When you inadvertently delete a sound driver, don't panic. You can reinstall the driver. Sound drivers can often be mistaken for an unnecessary driver and uninstalled. The sound card driver is used by the computer to project the sounds made in video, conversations or recorded audio. Fortunately, a sound driver is software and this software is either still on your computer, on a CD in your home or can be downloaded from the Internet.
