Microsoft Teams sound not working: nobody can hear you, or you cannot hear them

Most Teams sound problems are a mute somewhere — in the meeting or on the headset — Teams not being allowed the microphone, or the wrong speaker picked.

What you are seeing

In a Microsoft Teams call, people say they cannot hear you — or everybody else has gone silent for you.

The likely causes, most common first

Work down the list; most people find theirs in the first two.

1. You are muted in Teams

  1. Look at Mic in the meeting controls. A line through the microphone means you are muted; select it to unmute.

Microsoft: “If the mic icon has a line through it, you're currently on mute.” — support.microsoft.com/en-us/teams/meetings/my-microphone-isn-t-working-in-microsoft-teams

2. Your headset is muted

  1. Many headsets mute themselves when the microphone arm is pushed up, and many have their own mute button. Check both.

Microsoft: “Check that your headphone boom is not in the mute position” — support.microsoft.com/en-us/teams/meetings/my-microphone-isn-t-working-in-microsoft-teams

3. The computer has not allowed Teams the microphone

  1. On Windows: Settings → Privacy & security → Microphone, and switch on access for Microsoft Teams and for desktop apps.
  2. On a Mac: System Settings → Privacy & Security → Microphone, and tick Microsoft Teams.
  3. If they were on already, switch them off and on again, close everything and restart.

Microsoft: “Turn on the Let desktop apps access your microphone toggle.” — support.microsoft.com/en-us/teams/meetings/my-microphone-isn-t-working-in-microsoft-teams

4. The browser has not allowed it

  1. Using Teams in a browser, the browser has to allow the microphone as well. In Chrome that is Settings → Privacy and security → Site settings → Microphone.

Microsoft: “make sure your default browser settings allow Teams access to use your mic” — support.microsoft.com/en-us/teams/meetings/my-microphone-isn-t-working-in-microsoft-teams

5. You cannot hear them: the wrong speaker

  1. If you are the only one who cannot hear, look at your speaker. In Teams, Settings → Devices → Audio settings, and pick the speaker you are actually using.
  2. A Bluetooth headset that is flat, or still connected to your phone, will not appear. Charge it, disconnect it from the other device, and connect again.

Microsoft: “If you’re the only one who can’t hear them, there might be an issue with your speaker.” — support.microsoft.com/en-us/teams/meetings/my-speaker-isn-t-working-in-microsoft-teams

6. Test before the next meeting

  1. Teams has a test call under Settings → Devices → Make a test call: you record a short message and hear it played back. It is not there in Teams on the web.

Microsoft: “The test call feature is currently unavailable on Teams for web.” — support.microsoft.com/en-us/teams/meetings/my-speaker-isn-t-working-in-microsoft-teams
