sound chip trouble

Board: Asus A7V-VM 1.02
OS: ME

i have no sound, the only driver under sound video and game controllers is Crystal WDM Audio Codec (with a !), i think my problem is that i dont have an audio controller under display adapters, all i have there is Trident 9685/9680/9682/9385/9382/9385-1 PCI [Display adapter].

Please help, Cs 1.6 is wayyy harder without sounds

by the way the error message on the Crystal WDM Audio Codec is Code 10

thanks, but what do i do with this file?

there is no sound driver to update, none in sound video and game controllers or display adapters

i dont know how to just add a driver but i dont have a driver to update to the one you told me to download
