XBOX 360 with SBS 580

[yourdogsmom]

In the future i will be using HD to VGA cable which i already have to connect my xbox 360 to my pc!
I also have some Creative SBS 580 5.1 surround speakers but the thing is the HD to VGA cable has a white and red cable for the sound but my speakers have a green, orange and black cable so i cant connect them, therefore i will have no sound!
So what can i use to connect them together and not lose the surround sound?

Have you tried putting the red and white cables in the ones you have on your speakers?

There arent any red/white on my speakers - only an audio input cable coming from the back of the speakers which is fixed and has a green, orange and black cable!
