yea, and you are only using one device (both for input and output). In your code, some steps in
setting up the graph are in the wrong order (in your monitor.. method).
you should add the set of nodes  to the graph and make the appropraite connections, before
opening the graph. so the order should be:
-NewAUGraph()
-insert the nodes with their appropriate component descriptions
-connect the nodes
-AUGraphOpen()
-obtain the references to the AU's that have just been instantiated by calling augraphopen()
-enable metering
-enable I/O on the input scope / element 1 of your device
-AUGraphInitialize()
-AUGraphStart

I've just tested this with the built-in audio and it works fine.
