mad installed & oggs work but..

[Jeff Hodges]

So, I installed Ubuntu on my lil bro's computer and noting that he
really likes to listen to music, I made sure that gstreamer0.8-mad was
installed on his system.  All fine and good except that mp3s won't
play on his system /even through mpg123/.

Oggs work fine, so do the gaim and startup wavs, but no mp3s.  I'm
thoroughly confused.  His system loads up the snd_ac97_codec,
snd_ens1371 and snd_rawmidi  modules but I don't know how these could
be the culprit.  Anyone have a clue?
