When I run "playmidi -a score.midi", it
looks like it's
playing, but there isn't any sound. (Yes, the speaker is plugged into
the right place.) I've looked at the mixer settings
and don't see anything obvious to change.
Did you load a soundfont with sfxload?
(You could use the 8gmgsmt.sf2 (i think) soundfont that comes on the SBLive
driver cd)
