Can anyone tell me what error -12986 is coming from my AUGraphConnectNodeInput call?
I can't find it documented anywhere yet. Only happens on iPod Touches.
TIA.

This error is getting propagated up from a routing layer beneath AudioSession. It seems to indicate:

	- the session's category requires audio input
	- there is currently no audio input device present

Should these conditions both be true?

I'm a bit surprised that AUGraphConnectNodeInput would trigger this chain of events. What are you connecting to what? Is the graph running?
