Microsoft Teams Mic And Audio Not Working? Fix

You join a Teams call and your audio is silent, or your colleagues cannot hear you despite your mic being unmuted. This is usually caused by a mismatch between your Windows default sound devices and the configuration settings inside the Teams application.

Why this happens

Windows often toggles default sound devices after an update or when plugging in new hardware, causing Teams to point to the wrong output or input source.

Steps

1. 01
   Open the Start menu, type 'Windows Update', and click 'Check for updates' to download and install any pending system drivers that might be causing hardware conflicts.
2. 02
   Right-click the speaker icon in the bottom right of your taskbar and select 'Sound settings' to ensure your preferred speakers and microphone are selected as the 'Default' devices.
3. 03
   Open Microsoft Teams, click the 'three dots' icon near your profile picture, and navigate to 'Settings' then 'Devices'.
4. 04
   Manually select your headset or speakers under 'Speaker' and your microphone under 'Microphone' to ensure they match the default devices you just verified in Windows.
5. 05
   Restart your computer to allow the system to re-initialize your audio drivers if your device still does not appear in the Teams list.

Still not working?

If your microphone or speakers still fail to register, check the physical mute switch on your headset or cable, as these often bypass software settings. You should also verify that the Teams application has permission to access your microphone under 'Privacy & security' settings in Windows.

Frequently asked questions

Does this fix mean I need to reinstall Teams?

No, most Teams audio issues are configuration conflicts rather than corrupted installation files. Try these settings checks before attempting a reinstall.

Will changing these settings affect other apps?

Setting your default device in Windows Sound settings will update the audio source for most applications, ensuring consistency across your system.
