Strange Problem with my x-fi fatal1ty

I recently got a new back-to-college desktop.

I added in a x-fi fatal1ty card myself and bought and hooked-up a set of z5500's to my system. For a while (2 days), everything was going great.

However, as anyone who owns anx-fi knows, there are a ton of software features that allow you to mess around with your sound.

Well, mess around I did. I didn't think I was doing anything too serious. However, after I have set everything back to where I thought they were before (restoring defults and restoring my minor adjustments to when the sound was satisfying), my music still sounds washy and unsatisfying.

Moreover, when I run the speaker diagnositcs, only 2 of my 5 speakers "report": the front left and rear right. Before, it was only my front right that missed out, but because everything sounded great, I didn't bother trying to figure it out.

Does anyone have any idea whats going on?

I appreciate it.
