windows – .Net WinForm System Beep on a 64 Bit OS – Stack Overflow

Posted by jpluimers on 2015/01/28

Thanks Shay Erlichmen for answering this on SO why the Beep function does not bell the speaker any more on x64 systems:

Beep has been removed as a native function from all x64 platforms (so no managed version of course), there is a connect issue that petition to return it.

We use a different trick to discover servers, we remote eject the dvd drive, and the drive with the tray open is the one were looking for :)

Larry Osterman has a great article about this: What’s up with the beep driver in Windows 7.

In the mean time, the connect issue has been removed as well.

The good news however (if your hardware still has an Intel 8254 compatible PIT in the South Bridge connected to a PC speaker):

Ludwig Ertl wrote the BEEPx / BeepXP driver that interfaces to the speaker through the 8254. Note it has a (German) changelog, but you can respond in English.
