Yes,
The ASUS Z7N8X deluxe has sound build on the mobo.
I was never able to get the sound drivers to re-install after re-installing WinXPPro so I reformatted HD and did a complete install of WinXP Pro.
I kept receiving message when trying to reinstall drivers that the hardware could not be installed and something to the effect that "Access is denied".
What a pain.
