HP Pavilion G6-2288Se XP Aduio Driver not working

Hello ,

I have just bought HP Pavilion G6-2288Se notebook. Specifications here :

http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&dlc=en&docname=c03647602&lc=en&jumpid=reg_r1002_usen_c-001_title_r0001

This model comes with no Operating System installed . So I decided to install Windows XP.

The installation went well . And after that I installed my drivers

Intel HD Graphics : intsalled and works well

Realtek Eathernet : installed and works well

USB Devices : works well

HP Camera : identified

All except IDT High Definition Audio

I downloaded the driver from HP , but it didn't work .

I used vista driver from HP , but it didn't work.

I downloaded IDT XP driver 2007 and 2009 versions from Microsoft Update Catalogbut also didn't work

I used Device Manager>install from a specific location>Don't search>select hardware type :sound>Manufacturer

>IDT    and also another time used Have Disk

but also did not work .

what should I do ?

Please Please help me

thanks
