Description Miklos Vajna 2013-08-12 07:22:06 UTC 
Problem description: 

Basic's Beep emits sound even if the sound mixer is muted.

Steps to reproduce:
1. Open e.g. Writer
2. Select Tools -> Macros -> Organize macris -> LibreOffice Basic
3. Select Main, and click Edit
4. Type "Beep" inside Sub Main
5. Mute system sound using the OS's mixer

Current behavior:

The beep is audible.

Expected behavior:

The beep should be silenced by the mute setting.

I don't think this ever worked, so not a regression.
Operating System: openSUSE
Version: 4.2.0.0.alpha0+ Master

Nothing to do with libreoffice really, that beep should route to either of these two beep impls...

//gtk
void GtkSalFrame::Beep()
{
    gdk_display_beep( getGdkDisplay() );
}

//generic
void SalDisplay::Beep() const
{
    XBell( pDisp_, 100 );
}

where presumably gtk just calls XBell as well, see if the following beeps for you as well...

#include <X11/Xlib.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main()
{
    Display *display;
    Window window;

    /* open connection with the server */
    display = XOpenDisplay(NULL);
    if (display == NULL)
    {
        fprintf(stderr, "Cannot open display\n");
        exit(1);
    }

    XBell(display, 100);

    /* close connection to server */
    XCloseDisplay(display);

    return 0;
}

Oh, indeed. Yes, the above beeps as well. And tweaking pulseaudio to capture XBell is possible:

So not a bug on our side.
