Different Wav Files not working with OpenAL / PyAl

I found the following code on github that uses PyAL to create sounds that appear to move towards you by using the OpenAL library.

I downloaded all the files and went into the example folders to run the following audioplayer.py. It worked perfectly fine with the hey.wav file.

Now I wanted to run the exact same thing but with a different sound. So I got the following wav file and ran audioplayer.py. But the sound does not appear to be moving towards me and then away as it did for the hey.wav file. It just makes a constant sound over and over again.

I am confused why it works for one wav file and not for another?

"""OpenAL playback example."""
import os
import sys
import time
from openal.audio import SoundSink, SoundSource
from openal.loaders import load_wav_file

def run():
    if len (sys.argv) < 2:
        print ("Usage: %s wavefile" % os.path.basename(sys.argv[0]))
        print ("    Using an example wav file...")
        dirname = os.path.dirname(__file__)
        fname = os.path.join(dirname, "hey.wav")
    else:
        fname = sys.argv[1]


    sink = SoundSink()
    sink.activate()

    source = SoundSource(position=[10, 0, 0])
    source.looping = True

    data = load_wav_file(fname)
    source.queue(data)

    sink.play(source)
    while source.position[0] > - 10:
        source.position = [source.position[0] - 1,
                           source.position[1],
                           source.position[2]]
        sink.update()
        print("playing at %r" % source.position)
        time.sleep(2)
    print("done")


if __name__ == "__main__":
    sys.exit(run())

The audio file needs to be mono and not stereo
