MS UAA must be installed before Audio. MS UAA > here MS UAA for XP SP3,> here
Conexant High-Definition SmartAudio 221 Driver >here
Unzip to a folder..use Device Manager,right click "Audio Device on HD",choose Update driver,
No to connect, Install from a list or specific location,
Select Don't Search, I will choose the driver to install,
For the Hardware Type select 'Show All Devices'
Remove the check from "Show Compatible Hardware" and click on "Have Disk".
Next...browse to the unzipped folder and choose the "WiSVHe5.inf".
Ignore XP when it complains, Reboot.
