Enable onboard sound through Device Manager.
Onboard sound and video cards are devices built into the motherboard that allow you to use these features without installing peripheral devices on a computer. Sometimes peripheral devices are installed that override the built-in devices on a motherboard. Should an installed sound card malfunction, you can revert to the onboard sound by disabling (turning off) the corrupt device.
Device Manager is a utility for the Windows operating system that allows you to monitor performance of hardware in your computer. Device Manager allows you to choose among devices, enabling or disabling the ones you wish to use. You can disable a corrupt sound card and revert to onboard sound until you install a new card.
