Log Message:
-----------
Applied my own patch #1508018. I don't know for sure that it's exactly right,
but it improves the Adlib sound effects in early games, e.g. the door opening
and closing sounds in Indy 3 and MI1 floppy. There still appears to be some
kind of looping/repeating mechanism that we don't implement, though.
