Sort of talking based on experience and a little knowledge here.

I am betting it is still present.  If so, it's probably just garden
variety RFI.  There would be two things that could cause this:
interferance on the card itself, and interferance that comes with the
external cabling.  That's usually the one that gets me.  If you had a
sound card before and it didn't make the same sounds it's probalby not
cabling.  :-)

One thing that can make noise worse is low output volume on the
soundcard.  If the output is not very loud, a constant noise will
contribute a lot more to S/N.

Or it could be something totally unrelated.
