that require audio input and output.
