The HAL stores the aggregate device descriptions in in /Library/
Preferences/.GlobalPreferences.plist. There are two parts to it.
First, under the key,
"com.apple.audio.CoreAudio.AggregateDeviceUIDList", is the array of
UIDs for all the aggregate devices. Then, there is a key describing
each aggregate device in the form "com.apple.audio.AggregateDevice.*",
where the * is the device's UID.
You would need to delete both the UID list and all the individual
descriptions to clear out the aggregate devices.
That said, if you can can make that happen, please file a bug so we
can fix it.

Probably a question for Apple.
We have a machine here that we use for test and support and one of the
things that we do with it is create and destroy Aggregate devices
using AMS.
Just today, things have gone south on this machine. If we create an
aggregate device in AMS, it shows up in the Aggregate device editor,
but it
does not appear in the list of available devices in AMS or in any
other
CoreAudio app.
It appears that something persistent has gotten corrupted (this
problem
continues across reboots).
I have found the aggregate device info in .GlobalPreferences.plist
and the
com.apple.AudioDevicePrefs.plist, but deleting them does not resolve
the
problem (I have gotten the byhost ones as well).
So... What am I missing; what magic is required to flush all of the
aggregate device state so that I can start over with a clean slate.
I would
rather not have to wipe the machine....
