Hi,

You need to install the Microsoft UAA bus driver. Until then, Audio doesnt work on XP. Luckily, HP has that driver on their website.
You can download UAA driver installation file(sp26334.exe) from the below link:

This model of Presario has an audio controller that supports the high definition audio. You need to have Microsoft Universal Audio Architecture (UAA) Bus Driver for High Definition Audio installed on the computer before installing the audio driver.

Microsoft Universal Audio Architecture (UAA) Bus Driver for High Definition Audio Driver:

If the above did not work, please try the alternate ones given below.
