I have a SBLive LS 5.1 card, and a friend of mine referred me to the kx project drivers when my system became unstable due to the Creative drivers (Windows wouldn't get past the bootup splash screen 9 times out of 10). For the most part, they work well. Unfortunately two of my games have problems with sound now. With EAX enabled in Halo PC, there is no music and some sounds don't play in the cutscenes. When I enable EAX in Splinter Cell Chaos Theory, there is no noticeable difference from ordinary sound with no hardware acceleration. Both of these games worked as expected when I had the Creative drivers installed, but there was never any guarantee that I would be able to get back to Windows if I ever had to reboot.
