Tweaking my speaker setup

Im kinda getting tired of just having my rear and side speakers just sitting around so im going to mount them soon and need to find a way to change the volume of individual speakers since it will be really hard to hear them once mounter (on the ceiling). Ive tried the Creative software that came with my sound card (audigy 2 LS/value) and i cant seem to find the right place to do that. When i was installing the software however, one of the backgrounds of the installer showed something that looked like what i need but i cant find it anywhere! the creative website isnt much help either so ill just keep looking until i figure it out so any help would be appreciated

 

ok i found this driver that allows me to do that pretty much but it says it doesnt fully support EAX which in modern games is kinda a must have Its called kX Audio Driver and the sound TOTALLY kicks the Creative drivers butt lol, its just amazing. Im kinda skeptical about using non-creative drivers tho but if this is my only choice then i guess ill have to make do. Plz, if you have any other suggestions or ideas please contribute since i want my EAX!
