How to Set Default Microphone in Microsoft Teams
You set your default microphone in Microsoft Teams by adjusting settings within the app itself, ensuring your preferred audio device is always selected for calls and meetings.
Microsoft Teams is a powerful collaboration tool, and selecting the correct microphone prevents audio issues where callers might hear background noise or nothing at all. This is crucial when you have multiple audio input devices, such as a built-in laptop mic, a webcam mic, and a dedicated headset, connected to your PC.
For instance, if your headset microphone offers superior audio quality over your laptop’s built-in mic, you’ll want to ensure Teams defaults to that headset. Successfully configuring this setting means your chosen microphone will be used consistently for all your Teams communications without needing to re-select it each time.
How to change your microphone in Microsoft Teams
First, open the Microsoft Teams app. You can find it in your Start menu under your list of apps.

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.
Summary
- Easy Access: You can quickly change your audio setup through the Settings menu in Teams.
- Multiple Devices: If you have more than one microphone plugged into your PC, you can easily toggle between them.
- Better Sound: Selecting a high-quality external microphone will make your voice much clearer during your calls.
