nf7 sound... how to get 5.1 ?

Is there any sound utility for nf7's sound card ? How do you get it to get sound through all the outs? I tried plugging another set of stereo speakers (sort of) in the sub out and rear and it does nothing.. no sound comes from them? Is it because these speakers are not subwoofers or rear speakers (or something)? Or should i setup something?

The NF7-S should have the soundstorm utility that comes with the nForce driver set. If you have the NF7 non-s, then you might try checking either the sound section under control panel or checking realtek's site to see if there's some kind of utility for the ALC650 codec.
