Thank Jeff,
So am I really going about things the wrong way using CoreAudio as a
means by which to monitor any device? Or is it expected that I have
to have special case code to see if the particular device is
supported by CA and then use some other method?

Device aggregation only supports devices implemented via an IOAudio
family-based driver in the kernel. The reason why is that device
aggregation is exploiting features of IOAudio in order to function.
The iSight, being a user-space driver, is ineligible for aggregation.

I'm messing with aggregate devices at the moment, in my continuing
quest to be able to reliably monitor the audio level of some
random input device. In my case, I'm only wanting to monitor
things like mics, usb mics, and iSights - essentially any standard
input source.
I thought I'd then try the iSight, but soon found that when I add
a new aggregate in AMS - the iSight doesn't appear in the sub
device list.
What must I must do to get the iSight available as an input source?
