There is no sound or music on my game unless I put it to either, pro logic or stereo...is this a known issue?

We're currently looking into this issue. If possible, can you unplug the two side speakers, set Windows to use 5.1 and see if the game is able to play with sounds up to 5.1?

We're trying to collect more information on this issue. Can you guys that are not getting sound with the 7.1 setup reply back with the following information?

-Sound Card:
-Operating System:
-Speaker system model:
-Any miscellaneous configuration information you may think is useful:
