Clicking 'Sound Settings' in Lubuntu is a no-op

[Juerg Haefliger]

Nothing happens when clicking 'Sound Settings...' in the indicator applet on a fresh install of Lubuntu 17.04.

This is probably because of the following code in src/sound-service-dbus.c:

static void
show_sound_settings_dialog (DbusmenuMenuitem *mi,
                            gpointer user_data)
{
  GError * error = NULL;
  if (!g_spawn_command_line_async("gnome-volume-control --page=applications", &error) &&
      !g_spawn_command_line_async("gnome-control-center sound", &error) &&
      !g_spawn_command_line_async("xfce4-mixer", &error))
  {
    g_warning("Unable to show dialog: %s", error->message);
    g_error_free(error);
  }
}

and the fact that none of the above is installed (or available) by default.

I 'fixed' the issue by creating a symbolic link xfce4-mixer -> pavucontrol. Maybe pavucontrol should be tried in the above code as well since that seems to be the default in Lubuntu?
