HP never shipped this laptop with Windows XP, hence they don't offer any official support for it in Windows XP.

Check these links to find the UAA driver and download it first. Or you can search the HP website for kb888111.exe

You will need to install the UAA driver first.......

Then you will need to install the IDT/Sigmatel audio driver from one of the links below:

Remember that laptops cannot normally use generic drivers like Desktops can. That's just the way laptop makers build them.
