Indeed, I am ending with a *very confused aggregate device* that
"lost" it's output device!!
What am I supposed to do in this situation??

OK, that is good to know. But if even Apple GarageBand does not do
the *right thing* ??
Sorry but you do not anwer the basic question:
- an application (like Max/MSP or Ableton Live) or even the user
using Audio Midi Setup is changing the SR of a *real* device used in
an aggregate one.
- the aggregate device get confused: it's output part (for example)
just disappear .
- the aggregate device then is not "duplex" anymore!!
- trying to setup back the current SR is not a good strategy OK, OK
- what I am I supposed to do in my application? (which is actually a
server that cannot warn the user so easily). Just fail??
I understand that maybe a lot of applcations are not doing the right
thing. The question is WHAT TO DO NOW?
Thanks again
