Got my audigy 2, confusion

I want to setup my speakers with the digital out port on the sound card, and the directions say for a 5.1 setup I need "4 pole miniplug to-4-pole miniplug digital cable". I know what this looks like, and I searched everywhere for it, and cannot find it. Can someone give me a link to where I can buy this.
I need this: click here with 4 poles.

Another thing that I found out during my research is that I can just use a single banded miniplug for the surround sound to work. Is this true?

 

If those are the directions for the speakers, you will most likely need the four pole plug. If it's not available at Radio Shack, contact the speaker manufacturer and ask for help locating one. I used the single pole to Coax connector to connect to my home theater system.

 

Yeah, thats what I have been hearing. I found on another forum that someone with the same soundcard and speakers used a single pole to coax and it worked. I am just afraid to go ahead with it with only the recommendation of one person. Is the system you have now 5.1? Is it going from your reciever or your soundcard?

 

I have an Aiwa 5.1 Dolby Digital receiver with Coax/optical inputs. I used a single pole 1/8 plug to coax plug from my Audigy2 cards digital output connected to my coax input on my receiver and it played all my DVDs in Dolby Digital 5.1 surround sound. You may need the 4 pole plug for gaming as I've heard the surround sound in games is recorded in a different fashion than movies. Here is the Audigy 2 manual http://files.americas.creative.com/manualdn/Manuals/2380/Audigy2.pdf and customer support so you can ask how to connect your particular brand of speakers to the card, if necessary http://us.creative.com//support/custsup/
