The right cable is a mini-stereo to mini-stereo cable. EDIT: Leroy's response below is better; I had a brain-freeze.
If one has a Creative (What U Hear) or Realtek (Stereo Mix) sound card then one does not even need a cable. Couple a cable/no-cable setup with Audacity and you're set.
Thanks for the suggestions. I've done all the things you've suggested, Guru, to no avail. I'm gonna take it up to my girlfriend's house tomorrow and use her machine for testing purposes while she's at work. I'll let ya know how it turns out.
