 So, I used to use the -dumpaudio switch in mplayer to get audio extracted from random videos, but now that seems to do not much of anything.  I found this site which had a great explanation of how to get it done a different way, but was a bit out of date.  The newer version is found below:

mplayer -vo null -ao pcm:file=audio_file_name.wav video_file_name.avi

Hope that helps you as much as it did me.
