Sounds played via Matinee do not respect Pause and Play of Matinee

When you place a substantially long Sound Cue/Wave in an Empty Group of a Matinee and set the Matinee to play on level load then on a key press pause the matinee and play the matinee, the sound group ignores the pause and play functions.

? - >This may be a limitation of the sound system in the engine currently.
