How to Set Default Microphone in Microsoft Teams
You set your default microphone in Microsoft Teams directly within the app’s settings. This process ensures your chosen audio input device is automatically used for all your calls and meetings.
Microsoft Teams, a popular collaboration platform, requires you to specify your preferred microphone to avoid audio issues. Having the wrong mic selected can lead to poor call quality or silence for other participants.
For example, if you connect a high-quality headset to your Windows 10 PC and also have your laptop’s built-in microphone active, you’ll likely want Teams to use the headset. Setting it as default guarantees your audience hears you clearly every time.
Select your preferred microphone from the Microphone drop-down menu in the Devices settings within Microsoft Teams. Click the three dots (…) next to your profile picture, then choose Settings, and navigate to Devices to make the selection.
How to change your microphone in Microsoft Teams
Changing your microphone in Microsoft Teams is simple. Open the Teams app, go to Settings, and then select Devices to see your audio options.
You can also open the app from the Taskbar or Taskbar overflow.

Once the app is open, look for the three dots (…) next to your profile picture. Click them and select Settings.

On the left side of the screen, click on Devices. Look for the section labeled Audio settings. Use the drop-down menu under Microphone to select the device you want to use.

Note: You do not need admin privileges to change these settings. Any standard user account can adjust these preferences.
