Summary

This guide helps you troubleshoot and resolve: How to Fix Windows 11 Not Detecting External USB Microphone for Microsoft Teams and Zoom Calls. Follow the steps below to fix the issue.

Common Causes

If your external USB microphone is not being detected by Windows 11, you may experience audio issues during Microsoft Teams or Zoom calls. This guide provides step-by-step instructions to help you identify the cause and restore microphone functionality.

Quick Fix Steps

1. Unplug the USB microphone from your computer and plug it back into a different USB port.
2. Restart your computer to refresh system drivers.
3. Check that the microphone is not muted via a physical switch on the device.
4. Ensure the microphone is selected as the default input device in your video conferencing app settings.

Detailed Instructions

Check Privacy Settings

Windows 11 includes privacy controls that can block apps from accessing your microphone.

1. Click the Start button and select Settings.
2. In the left sidebar, click Privacy & security.
3. Under App permissions, select Microphone.
4. Ensure Microphone access is set to On.
5. Ensure Let apps access your microphone is set to On.
6. Scroll down and verify that Microsoft Teams and Zoom have permission to access the microphone.

Set Default Recording Device

1. Right-click the speaker icon in the taskbar and select Sound settings.
2. Scroll to the Input section.
3. In the Choose a device for speaking or recording dropdown, select your USB microphone.
4. Click on the microphone name to open its properties.
5. Ensure the Input volume slider is not set to zero.
6. Speak into the microphone and check if the blue input bar moves to confirm it is picking up audio.

Run the Windows Audio Troubleshooter

1. Open Settings and go to System.
2. Select Troubleshoot, then click Other troubleshooters.
3. Find Recording Audio and click Run.
4. Follow the on-screen prompts to detect and fix issues.

Troubleshooting

Update or Reinstall Drivers

1. Right-click the Start button and select Device Manager.
2. Expand the Audio inputs and outputs section.
3. Right-click your USB microphone and select Update driver.
4. Choose Search automatically for drivers.
5. If the issue persists, right-click the device again and select Uninstall device.
6. Unplug the microphone, restart your computer, and plug the device back in to allow Windows to reinstall the driver.

Test in Another Application

To determine if the issue is with Windows or a specific app, test the microphone using the built-in Voice Recorder:

1. Click Start and search for Voice Recorder.
2. Open the app and press the record button.
3. Speak into the microphone and then play back the recording.

If the recording works, the issue is likely within the settings of Microsoft Teams or Zoom rather than Windows 11.

Note: If you are using a USB hub, try plugging the microphone directly into the computer. Some hubs do not provide enough power for external audio devices.

Warning: Avoid using third-party "driver updater" software, as these can often install incorrect or incompatible drivers that cause further system instability.
