HyperCard, the application, doesn't use any of the new features of the
6.0.7 Sound Manager directly.  However, the Audio Help stack, which comes
with the new CPUs that support sound input, has an XCMD in it that does.
Anyone with a IIsi care to comment?

Yup, HyperCard 2.0 doesn't let you play sounds from the System file.  That's
because there's no way to know whether the sound you want to play is the
current beep sound -- and, in our testing, we found it was possible to make
nasty things happen if HyperCard was playing the current beep sound at the
same time that the system wanted to beep.  The only safe way to prevent
those nasty things from happening was to disallow the playing of sounds
from the System file.  Sorry.
