Noise and Audigy 2 ZS

what the ####…

mm just got the card to record 24/96 with the creative drivers, everything works like a charm… except… on n-track (and other multitracks programs) i get noise levels of -40 even if nothing is plug in to the line in jack i mean, i use to have soundblaster Live (not the 24bit ver) and this wa never a problem, i mean it’s not that big of a problem… you can always clean the audio track with a program or something… but #### is annoying as ####, anyone knows how to get rid of this??? i would be forever greatfull to anyone that helps me ???
