We need to get notifications of when the default device changes. We do this through a device enumerator by
registering a IMMNotificationClient with it. We only care about this if it's the default device.
We need to register a notification client to detect when the device has been disabled, unplugged or re-routed (when the default device changes). When
we are connecting to the default device we want to do automatic stream routing when the device is disabled or unplugged. Otherwise we want to just
stop the device outright and let the application handle it.
