That's interesting, because that's the opposite of the usual desire!

How DO you want to be able to use your device?  If you do not register
yourself as an audio device, you will not be in the DirectShow list. 
But if you hope to find the device in your own application using the
system device enumerator, then you have conflicting goals.
