Frequently Asked Questions

Find Quick Answers

Why can't I see my webcam feed?

Ensure you've granted camera permissions when prompted. Check if another application is using your camera, and verify your camera is properly connected and not disabled in system settings.

Why is the microphone not detecting sound?

Make sure you've allowed microphone access. Check your system's audio input settings to ensure the correct microphone is selected and not muted. Try speaking louder or closer to the microphone.
