How to fix microphone which does not work on Teams

Answer 1

Dear @Meltor, Gavin R, 

Thank you for posting your question in the Microsoft Q&A forum.   

As a moderator, I don't have the tools to investigate your specific tenant directly because this is a user-to-user support forum. Moderators and contributors, including external Microsoft employees, cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas. However, I will try my best to guide you as clearly as possible.  

To help me assist you better, could you please help me answer a few questions below:  

Does your microphone work on other apps? Please help me test that. 

Are you using the Teams web version or the desktop app? Does this issue happen on one or both? 

Have you tried unplugging it and plugging it back in yet? 

In the meantime, please help me check the settings below: 

In Windows: Go to Settings > Privacy & security > Microphone. Ensure "Microphone access" is set to On and that Microsoft Teams is included in the permission list below. 

If the issue occurs on the web: Please try a different browser. Log in there and try a meeting to see if the browser asks for permission to allow the microphone. If you allow it, does the mic work then? 

If the issue occurs on the app: Please go to Settings > Devices > Make a test call and check if the mic works there. Additionally, ensure the microphone setting has the correct device selected. 

Please answer the questions above and check those settings for me. I will use that information to understand your specific case and assist you better. 

Answer 2

To fix a microphone that does not work on Microsoft Teams, you can follow these troubleshooting steps:

1. Check Power Supply: Ensure that the microphone is powered on and connected to a power supply if required.
2. Inspect USB Connection: Make sure the USB cable is securely connected at both ends. If the connection seems faulty, try replacing the cable.
3. Firmware Issues: If the microphone was recently updated, a firmware issue might have occurred. Try resetting the power on the device. If problems persist, contact the manufacturer to ensure the firmware is up to date.
4. Avoid USB Extenders: If you are using a USB extender, consider removing it, as it can cause issues with audio devices. If necessary, ensure the extender is compatible with your microphone.
5. Audio Settings in Teams: Check the audio settings in Teams to ensure the correct microphone is selected. Go to Teams settings > Devices and select your microphone from the list.
6. Windows Sound Settings: Open Control Panel > Hardware and Sound > Sound. Under the Recording tab, ensure your microphone is enabled and set as the default device.
7. Check for Muted Microphone: Ensure that the microphone is not muted at the system level or through any physical mute switch on the device.
8. Test with Another Application: Try using the microphone with another application to determine if the issue is specific to Teams or a broader hardware issue.

By following these steps, you should be able to resolve most microphone issues in Microsoft Teams.
