Being able to hear a video on your own computer does not prove its sound reaches the meeting. Your microphone and the presentation’s media audio are separate paths. Test the audience result before an important demonstration.

Prepare the content in its own browser tab and close unrelated material in that tab. Use a harmless short clip for rehearsal. Decide whether the audience needs only the clip, a particular application window or the whole desktop; share the smallest area that meets the task.

Choose the intended sound path

In an active Google Meet meeting, use Present now and choose the tab containing the video. Check the tab-audio sharing control before confirming Share. Google documents tab audio and also describes system-audio controls for supported window or whole-screen sharing; available choices can vary with the environment.

Avoid presenting the meeting tab itself, which can create a repeated mirror view. If the video moves to another tab, inspect which tab is currently being shared rather than assuming the audience follows every browser change.

Do not turn up the laptop speakers and expect the microphone to reproduce the clip cleanly. That adds room noise and can make speech harder to understand. Use the supported presentation-audio route instead.

Check picture and sound separately

Ask an authorised test participant on another connection to confirm three things: the expected picture appears, the clip audio is audible, and your spoken explanation remains understandable. Check their report rather than your own local playback.

If the picture works but the clip is silent, revisit the selected share source and audio toggle. If speech is missing too, investigate the microphone or joining mode as a separate issue. Host or administrator controls may also limit presentation.

Stop presenting after the test and confirm that the audience no longer sees the content. Then repeat the same known working choices for the actual meeting. A short recorded checklist of tab, audio option and audience result is more useful than changing every sound setting at once.
