It's been a while since I last looked over that code, but I recall
the biggest single issue had to do with it not handling overloads and
other time discontinuities at all. I think it may also have had some
issues with properly handling overrun/underrun of buffers in it's
synch code.

OK - thanks, that's good to know.
What kind of things should I be doing, to make it more robust? At
the moment, I don't really know what's going wrong with it (I
cannot see any errors). Granted, I've not gone through the code
with a fine tooth comb yet (looking for functions that might return
errors, that don't, or are not setup to return them to the
console)... still, I feel it's a bit like looking for a needle in
a haystack.
What should I attack to try to get it working? Im happy to be
told to 'go read stuff' as well - since I do want to learn about
CoreAudio.

ComplexPlayThru is a bit on the fragile side when it comes to
synching the input to the output. When it goes off into the weeds,
it will often end up like this (or just outputting silence) as
it's recovery mechanisms are a bit lacking.
ComplexPlayThru exists to illustrate the basics of setting
something like this up and just getting things working. Being
sample code, it has rough edges and probably doesn't handle errors
or other exceptional circumstances too well.

I fired up ComplexPlayThru (on a G5, with external iSight, FW)
and attempted to use it.
I get about 1s of correct play through audio, followed then by
continuos buzzing.
Is this the expected behavior?
