Audio file not playing Python Pyglet

Question

I am trying to play a audio file using pyglet but I get the error below. Why is this and how can I fix it?

Code:

import pyglet

player = pyglet.media.Player()
sound = pyglet.media.load("air_raid.wav", streaming=False)
player.queue(sound)
player.play()

Error:

Traceback (most recent call last):

The same code works on my laptop with Python 2.7. I guess there maybe something wrong with your .wav sound file. Please check whether your sound file is empty. I downloaded sample14.wav from http://download.wavetlan.com/SVV/Media/HTTP/http-wav.htm and it really works. Could you test the same sample14.wav file?

Another possible reason may be the the version of your pyglet not matching your python version.
