Hi Ray, SoX is a basic cross-platform sound exchange program that works as a command line utility to convert between a wide variety of computer audio files. (At the sourceforge page it bills itself as "the Swiss Army knife of sound processing programs.") It can also play and record sounds. I've used this, ages ago (meaning more than 5 years ago) on other unix/linux platforms, and Greg Kearney recommended this as a player for the Mac back before this list moved to Google Groups.
I imagine that if there are interactions between this program that prevent all sounds from playing, including VoiceOver, that this is something that users like Doug Lee would like to run down (e.g., know whether it is specific to some interaction with Snow Leopard, or a problem in the current release of SoX). It would be pretty upsetting if all your sounds, including VoiceOver, stopped working. HTH.
