Try these steps in order:
- Check microphone privacy access.
- Windows 11: Start > Settings > Privacy & security > Microphone.
- Turn on Microphone access and Let apps access your microphone.
- If the problem is in one app, make sure that app is also allowed.
- Windows 10: Start > Settings > Privacy > Microphone.
- Turn on Allow apps to access your microphone and Allow desktop apps to access your microphone.
- Make sure the built-in microphone is selected as the input device.
- Windows 11: Start > Settings > System > Sound > under Input, choose the device for speaking or recording.
- Open the device properties, select Start test, speak, then Stop test and Play. If the test records sound, Windows is detecting the microphone.
- Windows 10: Start > Settings > System > Sound > under Input, confirm the microphone is selected in Choose your input device. Speak into it and check Test your microphone.
- Increase microphone input volume.
- Windows 11: Start > Settings > System > Sound > select the microphone > adjust Input volume.
- Windows 10: Start > Settings > System > Sound > Input > Device Properties > Levels tab, then raise Microphone and Microphone Boost.
- Run the built-in audio troubleshooter.
- Windows 11: Settings > System > Sound. Scroll to Advanced and use Output devices or Input devices under Troubleshoot common sound problems.
- Windows 10: Settings > Update & Security > Troubleshoot > Additional troubleshooters > Recording Audio.
- Reinstall the audio driver if Windows is not detecting the microphone.
- Right-click Start > Device Manager.
- Expand Sound, video and game controllers.
- Right-click the audio device and select Uninstall device.
- If shown, select the option to remove or delete the driver for this device.
- Restart the PC.
- If Windows does not reinstall it automatically, return to Device Manager, right-click Sound, video and game controllers, and select Scan for hardware changes.
- Then right-click the audio driver and select Update driver.
- Check Windows Update for driver updates.
- A Microsoft Q&A accepted answer recommends installing available driver updates from Settings > Windows Update > Advanced options > Optional updates, then restarting.
If the speakers work but the built-in microphone still fails after these steps, the remaining likely cause is an audio driver issue or a hardware problem with the internal microphone.
