I just bulit my first pc. now i have installed the xfi card and is there some sort of audio wire that runs from my dvd drive to the new Xfi card?

Those havnt ben used since the win98 days I think... DVD audio is digital so that analogue cable is useless... Unless you have an older drive that has a play button on it to run sound straight from the drive to the soundcard, there is no need for it.

thanks for the info.
