Send it back to an earlier time when the sound worked. If that doesn't work, check the device manager and see if there is a problem with your sound card. Go the the control panel then system. Click on hardware then device manager. Scroll down the list to sound, video and game controllers. Look and see if the is a yellow question mark located next to your sound card. Write down the name and model number(if listed)in case you need to find new drivers. I'd suggest you uninstall the sound card, reboot the computer and let Windows reinstall it. If that doesn't work, try downloading new drivers from the sound card manufacturer or the maker of your computer.
