What implementation of Python are you going to use? I don't personally
know of any that can run on the "bare metal" without an OS.
I am planning to use python-on-a-chip(PyMite) which can be run without
an OS therefore I am looking for a module/library which can play sound
files.

As you wont be calling the OS via subprocess, which is about the only
way to fire up some connect to the sound system, you probably should be
talking about the pymite issues on the pymite group over at google about
drivers (i.e. sound drivers), what data types (wav, mp3, ogg) they will
take and how to pass data to a driver. The
nbed.AnalogOut looks intriguing. Perhaps you can spool a wav file to a port,
attach the
analog out to an external amplifier.

Also, perhaps you should be looking atArduino and audio projects.
