Go to intel site and download drivers for the on board sound chipset, might be Realtek, or similar, but make sure it's for your make and model.
I have just bought a new PC built by a friend. Mother board is intel D945GTP with NH82801 chipset and 2 x 512 DDR2 RAM 533mhz FSB. It also has an nVidia GeForce 6600GT Graphics card.
We have installed XP Home and Office2003.
We cannot get the onboard Audio to work and keep getting the annoying error box hDevice=ffffffff. When we run the Installer Driver CD it says the Graphics Accelerator and Audio "Failed".
Can anyone help PLEASE!!!!!
