I am trying to register for hardware changes. I found following link to do this: http://msdn.microsoft.com/en-us/library/windows/desktop/aa363432%28v=vs.85%29.aspx[^]

But, the hardware GUID described is for USB devices not for the Headphone port.

C++

// This GUID is for all USB serial host PnP drivers, but you can replace it 
// with any valid device class guid.
GUID WceusbshGUID = { 0x25dbce51, 0x6c8f, 0x4a72, 
                      0x8a,0x6d,0xb5,0x4c,0x2b,0x4f,0xc8,0x35 };

For following link I can get a lot of system defines classes but I am unable to sort out which one will be useful for Headphone detection:;

can any one help me?

Thanks

You are wrong. The USB GUID is brought here just as an example but you can replace it with any other valid GUID.

You don't want to be looking at all hardware devices, but rather device events for the Core Audio end-point devices. That can tell you when a headset is plugged in.
