Audion breaks Box2DJS demo

With Audion enabled, navigate to the Box-2D demo. The demo fails with the following console message:

prototype-1.6.0.2.js:209 Uncaught TypeError: Failed to construct 'AudioContext': Please use the 'new' operator, this DOM object constructor cannot be called as a function.
