So I got in touch with Christos today and he's uploaded our sound manager to the main branch of the tetris game.  I took a good look and it all seems to hold up well. We tested it internally with a couple of button presses and I'm happy with how it turned out. I posted to the class forum to announce to the other teams that our code is ready to be used. I hope it's all straight forward and the other teams can use it intuitively. I added in a few comments, although it looks rpetty obvuious as to how to use the code correctly. Hopefully more of the code from other teams can be seen soon.  Looks like we're finished.
