hey, that is cool to know (as a non-osx user, i wouldn't have expected something like that to exist, but i think, i know quite some people
who could benefit from that). just in case you know: do you have an idea how this system deals with the fact, that each of this cheapo soundcards have their own clock?
does it use one as the master clock and does apply a samplingrate
conversion to the other in order to sync it? i am asking, because i would like to know, if any decrease in sound quality is expected when you use aggregate.
I've used it a couple of times to get some extra outputs from a
laptop, and it has worked fine but I haven't used it extensively.
There are options to choose which clock source is used, and options
(for each physical device) to re-sample the audio so it seems that it
will re-sample if you choose, or not if it works ok without - I guess
that would depend on things like the abilities of the cards and their
drivers.
It has been around for a while - maybe introduced in OSX 10.3???
