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.
About eight months ago, I picked up a Dell Latitude C400 from thrift shop, planning to put some sort of Linux on it. The laptop booted, but I got the gray screen of death (later diagnosed as a hard drive lock).
