I did almost all my testing in irb - where that set of lines worked
perfectly, but when I tried to write a simple jukebox I ran into the same
problem you did.
There is some timing issue - the player is running in a separate thread or
process, and it doesn't respond instantly to the ole calls.  The quick
solution I came up with was to add some sleeps between the calls.  There's
probably a better solution involving checking statuses.


w =3D SimpleWinMediaPlayer.new
w.volume =3D volume
songlist.each {|song|
  puts (fullname =3D 'file://'+dirname+'/'+song)
  w.file=3D fullname
  sleep 0.1
  w.play
  sleep 0.1
  puts w.duration
  sleep (w.duration)
  while w.current_pos !=3D ""
      sleep (0.5)
  end
}
