Thanks for the help on this one. It was correctly pointed-out to me
that these symtoms are caused by not having the Sound Manager
extension installed (the Macs that worked were running System 7.5
which has this built-in). The Sound Manager extension can be obtained
through Apple's WWW server at http://www.info.apple.com/apple.web.page1.html.
Everything works fine now!
