Setting up the bios with an Asus X99a for DAWS?

Been trying to research this, but drew a blank. I have not even found out how to disable the on board sound.

Can anyone give a few tips on how to get the most out of my X99a Mobo for Daw purposes. I think I have done what is required in |Windows 10.

Does anyone know, or know of a site that deals with this for new Asus bios?
