Have you tried Pyglet 1.2 alpha1 or the repository code?:
Both, although i'm currently running & testing with 1.2a1.

What steps will reproduce the problem?
1. Initialize a sound in pyglet and play it (either through a player object or 
directly with play())
2. Wait between 24-54 seconds.
3. Experience how the audio output suddenly stops.

I've added some minimal code at the bottom that isolates the problem.

Any additional info (platform/language/hardware) that may be relevant?:

Tried it on 2 different machines running OSX 10.9 (Mavericks) - a  late 2011 
MBP and a late 2013 MBA, both encountered the same problem. I have not had the 
possibility to try other platforms so far.
I've tried various file formats (ranging from simple 16bit mono wavs to stereo 
24 MP3's etc) and I also tried running different versions of Avbin (2 different 
releases of version 8 and version 10) without any luck.

Here is some pretty minimal code that I wrote to isolate the problem:
----------------------------------------------
"""
test.py
"""
import pyglet,os
os.chdir(os.path.dirname(os.path.abspath(__file__)[0:-6]))


pyglet.options['debug_media'] = True

player = pyglet.media.Player()
player.eos_action = player.EOS_LOOP

I can't recreate this error on linux mint 15 python 2.7.4 and pyglet from the 
repository.

I'm finding the exact same thing on Mac OS 10.8.5 and pyglet 1.2α

symptom: music stops after about 25 seconds of playback
steps to reproduce: run the code below with any mp3 file

#!/usr/bin/env python
import pyglet;

pyglet.options['debug_media']=True;

window = pyglet.window.Window();
player = pyglet.media.Player();
music = pyglet.media.load('~/Desktop/example.mp3');
player.queue(music);
player.play();

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

window.push_handlers(pyglet.window.event.WindowEventLogger())

pyglet.app.run();

Same issue with Pyglet 1.2x and OSX 10.9.4. Music plays for around 30 seconds 
or so then cuts off. 

    song = pyglet.media.load('example.mp3, streaming=False)
    song.play()

The streaming flag doesn't make a difference.


Here is the the output from the media debug log
