Not sure why your .mp3 file is named *.mpg, but that doesn't
matter (though .mpg and .mpeg are typically used for a/v files).
My typo - sorry.
Ensure the permissions on the sound device files are correct,
I've got /dev/sequencer{2} and /dev/snd/{seq,timer}, all crw-rw---- and
I'm in the audio group - does that sound about right?
and use the 'aplay' command to play a .wav file. Even more
basic is to use the 'speaker-test' program.
Once you can get aplay to play the .wav file, everything is
downhill from there.
Ok - so my strategy now could be to try to get speaker-test working, as
it's even more basic than aplay? Sadly:
~$ speaker-test
speaker-test 1.0.11

I'm guessing this means there is a kernel configuration or driver problem?
If that's completely off-beam, please let me know!
Thanks for your (and the others who replied) quick & helpful response(s).
