Hey guys i just bought some Logitech Z-5300e 5.1 surround sound speakers for my computer. So i hook them up, everything seems nice. I load up itunes and play some songs, the speakers sound terrific. I go to play CS Source, and nothing works. I try other games like BF2, Guild Wars, and some other games... they all work. I try Half Life 2 and DOD Source and the sound doesn't work in those games either, so i know it's the Source engine games that i'm having trouble with. It's very weird, the sound works in the little intro where it has the guy with that red thing in his eye, then when the game loads up, there's no sound at all. I have a Soundblaster Live sound card just to let you know. OH, and the sound works on the original Counter Strike. If anybody knows how to fix this problem, please let me know. Thanks.
