My xfi xtreme gamer fatality card is not recognized

[ruthless_riot]

i recently purchased an xfi xtreme gamer fatality sound card. me and my roommate have spent about two days trying to figure out why it wont work. it started out that the card would not even be recognized, after repeated attempts we finally got it to install but it still is giving off no sound. we first tried looking to find out what the error code (code 10) meant but we could not find anything im not as good with computers as my roommate but im sick of the hastle,so any help would be great note: the whole setup was bought less than a week ago and the sound card seems to be the only problem
