Subs on and off? Can do that... Int on and off? Can do that (Shame about the random problems)

Although the weird mask problems are carry on and there is some random stopping in the last scene, I've got the subs on and off working, the int on and off working, and know how to do the sound on and off, after that I've done all the stuff I can do alone (to be honest by then I won't have much left to do :D)
