I've *never* had this problem with my M-Audio Audiophile, and I have loud good speakers and headphones so I'm sure I would have heard it. (Semi-pro) PCI-soundcards generally are free from intercepting electrical noise. Otherwise you'd have to close down most sound studios and our radio station: there are PCI cards all over, but not a single USB card in sight. Of course one thing that's strictly forbidden would be to run a cable from the CD/DVD drive to the soundcard as this acts as an antenna to pick up noise. But only "consumer cards" even have a connector for this junk, most internal semi-pro soundcards starting at around 70 Euro like the Terratec Phase22, M-Audio Audiophile, ESI etc. don't and they are shielded well enough to not pick up noise. Onboard cards are a different story: For laptops I've yet to find a machine that wouldn't need an external USB/FW-box.
