Say you want to play a video while presenting on Teams. You start the video, and a second later, someone comments. "I can't hear the audio. Can anyone else?"

Nobody can hear the video's sound. Oops. You shared video, but its audio didn't come along.

Here's how to fix this!

From the Teams Desktop app:

1. Select Share in the meeting's controls.
2. Click the Include sound toggle to turn it on.

(If using Teams on a Mac, you may be prompted to install a driver. Go ahead & run the install; you'll only need to do it once.)

From the Teams web client:

1. Select Share > Screen, window, or tab to open the screensharing selection window.
2. If you choose:
   1. "Tab", turn on the Also share tab audio toggle. This shares the audio coming from the active tab. (Audio from the rest of the computer will not share.)
   2. "Entire Screen", turn on the Also share system audio toggle. All the audio coming from the entire computer will share.
3. Select Share.
4. Select Stop sharing when you're done.
