There a number of places you can check your sound...

The following instructions are for Windows 10.

You can now do a test call in the Microsoft Teams Desktop App.

  1. Click on your profile picture and choose Manage Account
  2. Your current Audio devices will be displayed, which you can change, and you can perform a test call

1. Check System Sound settings on the sound icon

Right click on the speaker icon and choose Open Sound Settings

Choose the correct output and Input for your sound - if you are not sure which, experiment

2. Check Device Settings in your Teams Meeting

On the call bar, click on the three dots and choose "Show device settings"

You will see the options to adjust your device settings

3. Still unsure how to get audio output and input

This may be a driver issue of your device.

Workaround - use a mobile headset - this will likely get you going.
