Hi All;

    Even though functions sound(), nosound() and delay() are listed
    as valid gcc built-in function in:

    http://www.delorie.com/djgpp/doc/libc/

    they don't seem to work on my computer (HP a810n, AMD-64,
    Realtek AC'97 Audio).  For example, the sample code below
    compiles like a charm but produces no sound or delay at all:

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

int beepz(int freq);

int main(void)
{
    int a;

    a = beepz(4000);
    return(0);
}

int beepz(int freq)
{
    printf("\n Beepz \n");
    sound(freq);
    delay(180000);
    nosound();
    return (0);
}

    I then ask, what's wrong here?  Thanks in advance!
