Hello,

In the game a lot of noises will be non-existent (my car, gunshots, some environmental noises) while others (other cars, other environemntal noises and music) will be just fine. This is when I select 5.1 Surround with Hardware Mixing. With Software Mixing or with quad speaker setup the sound is fine. EAX makes no difference one way or the other.
Quad sound is OK except that I have to go into the sound properties after I play the game and reset my computer to 5.1 again (PITA). Is there a work around or a known issue here?

Any help will be apprecited.

I didn't find the right solution from the Internet.
