If your Windows sound is not working and it’s due to having missing or corrupt sound drivers you can often find the sound drivers you need with Windows Update.
Use Windows Update to find the sound drivers you need
STEPS 1 & 2: Open Windows Update through your Start Menu and typing “Windows Update”. Click on the Windows Update icon/link to open it.
STEPS 3, 4, & 5: Once on the Windows Update screen you should see any updates if they are available. In the example, there are important updates and optional updates. Click the links to view details about these updates. Often drivers may be a part of the update. Click on the button Install Updates. Note: you may need to restart your computer to apply changes.
