Using the Sound Manager in MacIvory

    According to Inside Macintosh Vol. 5, the corresponding toolbox
    routines, SndPlay and SndNewChannel, should work if you pass NIL as the
    first argument; i.e. the toolbox will generate a channel for you if you
    don't have one in hand to pass as the first argument.  Without this
    capability I don't see how to gat a channel to begin with.

This NIL is a 32-bit 0, not your friend from LISP.

The MTB:_ entries do not convert.

The RPC code is rather reluctant to type check its arguments in the name
of efficiency.  It sent over a few random bits from the pointer field of
the NIL LISP object.
