First check whether Windows 11 can see the microphone, then enable or select it; because updating the driver did not help, only reinstall the driver if the microphone remains completely undetected.
1. Check whether the microphone is detected and selected
- Open Start → Settings → System → Sound.
- Under Input, look for the internal microphone, often named Microphone Array or Internal Microphone.
- If it appears:
- Select it under Choose a device for speaking or recording.
- Open its properties and select Start test.
- Speak normally, select Stop test, and play the recorded sample.
- Increase Input volume if necessary. ^1^
If this test works, select the same microphone in the audio settings of the affected application instead of the webcam microphone.
2. Enable microphone access
Open Start → Settings → Privacy & security → Microphone, then turn on:
- Microphone access
- Let apps access your microphone
- The switch for the application you want to use
- Let desktop apps access your microphone for traditional desktop programs such as Teams or Zoom
Desktop applications are controlled through the combined desktop-app switch rather than individual switches. ^2^
3. Check for a hidden or disabled microphone
Do this before removing any drivers:
- Right-click Start and open Device Manager.
- Select View → Show hidden devices.
- Expand both:
- Audio inputs and outputs
- Sound, video and game controllers
- Look for Microphone Array, Internal Microphone, or another microphone device.
- If it is greyed out or disabled, right-click it and select Enable device.
- If it has a yellow warning icon, open Properties and record the error code—such as Code 10 or Code 43—before making further changes. ^3^
Also check for a physical microphone-mute key or privacy switch on the keyboard or laptop.
4. If Windows still shows no microphone, reinstall the audio driver
Updating a driver and reinstalling it are different operations. Reinstallation replaces a potentially incomplete or corrupted installation.
- In Device Manager, expand Sound, video and game controllers.
- Right-click the main audio device and select Uninstall device.
- If offered, select Attempt to remove the driver for this device, then choose Uninstall.
- Restart the computer. Windows should reinstall the audio device automatically.
- If it does not return, reopen Device Manager, right-click Sound, video and game controllers, and select Scan for hardware changes. ^1^
Removing the audio device temporarily disables audio until Windows reinstalls it, so note the device name before uninstalling.
5. Determine whether this is hardware-specific
If the internal microphone is still absent:
- Test an external USB or headset microphone.
- If external microphones work but the internal microphone never appears in Device Manager, contact the PC manufacturer with the exact model and any recorded Device Manager error code.
- If no microphone works, run Settings → System → Sound → Advanced → Troubleshoot common sound problems → Input devices. ^1^
