did you install the chipset driver? if not, do so first. - then install all the other drivers.
find all drivers for xp here :
The Dell site may be reporting the wrong driver. It happens...
Go to start - programs - accessories - system tools - system information.
Click on "components", then on "problem devices". Your sound card will be listed there. Check the device and vendor number in the first line (DEV ....  VEN ....   ). Look those numbers up here:


This will identify the chip. Check the manufacturer's website, or try a driver database like Driverguide:


Good luck!
