I have noticed the same thing...it is caused by a 'ground loop' between the sound card and the and the synth. The PCIF cable ground and the audio ground are not quite the same. I have 'fixed' the problem in my system by ensuring that the PC and the synth are plugged into the same power stip, AND running a separate ground wire between the synth and the soundcard. Incidentally, I do not have the problem when I send the audio to a separate mixer . Cheers!
