The sound produced by sound() is supposed to come out of your system's
beeper.  If the system doesn't have such a thing, and/or the drivers
don't support DOS, or you've silenced the beeper in your sound
hardware's volume control panel, then you won't hear anything.  4000
Hz is also rather high --- it's uncertain the beeper supports it.

This much simplified programs works just fine on my laptop:

#include <pc.h>
#include <dos.h>

int main() {
    sound(1000);
    delay(1000);
    nosound();
    return 0;
}
