Hi Jeff,
Thanks for the info. Actually, I'd prefer that there be an external
app (gui) to make that setting ... it doesn't belong in my code. But
I have no idea where the "Sound Prefs panel" is under OS-X. I don't
see any sort of control panel type thing in OS-X 10.1 (I know that
there is such in OS 9). I was told by Apple support that there would
be such a thing in OS X 10.2, but I just bought this computer
(delivered in early July) and I don't have the cash to fork out for an
upgrade that I think should have come with the machine (especially for
a developer!).
