What properties need to be set to make it happy? I imagine that once
it's configured it probably behaves in a similar manner to the
DefaultOutputUnit?
I think the DefaultOutputUnit does some fancy footwork to convert the
canonical format to the device format - would a HALOutputUnit do this
by default or would we have to connect it to an Converter before wiring
it into a graph for example?

What documentation/features of this AU do you need to understand? I'm
still hoping to get some more docs done, but in the meantime the list
is a great forum to answer.
Please, rather than an essay/diatribe - just brief one liner points
are much better (and yes, I know we blow in this area !!! :-)

Hi James,
Well I guess I could try the mixer - but I'd like to keep my signal
path as short as possible :-) I'll try some of Jeff's suggestions in
the mean time.
The lack of doc on the HALOutputUnit is a big reason none of my apps
have an Audio selection preference.

You might try inserting a mixer unit before the output. Numerology
does lots of connects and disconnects to the StereoMixer all the
time w/ no problems.
Or you could try using the HALOutputUnit -- but good luck
trying find any doc on it!

I've got a bug in my app where it will freeze the entire system
(except the mouse still moves). It seems to be the
DefaultOutputUnit that's getting confused, but I'm not sure what I
could have done that would cause it to block the HAL IOProc (which
is what I think causes this problem). It seems to happen when I'm
messing about attaching and detaching AudioUnits to the
DefaultOutputUnit.
Thanks for any sleuthing tips,
Robert.
