Thank you for replying syphus.
You are a good help.

Here is the exact model of my speakers.

From what you're saying, it looks like I need 3 stereo cables that goes from auriga to my audigy 2 in order for a 5.1 surround sound to work.

Looks like I will need to go out and buy an adapter cable. Thanks so much!
