Here's the problem:
Whenever I play a game that uses EAX, there are certain sounds I can't hear. Like in FEAR, I can't hear the music or radio transmissions, and in COD2 I can't hear music or weapons sounds. When I switch to the Miles 2D Sound thing, I can hear everything fine, but it's not 5.1 and there's no EAX. On FEAR, there are no options to alleviate the situation.
This is STILL happening after a new soundcard AND a full system reformat. What the **** could be the problem?
