Right, I know have a different problem, but it can be demonstrated
with a modified version of the same test.
from itertools import cycle
from pyglet import window, app, options, clock
options['audio'] = ["alsa", "openal"]
from pyglet.media import Player, load
class SoundTest(Player):
def __init__(self, tracks):
super(SoundTest, self).__init__()
self.iter = cycle(tracks)
self.queue_next()
self.queue_next()
def queue_next(self):
self.queue(load(self.iter.next()))
def on_music_skip(self):
self.next()
self.queue_next()
def on_eos(self):
self.queue_next()
WINDOW = window.Window(640, 480, "Sound Test")
PLAYER = SoundTest(("sounds/music/menu/defense theme.ogg", "sounds/
music/menu/ronima.ogg"))
PLAYER.play()
clock.schedule_once(lambda dt: PLAYER.on_music_skip(), 10)
app.run()
Once the track is skipped to the next one, it all goes wrong:
