nf4 ultra-d and NO SOUND!?!?!?!

I just got done putting together my new comp, and I have NO sound!?!? What driver am I suppose to install, the nvmixer one or the realtec one?!

all i do is download this
http://www.nvidia.com/object/nforce_nf4_win2k_6.86.html

and install it and works fine, has internet drivers, sound drivers, etc newest nforce 4 driver

Thanks, I forgot that nvidia usually has more up to date stuff then what is on dfi's site. Thanks!

Well I comfirmed I am stupid. I plugged in the wrong connectors (not ac97) into the "front audio" thing on the MB and I guess it didn't like it...

My sound is back, sorry for being stupid! lol
