I just set up my new speakers ( logitech z - 5300 ) and im having some trouble calibrating them to 5.1. All speakers are producing sound. I have gone into my sound control panel and switched to 5.1 (both in windows and my sound card). The only two "different" channels that i am getting are left and right. The center and two rears and both blending into a right and left channel. So this leads me to believe i still have something somewhere set to 2.1. Oh if it helps i have a sound blaster audigy 2 zs sound card. Any help you guys could offer would be great. Thanks
