Here's the relevant part of a script I've been using to do this. It's

nothing fancy but it works, it just dumps the audio as numbered wav

files (one file for each chapter). With a bit more creative scripting

you could automatically set the variables at the start by pulling them

out of lsdvd's output, but I'll leave that as an exercise for the

curious reader (i.e. I am lazy).
#!/bin/bash
#set these to match the dvd you want to rip

#use lsdvd to figure out which title and how many chapters you need

dvdpath=/dev/sr0

title=1

number_of_chapters=18
songnumber=1

while [ $songnumber -le $number_of_chapters ]; do

    mplayer dvd://$title -chapter $songnumber-$songnumber -dvd-device

$dvdpath -vo null -vc dummy -ao pcm:file=$songnumber.wav

    let songnumber=songnumber+1;

done
