Get/set the direction the audio source is pointing in the 3D cartesian coordinate space.
Depending on how direction the sound is, based on the `cone` attributes, a sound pointing away from the listener can be quiet or silent.
@param {string} sound_name - audio clip name - case sensitive
@param  {Number} x - the x-orientation of the audio source.
@param  {Number} y - the y-orientation of the audio source.
@param  {Number} z - the z-orientation of the audio source.
@param {number} [id] - the sound instance ID. If none is passed, all sounds in group will be changed.
@return {Array} the current 3D spatial orientation: [x, y, z]
