pygame.mixer.music.queue not working for me!

I'm sure I'm missing something simple, but I just can't get the queue function to work. I'm using Python 3.4.2 under the latest Jessie release on a Pi 3. I have tested with wav and ogg files.
Code: Select all
PATHAUDIO = '/home/pi/Music/'
ext = '.ogg'
print(ext)
pygame.mixer.init()
pygame.mixer.music.load(PATHAUDIO + 'first' + ext)
pygame.mixer.music.play(2)
pygame.mixer.music.queue(PATHAUDIO + 'second' + ext)
#pygame.mixer.music.play()
print('done')

The first audio file gets played three times, but the second one is never played.

Can you verify that the second file plays through pygame?

Also, how are you running this code? If you execute it as a python script then, without some loop at the end, the code will just exit.

I don't have a pi that I can easily test this on. However, I've tested it on my laptop (Ubuntu) and it works as expected for me.

This was the code I ran:
Code: Select all
import pygame
import time

mix = pygame.mixer  # This is just me being lazy!
music = mix.music  # ditto

f1 = "/usr/share/sounds/alsa/Front_Center.wav"
f2 = "/usr/share/sounds/alsa/Front_Left.wav"

mix.init()
music.load(f1)
music.play(2)
music.queue(f2)
print "Done"

time.sleep(15)

Yes it does.

I thought the same thing and had already tried adding sleep(20), but same result.

It appears the problem is pi specific as the code works on your laptop.

If pygame.mixer.music.queue does not work, can anyone suggest an alternative python library that has the ability to queue music in a non blocking fashion?
