weird behaviour: pygame plays in shell but not in script

[Mik]

Dear all,

I am a bit frustrated by the following as I believe it is something
silly that I am not able to see.
I am using python 2.7.1+ under ubuntu.

When I run the following script as in
$python script.py
I do not get any sound out of it

BUT if I run every line in the python shell it works great.
It doesn't make sense to me, maybe someone has a clue?

Thanks for any clue!
Mik


import pygame

#done twice to get rid of a sound card error
pygame.mixer.init()
pygame.mixer.init()

pygame.mixer.pre_init(44100, -16, 2, 2048)

pygame.init()
# called twice to make it so that it detects sound card
pygame.init()

print "init"

sounds = []
sounds.append(pygame.mixer.Sound("../audio/song01.wav"))
sounds.append(pygame.mixer.Sound("../audio/song02.wav"))
sounds.append(pygame.mixer.Sound("../audio/song03.wav"))
sounds.append(pygame.mixer.Sound("../audio/song04.wav"))

for sound in sounds:
    print ".."
    sound.play()
