You join a call, but nobody can hear you—or your camera shows a black rectangle. Start by separating the problem into camera, microphone, and speaker checks.
This guide uses Windows 11 examples and general meeting-app controls. Your app’s names may differ.
The quick answer
Check the meeting’s mute and camera buttons, a physical privacy shutter, and the selected microphone, speaker, and camera. Then inspect Windows and browser permissions. Test privately before changing drivers or buying equipment.
Check physical controls and connections
A laptop camera shutter can block the picture even while the camera works. Headsets may have a separate mute switch. Inspect those controls and make sure a USB camera or headset is connected securely.
If using a dock, try a direct computer connection where practical. Bluetooth headphones may still be connected to another device. A powered accessory is not proof the meeting app is using it.
Select the device you actually want
Open the meeting app’s audio or video settings. Read the device names instead of leaving an unfamiliar choice selected. Choose your intended microphone and speak while watching the input indicator, if available.
Choose the speaker or headphones separately and use a test sound. “I cannot hear them” concerns output; “they cannot hear me” concerns input. Test the camera preview too. Seeing your picture does not prove your microphone is working.
Check Windows permissions
In Windows 11, go to Settings → Privacy & security → Camera, and repeat the check under Microphone. Check device access and the relevant app controls. Desktop applications use a separate desktop-app access setting and may not have individual switches.
Grant access for the app you intend to use. Do not assume every application needs camera or microphone access. If these settings are managed by your employer or school, ask its support team rather than trying to bypass them.
Browser meetings need another permission
For a meeting in a browser, the site also needs permission to use the camera and microphone. Review that site’s permission controls or the prompt shown when you join.
Confirm you are on the real meeting site before allowing access. If you blocked it earlier, change that site’s setting and reload or rejoin as the app directs. Close another app that may be using the camera, then test again.
Narrow down what still fails
Try the built-in Camera app or another trusted recording test. If the device works there but not in the meeting, focus on the meeting app’s selections and permissions. If it fails everywhere, reconnect it, restart, and check the manufacturer’s official support instructions.
Update through the operating system or official app source. Avoid random “driver fixer” downloads. Record the device model and exact error message if you need help.
Prepare for the next call
Run a test before an important appointment and keep an alternative ready, such as joining from your phone if the meeting service supports it. Avoid joining audio from two nearby devices at once, which can create echo.
