This event replaces the usage of the CallbackDeviceChange delegate and is only intended for usage with applications developed using Visual Basic 6 (which results unreliable when dealing with delegates and callbacks) and, in order to be enabled, requires a call to the COMEventEnable method with the nEventType parameter set to EVENT_TYPE_DEVICE_CHANGE.

 

This event is only intended for usage with Windows XP and earlier versions. When dealing with Windows Vista and higher versions it's recommended using the OnCoreAudioEvents event.
