the docs say that you can
only have  one output unit in a graph.

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:
No, you don't have to do that. You can create a graph, open it, add nodes and the right thing will happen. You can add nodes to a graph at any time (including even a running graph).

-NewAUGraph()
-insert the nodes with their appropriate component descriptions
-connect the nodes
You don't have to do this here either - you can connect nodes at any time.

If you want to see this in action, have a look at the AU Lab application and in the Debug menu print the session out.

-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.
