Microsoft 365 Help Test your microphone and speakers
Make sure you can hear other people and they can hear you.
Before you start
- A headset or working microphone and speakers.
- A webcam is needed only if you want video.
Follow these steps
-
Connect your headset
Connect your headset first. Keep only one device in the room using its microphone and speakers; two active devices can cause echo.
-
Open your meeting preview
In Teams, select Calendar, choose your meeting and click Join. The preview screen appears before you enter the meeting.
-
Allow microphone and camera access
If the browser asks, choose Allow for this Teams website. A blocked icon near the address bar means access may need changing in the site permissions.
-
Check the microphone and speaker
Choose Computer audio. Open the audio/device controls on the joining screen and select the headset microphone and speaker you want to use.
-
Check the camera picture
Switch the camera on briefly and confirm you can see yourself. Choose another camera if necessary. Turn it off again if you prefer a voice-only meeting.
-
Confirm sound with a colleague
The preview does not prove that the other person can hear you. Before an important appointment, arrange a short Teams call with a colleague and ask them to confirm your voice is clear.
-
Check the call in both directions
Ask the colleague to speak, then speak yourself. Adjust the computer volume and headset mute switch if needed. End the practice call with the red hang-up button.
-
Join when ready
Return to the real meeting preview and click Join now at the intended time. If access is still blocked, use the installed Teams app or contact IT.
You have finished when…
- You can hear sound clearly.
- Your recorded voice or colleague confirms the microphone works.
Helpful tips
- Check the physical mute switch on your headset as well as the Teams mute button.
- If you move to a different headset, repeat the check.
Something looks different?
No microphone sound
Check Teams device selection and Windows Settings > Privacy & security > Microphone. For web calls, also check the browser site permission.
There is echo
Use a headset, lower speaker volume, and make sure a second phone or computer is not also playing the same meeting.
