Microphone not working when using Teams

Hello, thank you for reaching out to Microsoft Q&A.

Could you please confirm whether your microphone works normally outside of Microsoft Teams?

1. Open the Windows Sound Recorder app.
2. Record a short voice clip.
3. Play it back.

If you can hear the audio, your internal or external microphone is working properly, and the issue is likely with Microsoft Teams.

However, if you do not hear anything, the problem is likely with the internal microphone.

=================================================================

Please let me know the following so we can troubleshoot further:

• Are you using Microsoft Teams on the web, the Windows desktop app, or the iOS/Android app?
• Are you using an external headset/microphone or your laptop’s built-in microphone?
• Does the microphone work correctly in other apps outside of Teams?

Your answers will help us troubleshoot the issue more quickly.

Try these steps in order to restore microphone audio in Teams:

1. Make sure mute is off

• In the meeting controls, check the Mic icon.
• If it has a line through it, select it to Unmute mic.
• Also check for a physical mute switch or button on the headset or external mic and ensure it is not muted.

2. Verify Teams is using the correct microphone

• In Teams, select Settings and more (…) > Settings > Devices.
• Under Audio settings, open the Microphone dropdown and select the correct mic.
• Select Make a test call, follow the Test Call Bot instructions, and confirm the playback can be heard. If not, change the device in the dropdown and test again.

3. Check Windows privacy settings for the microphone

• Open Settings from the Windows Start menu.
• Go to Privacy & security > Microphone.
• Turn on Microphone access.
• Turn on Let apps access your microphone.
• Turn on Microsoft Teams (work or school).
• Turn on Let desktop apps access your microphone.
• If these were already on, toggle them off and back on, then restart the device.

4. Confirm the microphone is enabled and has input in Windows sound settings

• Open Settings > System > Sound.
• Under Input, select the mic under Choose a device for speaking or recording.
  • If it does not appear, use Add device to pair/connect it.
• Next to Volume, ensure it is not muted and is turned up.
• If still not working, go to Advanced > More sound settings.
  • On the Recording tab, right‑click the mic and select Enable if it is disabled.

5. If using Teams in a browser, allow mic access in the browser

• In Microsoft Edge:
  • Go to Settings and more (…) > Settings > Cookies and site permissions > Microphone.
  • Turn on Ask before accessing (recommended).
• In Google Chrome:
  • Open Settings > Privacy and security > Site settings > Permissions > Microphone.
  • At the top, select the correct device from the dropdown.
  • Under Default behavior, select Sites can ask to use your microphone.

6. Check remote desktop settings (if using Teams over Remote Desktop)

• From Start, search and open Remote Desktop Connection.
• Select the Local Resources tab > Settings… under Remote audio.
• Under Remote audio playback, select Play on this computer.
• Under Remote audio recording, select Record from this computer.
• Select OK and reconnect.

7. If the mic still does not work

• Ensure Windows and Teams are fully updated.
• If the internal or external mic is still not detected under Input devices, follow the guidance to check and update audio drivers.
• As a temporary workaround in meetings, use Call me back in the Teams meeting join screen to have Teams call a phone and use the phone’s microphone for audio.
