You can share system audio when you are sharing your desktop or an application in Teams meeting. And now you can also share system audio when you are sharing desktop in a Teams Live Event. You do it the same way as in a regular Teams meeting.

Your content will not be broadcasted until a producer selects the shared content and select Send Live to broadcast it.
If you want to stop sharing your system audio when presenting move your mouse to the upper part of your screen to see the sharing control. You should be able to stop sharing system audio.
If you forgot to start sharing system audio when you started to share your desktop or application you can use the same button to start sharing system audio.
