c# beep through system speaker - direct access to sys. speaker

I've used the following code and it expects to sound through the system speaker. The code really sounds but through the sound card (desktop speaker/headphone).

I think it will be possible to make some sound directly using system beep speaker since in device manager it displays the driver for that. Is there any work around for this.

** Not through default speaker / headphone. -- os win7 or 8 **

  Console.Beep(i, 100);

EDIT

It is confirmed that win7(at least 64bit or both and newer ver.) dose not use system speaker and instead they routes the call to default sound device. But my concern is,If the system speaker(hardware) is available and connected, isn't there any other way to access the device directly without using built in APIs to windows. I'd like to do some experiments on this(direct hardware access) and if you can at least provide me some starting point for this.

Windows 7 hardware requirements for 64 bit machines didn’t include support for an 8254 PIC chip, which is required for the internal PC speaker beep, so Microsoft changed how this functionality works for Windows 7 and the beep instruction is now re-routed to your Windows audio output instead.

So, it can't be done.
