k here's what I did for COMPAQ PRESARIO SR2020NX
XP Home Edition

Fall 2006 Original Realtek High Definition Audio Drivers
Download sp26792

Universal Audio Architecture UAA High Def Bus Driver

Universal Audio Architecture UAA High Def Bus Driver
========================================================

It told me in order to install 26792 that I needed UAA first, but even after I installed the UAA it gave me the same message so I dunno why it isn't working plus also it is next to impossible to uninstall the realtek high def drivers even if I wanted to.

Frustrated again...
