Install "Microsoft UAA High Definition Bus Driver" first and install the Audio Driver.

Your sound will work fine.

You can download drivers from the compaq support site.
An alternate solution is to use a driver update program to find and install missing or outdated device drivers.

To install audio / modem drivers, first download and install Microsoft Universal Audio Architecture (UAA) Bus Driver for High Definition Audio (sp32646):
