RegisterDeviceNotification for KSCATEGORY_AUDIO_DEVICE

[JoderCoder]

It says KSCATEGORY_AUDIO_DEVICE class is reserved, but is there a problem for registering for device notifications via RegisterDeviceNotification?

I've also seen "Note that the SysAudio system driver reserves the registry category KSCATEGORY_AUDIO_DEVICE exclusively for its virtual audio devices. Adapter drivers should not register themselves in this category."

Should I understand this in a way that I cant even register for device notifications either?

Thanks for any input!
