Zoom test: check your setup before the meeting
Three checks that catch nearly every “can you hear me?” moment: microphone, camera and speakers. Then match the same devices in Zoom, Meet or Teams.

Two-minute pre-call routine
- Close apps that might hold the camera (another meeting, OBS, a browser tab).
- Run the three checks above; all three should go green.
- Headphones on if you're in a shared room; it stops echo for everyone else.
- Light in front of you, camera at eye level.
- Join a minute early and use the app's own preview to confirm it picked the right devices.
Questions
How do I test Zoom before a meeting?
Check your devices here first (it takes under a minute), then pick the same microphone, camera and speaker in Zoom: Settings > Audio and Settings > Video. Zoom also offers its own test meeting at zoom.us/test.
Does this work for Google Meet and Microsoft Teams too?
Yes. The checks test your hardware and browser permissions, which every call app depends on. The table below shows where each app keeps its device settings.
People can't hear me on Zoom but the mic test works.
Zoom is probably using a different microphone. In Zoom, click the arrow beside the Mute button and pick the microphone that passed here. Also check you are not muted in the meeting or by a headset switch.
My camera works here but not in Zoom.
Only one app can usually use a webcam at a time. Close this tab's camera (press "Turn camera off") and any other video app, then pick the camera in Zoom's video settings.
How do I stop echo on calls?
Echo usually means your speakers are feeding back into your microphone, so others hear themselves. Use headphones, or lower the speaker volume, and let the app's echo cancellation do its job.
