It's not your PC or laptop but the MS UAA is required on many systems before the audio driver or you don't get sound. You can read this at http://forums.cnet.com/7726-7587_102-2699006.html
Frankly I find installing XP today to be too much on today's owners. It was never easy and the passage of time has not made it better.
I have been to the manufacturers website and downloaded every driver that might possibly be the one i needed and no luck. So now i come to my fellow techies in need of some sever help i am actuall missing two drivers but only one is really important for me to sell this computer im working on. i need the sound driver for a IBM 8212 MUS Think Centre M52 and the name of the driver is IBM Lenovo ADI SoundMAX Audio Driver. It is for Win XP Pro Sp3. I really hope this helps becuse i could really use the help
