If the audio is mp3 to begin with, just use

mplayer -dumpaudio source.avi

Otherwise, you'll have to use

mplayer -ao pcm -vo null -vc null source.avi

to write the audio to a wav file. This takes a lot longer but it will
work for any source audio type mplayer can play.


P.S. Please send replies to the list, it makes thing a lot easier.
