SB 5.1 and Counterstrike

In the game, my headphones work rather well now (a lot better sound, than the onboard audio from mb specs below) I bought the SB live 5.1 card, but still cant get the mic to work in the game. I have cable connection and the onboard LAN works rather well so I dont have anything but it plugged into the PCI slots except new sound card. I plugged the live 5.1 into the 2nd up from the bottom (slot) and not the one next to the AGP slot. Has anyone run into (and solved) a problem like this? I have checked the windows settings (mic is active and works in the voice test), disabled the onboard audio in the bios, and I have tried running the "voice_tweak" in CS, it gives me an error of "cant load voice_codec in ***.dll" or something like that. Please help.

Thanks,

Bill
