Dear @Sue Briggs,
I understand how frustrating it can be when your microphone suddenly stops working during your Teams meetings, and I am here to help you get this resolved. To help me pinpoint the exact cause and provide you with the correct fix right away, could you please provide a little more context by answering these quick questions?
- Which device are you using? Are you experiencing this on a Windows PC, a Mac, or a mobile device (iOS/Android)?
- Are you using the Microsoft Teams desktop application, or are you accessing Teams through a web browser (such as Microsoft Edge or Google Chrome)?
- Are you seeing any specific error codes (for example, a code starting with "0x" or a specific correlation ID), or does Teams display a banner message like "We couldn't find a microphone" or "Your microphone isn't working"?
- What kind of microphone is it? Is it the built-in microphone on your device, a USB headset, or a Bluetooth wireless device?
- Are you seeing an error message? Does Teams show a specific banner like "Your microphone isn't working" or "We couldn't find a microphone", or is it just completely silent?
- Is anyone else affected? If you are using a work or school account, are your colleagues experiencing similar issues, or is this only happening on your account?
In the meantime, please try the following official troubleshooting options which usually resolve issues with basic issues:
- Verify your microphone is not physically muted (check your headset or laptop for a mute switch) and that your connection is secure.
- Ensure your operating system permits Teams to access the microphone.
- Windows: Go to Settings > Privacy & security > Microphone. Ensure "Microphone access" and "Let desktop apps access your microphone" are toggled On.
- macOS: Go to System Preferences > Security & Privacy > Microphone and ensure Microsoft Teams is checked.
- Windows: Go to Settings > Privacy & security > Microphone. Ensure "Microphone access" and "Let desktop apps access your microphone" are toggled On.
- Teams Device Settings:
- In a meeting, click More > Settings > Device settings.
- Confirm the correct microphone is selected in the "Microphone" dropdown.
- Use the "Make a test call" button to verify if the microphone is capturing audio correctly.
- Ensure both Microsoft Teams and your operating system (Windows/macOS) are updated to the latest versions.
For detailed, step-by-step instructions including browser-specific settings and driver troubleshooting, please refer to the official Microsoft support guide: My microphone isn't working in Microsoft Teams | Microsoft Support
