This is probably an old question so please humor me. Before my application
starts, I need to check the user's system for fonts, monitor rez, and sound.
I'm already using "mFont" to handle the font questions and I think I've got the
monitor problem handled, but I'm having trouble with sound detection. 

What I'd like to be able to do is:
1) Check their system for sound capability
2) If they are sound ready continue with the app.
3) If they have no sound capability, turn off all the sounds in the app
(buttons,    sound icons, etc.) so the user does not receive any error
messages.

Thank in advance,
Bill
