5.1 Audio with 3 jacks: How to config this ?

[evert_]

Good evening everybody,

I'm having since short a 5.1audio set, a logitech x540. I love this set, not too priced for a 5.1set. I'm coming from some crappy cheap trust 2.1set, so this is a big improvement.

But now the problem: my set needs to be connected to my motherboard with those '3 jack cables', because it's not having a coax cable. (normal for a budget set). But my motherboard has got only those 3 'normal' jacks. But not a big problem, i found the following in my motherboard guide:

Light Blue : Surround
Lime : Front Speaker Out
Pink : Center/bass

So hardware seen it isn't a problem to use those jacks . So i connected them like told in my motherboard manual. But now i don't get them working under linux. I don't know how to config it. I'm having the following audio card:
