AVbin Error When Loading Certain M4A Audio Files

Hello there!

I'm using pyglet to make a little handheld music player, and I've run into an AVbin issue when I try to load certain M4A media files using the pyglet.media.load function.

When I try to load certain M4A audio files I get this error.

C:\Users\Music Production\Desktop\Programing\Pathway Player Pre-Alpha\V1>python
error-maker.py
Traceback (most recent call last):
  File "error-maker.py", line 34, in <module>

The M4A files that cause this error seem to open fine on in other media players such as Media Player Classic for Windows or BeaTunes for Windows.

I have M4A files that load fine too, but I haven't been able to figure out the difference between the M4A files that load and the ones that cause this error.

Here is the code that I'm using to load these files,

#!/usr/bin/python3

def main():
    import pyglet
    import os
    import time
    from pyglet import clock

    window = pyglet.window.Window()

    @window.event
    def on_draw():
        window.clear()

    #----TRACK LIST CREATION FROM FOLDERS----
    #SETTING FOLDER LOCATIONS
    player_a_folder = 'C:/Users/Music Production/Desktop/Programing/Pathway Player Pre-Alpha/V1/player-a/'

    #PLAYER SETUP STUFF
    pyglet.options['audio'] = ('directsound', 'pulse', 'silent') #setting sound output correctly
    player_a = pyglet.media.Player() #creating a player

    #add absolue path to media file here:
    loaded_song = pyglet.media.load(r"C:/Users/Music Production/Desktop/Programing/Pathway Player Pre-Alpha/V1/player-a/creek.m4a")

    #adding loaded media file to the queue
    player_a.queue(loaded_song)

    player_a.play()

    pyglet.app.run() #LETS DOT HIS THANG! !!^O^!!

Here is a "pip list" of the python libraries I currently have installed

astroid (1.4.9)
colorama (0.3.7)
isort (4.2.5)
lazy-object-proxy (1.2.2)
mccabe (0.5.3)
pip (9.0.1)
pyglet (1.2.4)
pylint (1.6.4)
setuptools (28.8.0)
six (1.10.0)
wrapt (1.10.8)

I have also installed the most recent version of AVbin.

Here is a google drive link the examples M4A files that cause the error and ones that don't

M4As that load correctly: https://drive.google.com/drive/folders/0B4TzKg61IkDQVHBtWXNGeUk0X28?usp=sharing

M4as that cause errors: https://drive.google.com/drive/folders/0B4TzKg61IkDQblR2TVMyUFNwRE0?usp=sharing

Is there something about these files that is causing this error?

Let me know if there is any more information I can provide.

Thanks for making/maintaining this code, its been super useful!

Best Regards,
