have a dell optiplex gx280, a samson CO3 condenser mic, a behringer tube ultragain mic200 pre amp and for sound, i just have the whole thing hooked up to a kenwood mini hifi component system.

my problem is this..

i just bought a new soundcard, a sound blaster audigy 2 6.1 24bit digital, BUT, it crackles all the time. more so when i adjust computer volume levels thru its mixer(on the computer). i have properly configured everything and i dont understand why this crackle wont go away. when i attempt to record with cool edit pro, it just makes funny patterns in the .wav table like it has a digital encoding problem or something.im starting to think i have a faulty sound card. i have up to date drivers for the soundcard n all, the latest version of directX, and the ******* of a thing still wont work.

any help would be greatly appreciated.

P.S - the soundcard doesnt look damaged in any shape or form.
