MS Teams - microphone not working

Hi everyone,

I've been having issues with the MS Teams desktop app since I updated to Mac Mojave last November. When in a call, my camera and speakers work, but my microphone doesn't work (either the internal Mac or any external headset).

I'm using Mac Mojave 10.14 and MS Teams (updated on 10/12/2018).

Any other communication platform (Skype, WebEx, etc) work.

Thank you for your help.

Hello Carlos,

If you are encountering microphone not working issue when using Teams on your Mac, please kindly try the following:

1. Open System Preferences.

2. Click on Security & Privacy> Select the Privacy tab.

3. Select Microphone on the left bar and verify the Microsoft Teams has permissions:

If it was already enabled, you can try unchecking it and reboot your Mac, then enable it to see if it can help.

If the problem persists, I would suggest you reinstall Teams and check the results. Besides, may I know if this problem happens to all callings and meetings in Teams?

Note: Please back up your data before installing to prevent data loss.
