I recently hooked up a set of 5.1 speakers to my Santa Cruz. My problem is that when I play games with EAX turned on, there's no sound coming from the center channel. In games like Max Payne 2 and Call of Duty, I can't hear gunshots that I have fired myself and some cutscene dialog. I read on Activision's website that there are issues with some sound cards not being able to produce center channel sound in 5.1 mode, but I'm curious as to what my options are concerning this.
