[yaniv]

hi 
i have a program that need to make sounds . i use the pygame library ,
using a code i have taken from chimp example .
it works o.k. except the first time i run it throught idle , when
there's no sound . i end the program , run it again , and everything
is fine .

what do you think causes this ?

    import os,pygame                       # http://www.pygame.org/


def load_sound(name):
    class NoneSound:
        def play(self): pass
    if not pygame.mixer or not pygame.mixer.get_init():
        return NoneSound()
    fullname = os.path.join('', name)
    try:
        sound = pygame.mixer.Sound(fullname)
    except pygame.error, message:
        print 'Cannot load sound:', fullname
        raise SystemExit, message
