SPU2-X: TDA is a fake internal register (which should probably be nuked), so reading from the FIFO (or whatever 1AC is) certainly shouldn't use it. Also fixed up related code a little. We don't know of any games which actually use this though. Actually I don't know if we know that reading this register does anything, this could all be the product of an overactive imagination.
