We just got a new dell media center PC with the Audigy 2ZS sound card. After reading the specs for the audigy cards I found out that only the platinum pro version decodes DD-EX and DTS-ES soundtracks. The platinum pro seems like overkill with the external IO switcher and whatnot. Is there any way I can play 6.1 soundtracks without upgrading the card? If not, why did I bother getting the 6.1 speakers... thanks in advance
