trying to wire pc audio out to a surround sound with aux in L & R rca style

[northerngames]

Hi I am trying to figure a way to wire my pc sound to travel through my surround sound system.

the pc audio out is the normal green circle on the motherboard that normal pc speaker's hook to so that is the out I am dealing with.

now on the back of the surround reciever my only opton is AUX1 & AUX2 and they have the L & R IN jack's on each side but they are the RCA style type plug's.

so I am trying to find a link or tutorial or part that allow's the regular pc speaker cord to be split into 2 rca jack's.

I also have a S/PDIF-out coaxial on the motherboard but the reciever does not have that option unfortuniatly but can a rca splitter be plugged into it and then split down into the input L & R on the reciever's RCA input jack's that way or no?

any picture's link's or tutorial's on how to do this or even part's from some where and I do not really care what or how it is done I just need to figure out something or I will need to redo my whole sound idea for the cab.

He's correct ....except....that he is showing a MONO 1/8" plug on one end.
(just wanted to clarify this)

You need to make sure you get the STEREO version that has three silver areas and two black stripes.

Should be able to get them at radio shack as mentioned or at least the parts to make one.
