I know a couple of you out there have this, Zorro and I think Leo. I am having a minor problem that is driving me crazy. After I play Tribes 2 my game theater settings are always reverted to two speakers instead of four. You guys ever have this problem also? I think I have already tried changing the speaker settings inside tribes to match the 4 speakers, and I don't think that worked. Maybe I should see if there are any newer drivers or something.
