I'm not an expert by any means. What sort of pickups does the guitar have,
and is the noise you are experiencing similar to mains hum you might hear
through an amp?

It could just be that the signal from the guitar is too low, or generally
noisy and the digital gain on the card just magnifies the noise. I have a
Terratec DMX 6Fire (has a built-in pre-amp) and have to turn up the pre-amp
quite a way to get a useable signal.

Maybe you could use an external pre-amp and/or noise gate effects pedal before
the signal goes into the card?
