Fix Microsoft Teams Audio Not Working on Windows

Joining a meeting only to realize you cannot hear the participants or they cannot hear you is incredibly frustrating. This is usually caused by a mismatch between your Windows default sound devices and the specific hardware selected within Teams.

Why this happens

Windows often defaults to the wrong output or input device after an update, or Teams fails to sync with your current system settings.

What you'll need

Ensure your headset or speakers are plugged in and recognized by your system before beginning these steps.

Steps

1. 01
   Open the Start menu, type 'Windows Update', and select 'Check for updates' to install any pending patches.
2. 02
   Right-click the speaker icon on your taskbar and select 'Sound settings'.
3. 03
   Under 'Output', ensure your preferred headset or speakers are selected as the default device.
4. 04
   Under 'Input', ensure your primary microphone is selected as the default device.
5. 05
   Open Microsoft Teams, click the three dots icon near your profile picture, and go to 'Settings'.
6. 06
   Navigate to the 'Devices' tab and verify that the 'Speaker' and 'Microphone' dropdowns match the devices you set in Windows.
7. 07
   Restart your computer if the audio remains silent after updating the settings.
