Hi did you do a fresh install of the OS? if so in where did you the drivers form and in what order did you install them?
If it isn't a fresh install of the OS, why are you trying to install the audio drivers?
Is you XP installation disk an SP2 or SP3? or have you integrated SP3 your self?
I wouyld suggest you do a fresh install, with SP2 if possible, and before doing any windows updates install teh drivers from the web site in this order: chipset audio video LAN anything else
Also check audio is enabled in BIOS
