If you want to rip an audio track from a dvd you should use dvd syntax:

mplayer dvd://i -aid 128 -dumpaudio -dumpfile sound.ac3
eventually with -chapter n-m if you want to limit the output.

For more fine control you can use mencoder.
mencoder dvd://i -oac copy -of rawaudio -ovc copy -o sound.ac3 -aid 128

Thanks Giacomo.  I am not sure why, but all I ended up doing was changing the name of the file to write to and it worked just fine.  I also changed to the "dvd://" instead of the vob_filename.VOB.
