Sound for linux

Im fed up with trying to get drivers working with my turtle Beach Santa Cruz card. I just installed ALSA and it works with my card but only for the front speakers. Unless someone here knows how to make my card work with surround sound, im gona get a new card.

I need it to surrport surround sound and linux(it would be nice if the drivers came from them officaly like from nvidia cards).

Thanks
