This option was removed because it was unreliable and may or may not have worked depending on your Windows version and/or configuration. Support for it also seems to have been removed from newer versions of Windows. I have actually never been able to make it work on my notebooks, which run XP, and even on my old desktop, which is running Windows 7. Even support for the low level Beep() command, which was synchronous and froze the entire application while it played, seems to have been removed in recent versions of Windows.
