Disablbling Souind on A8R-MVP

[unwashed potato!]

i have a Asus A8R-MVP Crossfire mother board and just put a new sound card on it but it doesnt seem to be working. I think it may be because on-board is still turned on in the bios. How do i turn off on-board sound in the bios?

I have looked and found some on-board lan, and on-board IEEE1394, and on-board HD. thats about all outa the slection that i could imagine it would be.

Anyione know

and on-board HD.

Thats the one you need to turn off, guess you may have sorted this by now but thought i'd say anyway
