Hi Bill, and list-
Thank you for the suggestion. I have taken your advice, and even
found some more tips from the archives. Only one question remains
for me. These properties must be overridden I assume, in order to
have some meaningful purpose. I am creating a new output class
that supports these (i.e.,
MyPlugin::MyOutputClass::GetAudioChannelLayout etc.), but when I
test in auval, these layout properties are not listed as they are
in the MatrixReverb example! I feel slightly disheartened ....
These should be supported by an output class of type AUIOElement,
or am I way off?
Yes - that's what the reverb uses - you can trace the call down from
AUBase::DispatchGetProperty - you should be able to locate your
failure easily enough.

You should be using the AudioChannelLayout properties to describe
to the host the order of your channels - if you run auval on
Apple's Reverb you'll see tests for these showing up. There are
two properties to support:
AudioChannelLayoutTags
AudioChannelLayout
There are some comments in the AudioUnitProperties.h (and
implementation support for this in AUBase classes)

Hi Olivier and list,
Thank you, I have had pretty good luck with surround and DP.
Although
I have another problem that isn't necessarily AU related, however
maybe someone else has experience troubleshooting this issue.
Does anyone have advice for providing audio buffers when DP makes a
render call? My assumption was that the channel order in DP's Audio
Bundles (ie. L>R>C>LS>RS) would correspond to the ordered buffers
supplied by the AU (ie. mData[0]>mData[1]>etc.). However, when
trying
to test one channel at a time, this does not seem to be the case -
weird stuff happens such as two channels playing when only one is
supplied signal! Has anyone else had this type of issue?
Thanks everyone for your help!

Hi Chris,
You can try Digital Performer. It handles well surround.
