Why can people see my shared video but not hear it in a meeting?

Seeing the picture does not necessarily mean the meeting is receiving your computer’s audio. In Zoom, the sharer needs to enable Share Sound for computer audio to be sent with the screen share. Zoom says you can select it before sharing or enable it after sharing starts. [S1]

Check the sharing controls for Share Sound and turn it on if it is available. Then ask someone in the meeting to listen to a short sample. Hearing the video locally only confirms that your computer is playing sound; it doesn’t confirm that participants are receiving it.

It can depend on the client. Zoom’s instructions specify desktop apps and the Chrome web app for this feature, and the documented steps differ by client. [S1] Check the instructions and controls for the client you’re actually using rather than assuming another device or browser has the same option.

For example, before presenting, open the sharing controls in your planned client and look for Share Sound. If it is not there, note the client and device, then check that client’s guidance. The supplied source doesn’t establish that every device, browser, meeting platform, or video player supports audio sharing.

Try a brief test with someone who can report what they hear:

1. Join using the same client and device you plan to present from.
2. Share the screen or window containing the video and confirm Share Sound is enabled.
3. Play a few seconds of audio and ask the listener whether it is clear, quiet, or silent.

If the listener reports silence, stop and restart sharing once, then check the audio option again. Record the client, device, share target, and listener’s report if the problem continues. This test helps distinguish local playback from audio reaching the meeting; the supplied Zoom source does not identify every possible cause of missing audio. [S1]

Yes. Zoom warns that joining on both a phone and computer can route audio to both and potentially cause feedback. [S1] For a simpler test, note which device is handling meeting audio and avoid having both devices play meeting audio unless your setup requires it.

Before presenting, confirm the video plays locally, enable Share Sound when sharing, and ask a listener to verify a brief sample. If the controls differ from these steps, check the guidance for your meeting client. Testing with the same devices and client you’ll use is more informative than checking only that the video plays on your computer.
