I just tested a few with this snippet and they ran fine.
sync on : sync rate 60
load music "alive.mid",1 : loop music 1
disable escapekey : while escapekey()=0
sync : endwhile
delete music 1
end
does the midi play in quicktime or another audio playing program?
re install your sound card drivers if it doesnt.
DB might not like that midi file so inspect the midi file in case theres something obvious DB doesnt like.
