python - Pygame, sounds don't play

Question

I'm trying to play sound files (.wav) with pygame but when I start it I never hear anything.
This is the code:

import pygame

pygame.init()
pygame.mixer.init()
sounda= pygame.mixer.Sound("desert_rustle.wav")

sounda.play()

I also tried using channels but the result is the same

Answer 1

For me (on Windows 7, Python 2.7, PyGame 1.9) I actually have to remove the pygame.init() call to make it work or if the pygame.init() stays to create at least a screen in pygame.

My example:

import time, sys
from pygame import mixer

# pygame.init()
mixer.init()

sound = mixer.Sound(sys.argv[1])
sound.play()

time.sleep(5)
