There is a program called dvbaudio which is part of dvb-mpegtools (
http://www.metzlerbros.org/dvb/index.html). You can either use it to
get the audio elementary stream and pipe it into mpg123 or similar
programs. Or you can have a look at the source and use it to write a program
that uses an mpeg codec from some lib and does this in one step. 
I was not going to do that, because I don't want any more library
dependences in the dvb-mpegtools. They are supposed to be standalone.
