We've had a bug report that the GUIDs reported with DirectX enumeration for our devices change after the user changes the prefered audio device but that others in the system remain constant. Does anyone know what triggers the regeneration of the reported GUIDs for some devices? Is there some change we could make to keep the GUIDs reported for our devices constant?
