If you failed, there is always the concept of the "analog hole". The digital audio has to be converted to analog at some point, so you could do something absurd like running a cable from your speaker jack into your microphone jack, and use the windows sound recorder, or anything that can record from microphone (including a tape deck). Also, audacity will do it, so will Adobe Audition, and basically any other sound recording software can record streaming sound or anything you hear from computer.
