Guides
- Microphone not working on Windows 11Most microphone problems on Windows 11 come from a setting, not a broken mic. Work through these checks in order and test after each one; the first ones solve most cases.
- Webcam not working on Windows 11A black screen, a camera that is not found or an app that says the camera is in use usually has a simple cause. Go through these checks in order and test after each one.
- Allow camera and microphone in your browserA website can use your camera or microphone only after you allow it, and only while the page is open. If you clicked Block once, the browser remembers it and stops asking. Here is how to allow it again.
- Mic not working in Meet, Teams, Zoom or DiscordWhen people can't hear you on a call, the microphone is usually fine and the app is listening to the wrong device, or something is blocking it. Check these in order.
- Stick drift: how to test and fix itYour character walks on its own or the camera slowly turns while you are not touching anything. That is stick drift. Here is how to measure it and what you can do.
- Keyboard typing wrong charactersYou press Shift+2 and get a quotation mark instead of @, or a quote mark waits for the next key before showing up. The keyboard is almost always fine: the system is using a different layout from the one printed on your keys.
