You are using the same API calls that AMS uses, so my guess is that
you still have some issues with your code for creating the aggregate
in the first place. Not that it's your fault, mind you. This process
isn't the best documented thing in the universe.

Hi Jeff,
by activate I mean setting the aggregate's sub devices to an active
state. when I create an aggregate device it always has 0 input an 0
outputs and I can neither use it in my app nor in AULab. the
aggregate device editor in AMS has this check box "use" for each of
the subdevices. only after I have manually set this check box in
AMS, I can play sound through my aggregate device in other
applications. now the question is, how can I programatically do
what AMS does when I click that "use" check box for a subdevice.
thanks,
christoph

What do you mean by "activate"?

the last thing I am trying to figure out is how can I actually
activate an aggregate device. everything's fine with its
creation and it shows up in AMS. however, I can't use it in my
app unless I manually activate it in AMS. I'd like to do that
programatically. so what's actually done when you click that
check box in AMS for a device in the aggregate's sub device
list. do I have to set a certain property on the sub device?
