I just got a new sound card and well it has a dvd audio dvd with it and a dvd audio player. But its not working, it plays but no sounds comes out. I have the Sound blaster Audigy 2 ZS card with Klipsch promedia 5.1 digital souround sound. Everything else works but the dvd audio. Any ideas? this is the other wierd thing it does.. When doing a test like when the lady says "left front, center, right" only ones that work are left front and right front. But when i play dvd's or anything other than that, you can clearly tell the rears are on.
