Frequently asked questions about microphone, webcam, speaker, headphone, noise, and echo tests.
Why is my microphone not detected?
Check browser permissions, ensure no other app is using your mic, and select the correct input device.
Why is my webcam showing a black or blank screen?
Another app may be using the camera, permissions may be blocked, or the webcam may not be connected properly.
Why can't I hear the speaker test?
Ensure your output device is selected correctly, Bluetooth devices are fully connected, and the tab is not muted.
Why is the headphone left/right test reversed?
Headphones may be worn backwards or the audio output may be inverted by the system.
Why is the noise test not updating?
Microphone access may be blocked or mic sensitivity may be too low for the environment.
Why does the echo test fail or produce feedback?
Feedback loops occur when speakers play sound back into the microphone. Try using headphones or reducing volume.
