Solution 1: Uninstall your audio driver
Uninstalling your audio driver has pretty good chances of getting your microphone to start working again. Don’t worry about uninstalling your audio driver as your computer will automatically reinstall it once you reboot. Right-click on the Start Menu button to open the WinX Menu. Click on Device Manager in the WinX menu.
Double-click on Sound, video and game controllers to expand that section. Locate your audio driver (Realtek High Definition Audio – for example) and right-click on it. Click on Uninstall. Restart your computer.
Once your computer boots up, your audio driver will be detected and reinstalled automatically, and your microphone should start working again after that happens.
Solution 2: Make sure that your microphone has been enabled
Right-click on the Volume icon in the system tray and click on Recording devices.
Right-click on an empty space in the window and make sure that both the Show disconnected devices and Show disabled devices options have check marks beside them. If one or both of them don’t have check marks, click on them and they will be enabled and check marks will be placed beside them.
Right-click on Microphone and click on Properties.
Make sure that the dropdown menu in front of Device usage is set to Use this device (enable). If it is set to don’t use this device (disable), click on the dropdown menu to open it and click on Use this device (enable). Click on Apply and then on OK on your way out. Now check to see if your microphone has started working.
Solution 3: Disable any and all audio enhancements
If you have any audio enhancements enabled on your computer, they may be messing around with your computer’s microphone and causing it to not work. If that is the case, you can go here and perform Solution 4 to disable any and all audio enhancements that have been turned on, effectively fixing the issue.
Solution 4: Switch to Windows’ generic audio driver
If none of the solutions listed and described above work for you, there is a pretty good chance that switching to Windows’ generic audio driver – an audio driver that all computers running on the Windows OS come with by default – will get your microphone to start working again. To stop using your computer’s audio driver and start using the generic Windows audio driver, go here and perform Solution 3.
