It depends on which sound you have, the Integrated (on the motherboard) sound or an optional SoundBlaster sound card. The SoundBlaster driver as listed is only an update. But, if you go to www.creative.com you can download the Dell drivers for that model sound card (you must use Dell SoundBlaster drivers, not the regular Retail SoundBlaster drivers).
Also, did you install the Intel Chipset Drivers? They MUST be installed before installing the sound drivers. (Install sequence is (1) Install Windows (2) Install Chipset Drivers (3) Install Device Drivers such as sound, video, etc).
