Bill,
I am confused by your answer here....

For example, if I had two stereo pairs and two mono outs, I'd
report 4 as my
number of outputs, and { 0, 6 } in response to
SupportedNumChannels()
This is definitely wrong, as not a single bus can be set to 6
channels. Part of the motivation of having this property was to
describe alternate settings of channelisations (Which this is not
really a case of). Can I ask this - why are you providing 2 stereo
pairs and 2 mono outputs?

- Host interrogates the Audio Unit for number of output
busses via
kAudioUnitProperty_BusCount
Yes
- For *each* output bus (element on the output scope), Host
interrogates the
Audio Unit for the element's StreamFormat via
kAudioUnitProperty_StreamFormat
Yes
This answer is yes? I thought that in the answer above you were saying
that the supported number of channels applies to all busses. If it
possible to inquire the number of channels for each buss using the
element field on output scope can you please confirm this and if this
is true then I don't understand why a single buss cannot be set to 6
channels.
Thanks,
Jeremy
