[[DAS REICH] Blitz]

I'm trying to make a YTMND using a video I found on youtube, but I can't record the sound off the video using Audacity. When I learned that I needed to enable my recording options via my sound controller, I noticed I only had three options (Internal Mic, External Mic, and Line-Out). I couldn't find the "wave out" or "stereo mix" options needed to make a good sound file. I have a SigmaTel sound card, does anyone else have this problem?
