Getting 5.1 Sound

Hey - here's the situation I'm in:

I have 5.1 speakers called Z-640 from logitech, which are extremely popular among computer users for computers, only they work with other audio sources too. Here's the thing - it came with an adapter to change two of the three 1/8 inch colored connectors into two RCA jacks, one each (top left of image).

My question is, I know this adapter allows for only 2 channels, but want to get 5.1 out of this. Now, there's three 1/8 inch plugs that it comes with, so it mathetmatically it would make sense that they each carried two channels, and therefore 5.1.

My question is, how do I get 5.1 out of this? I have an infinite supply of 1/8 to rca adapters.

I think there's an optical cable plug-in on that set-up... that's how you get 5.1

No, there is no optical in, yet the speakers are advertised as 5.1.

forgot you need to register so here's the final verdict.

"Yeah. the z640 does not have a digital decoder for DD.

You need to buy an external receiver for it to use it with Xbox, or you can directly hook it up to a PC sound card that has DD decoding. Sorry, buy 50 dollar speakers and don't expect a decoder!"

I mean this in the best way, but Sometimes I think the people around here want to buy a new piece of equipment for everything...(the people on xbox forums, too).

The speakers DO work with Xbox. Xbox has two-channel line out RCA, and the z640s have an adapter for 2-channel line in RCA. It's advertised in the manual AND on the box for the z-640s.

I guess what my main question could be divided down to is 'how are these three 1/8 inch plugs divided into 5.1 channels?'. I'm not sure who posted that on those forums, because I'm not registered, but they are basically an idiot. The z-640's advertise right on the box that they have a dolby digital decoder.

I'm sorry if this sounded at all offensive. If there's no clear-cut way the 1/8-inch plugs are divided, what are some steps I could take to figure it out?

i just bought some X-350's and am having the same problem you are...

the manual DOES state that:

Green = Front Left/Right
Black = Read Left/Right
Orange = Center/Sub


right now i'm trying to find an optical out ----> 5.1 adapter to get REAL 5.1 out of it...
