SB Audigy SE

Howdy!

I’m trying to get me SB Audigy SE to work. I’m only getting sound out of the front two speakers. I’ve got Logitech 5.1 surround speakers.

I’m at a loss. I’m using the IRC channel but no one’s around right now and I figured it couldn’t hurt to ask here as well.

Here’s some info:

Thanks!
