/** Plays the audio data from the given file
* \param fileHandle PhysicsFS file handle to stream the audio from

* \param onFinished callback to invoke when we're finished playing
* \param user_data user-data pointer to pass to the \c onFinished callback
* \return a pointer to the currently playing stream when playing started
* successfully, NULL otherwise.
* \post When a non-NULL pointer is returned the audio stream system will
* close the PhysicsFS file handle. Otherwise (when false is returned)

* \note The returned pointer will become invalid/dangling immediately after
* the \c onFinished callback is invoked.
* \note You must _never_ manually free() the memory used by the returned
