Have you checked what the status of your sound device is in Device Manager? Have you attempted to uninstall its current driver, uninstall the device itself, and then perform a Scan for New Hardware to see if a newer/better driver is available? If that didn't work, have you first checked the support site for your computer manufacturer to see if they have an updated driver and, if not, the manufacturer of the sound card?
Give all these things a try at a minimum before declaring the hardware dead.
