just thought i would pass this along.
after purchasing a pair of GTX460-OC cards ( and spending a butte load of cash ), there can be a conflict with bios on mobo. the video cards come with HD sound of thier own which the mobo see's as a sound card disabling its onboard audio. as it seems, my mobo can only "enable" or "disable" its onboard sound lacking an option of "enable" or "yes" or something to that effect leaving me with ........."no audio device" installed. firmware updates speak nothing of this fix so why bother. further more, there is no more room for expansion of an additional sound card on the mobo because the sli takes up the entire bays!
buy a new mobo w/bios options
buy new video cards maybe cheap ones
use a single card and add sound card
have i missed any other possible fixes? why do video cards have hd sound when the onboard is great? perhaps the mobo manual may show a jumper that can disable the onboard sound out of the bios?
boned, benched, and bummed. reminds of back in the day with dos and sierra titles. thought we came farther than that.
