Pygame throws no errors but doesn't play any audio

Question

I am trying to use Pygame to play an .mp3 or .wav file. I want to do this on my Raspberry Pi 4 running Raspbian Buster, although the same test has been made on Windows and the same results occur:

import pygame

pygame.init()
pygame.mixer.init()


audioFiles = [r'C:\pythonAudio\romeo&juliet.wav']

pygame.mixer.music.load(audioFiles[0])
pygame.mixer.music.play(0)

No errors are thown when I run this and the following is output to the console:

pygame 1.9.6
Hello from the pygame community. https://www.pygame.org/contribute.html
[Finished in 1.372s]

Am I missing something obvious? I have been using SimpleAudio as an alternative which works but is only compatible with .wav files as opposed to .mp3.

Answer 1

The program ends as the music is being played in a different thread. In other words, pygame.mixer.music.play(0) will not wait for your song to finish but instead play it simultaneously with your program. Try:

import pygame

pygame.init()
pygame.mixer.init()


audioFiles = [r'C:\pythonAudio\romeo&juliet.wav']

pygame.mixer.music.load(audioFiles[0])
pygame.mixer.music.play(0)

while pygame.mixer.music.get_busy():
    pygame.event.pump()

This will keep your program running until the mixer is no longer busy (no longer playing any music).

Answer 2

Try converting it to an Ogg. Support for the other audio formats tends to be a bit inconsistent with Pygame.
