1. sound card emulate "built-in" speaker?
I recently got a cheap surplus laptop, & discovered that sound() doesn't
work on it. It occurred to me that I may have heard once that laptops don't
*have* the cheap "built-in" speaker that desktops do, which sound() would be
using, and has instead speaker(s) attached to a sound card. If that's true,
is there some way to "emulate" the sound() routine to work on the sound card
speakers? I need to *not* use .wav files, because the effect I want to
produce is a tone which varies continuously in frequency depending on a
variable input. (I might use .wav files in addition to the varying tone,
but I need the varying tone.)

Nevermind, nevermind, nevermind; the speaker was just turned off, and the
volume control that would have shown me that had been disappeared from
systray somehow, sigh.
I thought Topica swallowed my question, it can't even to the wrong thing
right!

If you're using a NT based system you can use the beep function that's
in the API.

Brian,
It's ok, I was wrong, the PC speaker *is* there, & *does* work; it was just
turned off, and the mixer icon somehow got removed from the systray, so I
didn't notice the PC speaker was just turned off :(
