How to check your microphone and camera before a meeting

Most meeting trouble is small. The wrong microphone is chosen. The camera is blocked by a privacy setting. You join with your mic live when you wanted it off. All of it can be sorted a few minutes early, before anyone is watching.

This guide shows how to check your microphone and camera before a meeting on Windows and on Mac, and how to mute yourself so you join quietly. Then it shows how to ask Key to do the opening and clicking for you.

Check your microphone on Windows

Windows has a built-in microphone test, so you do not need to start a call to find out whether you can be heard.

1. Open Start › Settings › System › Sound.
2. Under Input, pick the microphone you plan to use. If you have a headset and a laptop mic, make sure you choose the right one.
3. Under input settings, select Start test and speak normally.
4. Select Stop test, then choose Play to hear your recording.
5. If it is too quiet or too loud, move the Input volume slider and test again.

If the microphone does nothing at all, the cause is often a privacy setting. Open Settings › Privacy & security › Microphone and make sure Let apps access your microphone is turned on.

Check your microphone on Mac

1. Open the Apple menu, then System Settings › Sound.
2. Click Input and choose the microphone you want from the list.
3. Speak and watch the input level meter move. If it stays flat, that device is not hearing you.

Next, check that your meeting app is allowed to use the microphone. Open System Settings › Privacy & Security › Microphone and switch the app on in the list.

Your Mac also shows a recording indicator in Control Center when the microphone is in use or has been used recently. It is a handy way to see whether an app is listening.

Check your camera on Windows and Mac

The easiest test is to open a simple camera app and look at yourself. No call needed.

On Windows

1. Open the Start menu, type Camera and open the Camera app.
2. Check that you can see yourself, and that the picture is well lit and framed.
3. If you see a black screen or an error, open Settings › Privacy & security › Camera and make sure camera access is turned on, including for your meeting app.

Some laptops also have a physical shutter or a function key that switches the camera off. Check that too.

On Mac

1. Open Photo Booth or FaceTime. These built-in apps already have camera access.
2. Look for the green light beside the camera and check your picture.
3. If your meeting app shows no picture, open System Settings › Privacy & Security › Camera and switch that app on.

If your meeting runs in a web browser, the browser asks for permission the first time. On Safari, you can change this in its settings under Websites.

Mute yourself before you join

Most meeting apps show a preview screen before you enter. It usually has a microphone button and a camera button, and a small level bar for your voice. Use that screen as your final check.

• Turn the microphone off if you want to join quietly. You can turn it on when it is your turn to speak.
• Leave the camera on only if you are ready to be seen.
• Speak a word and watch the level bar. If it moves, the right microphone is chosen.

Muting inside the meeting app is the safest choice, because the app then shows everyone, and you, whether you are live. Many laptops also have a microphone key in the top row. Its light usually tells you the state, but the app is the one to trust.

A quick checklist

• The right microphone is selected, and your recorded or spoken test sounded clear.
• The right speakers or headphones are selected. If the output is wrong, see how to change the volume and sound output device on your PC.
• Your camera picture is bright enough and your background is fine.
• The meeting app has permission for both the microphone and the camera.
• You are muted until you are ready.

Ask Key to open the settings for you

If you would rather not hunt through menus, you can ask Key. It is a free assistant that sits at the top of your screen. You can speak to it or type to it, and both give the same result. It opens the real window and presses the real button, shows a small panel while it works, and you can stop it at any point.

For a pre-meeting check, ask it to open the sound settings or the camera app, so you are looking at the right screen in seconds. Then you do the part only you can do: speak, look at yourself and decide what sounds right. If you want it to tidy other things first, it can also handle jobs like changing settings by voice.

Open my sound settings and the Camera app

Both are open: check your input there and your picture in the Camera app.

Checked: the sound settings and the Camera app are both open on screen.

Key tells you what it did and reads the result back before it reports it. If it could not check something, it says so.

Common questions

Why can people not hear me even though my mic looks fine?

The meeting app may be using a different microphone from the one you tested. Open the app's audio settings and choose the same device you picked in Windows or on your Mac. Also check that you are not muted in the app.

Why is my camera black?

Another app may already be using it, or a privacy setting may be blocking it. Close other video apps, then check the camera permission described above.

Should I test before every meeting?

Only when something has changed: a new headset, a new app, a system update or a new room. For a regular call on the same setup, the preview screen is enough.
