The more complete test case still doesn't sound a bell on my system
with a local connection on b127:
$ cat test.c
#include <stdlib.h>
#include <stdio.h>
#include <X11/Xlib.h>
int
main(int argc, char *argv[], char *envp[])
{
Display *dpy;
int rv;
if ((dpy = XOpenDisplay(NULL)) == NULL) {
perror("Opening display");
return (1);
}
(void)XBell(dpy, 100);
XFlush(dpy);
XCloseDisplay(dpy);
return (0);
}
$ cc test.c -lX11
$ ./a.out
$
