Can't get Audigy 2zs to work

[Tom|Nbk]

just recieved my Audigy 2 ZS fully uninstalled my on board drivers and grabbed the latest ZS drivers thought it would be a walk in the park, boy i was wrong ive set my analouge speakers into the soundcard properly i do not have my breakbox setup yet but surely the soundcard should work fine without it, all im getting is distorted sound what can i do about it this is highly annoying now.

For some reason the soundcard will work fine until i plug in the Black rear speaker jack then it all goes to pot and the sound is totally garbled and distorted whats wrong with it .
