Does it just not play? Any other information so I can work to fix it. What system are you running it on?
Seems to work for me, BUUUUT the console is giving out tons of errors, for example:
AttributeError: 'NoneType' object has no attribute 'pause'
[ERROR] KX_PythonComponent[Player] - Failed to invoke the update callback.
Soundfile F:\SFX\Steps\step_1.mp3 could not be loaded!
Soundfile F:\SFX\Steps\step_1.mp3 could not be loaded!
Soundfile F:\SFX\Steps\step_1.mp3 could not be loaded!
So far, the game IS running (though just windowed) but the sound is completely missing.
