Hmmm, I think this might be something you could consider a bug in the AU
SDK. Buses are referenced by "element", right? So when someone Gets the
SupportedNumChannels property, the element argument is supposed to specify
the bus index, correct? It is ignored in AUBase::DispatchGetProperty and
DispatchGetPropertyInfo, and also of course not passed along as an
argument to the SupportedNumChannels method, so I guess there is an
assumption that the property is the same for all buses, which to me
doesn't seem a valid assumption. I think that the SupportedNumChannels
should have another argument specifying the element and the Dispatch
methods you pass that along, but maybe I'm wrong about this, I haven't
tried multiple buses yet...
