i would have thought this was utterly essential to hosting an AU, so i
assumed you knew about it already.
the property in question is: kAudioUnitProperty_SupportedNumChannels
a plugin is not required to support this property, but if it does not,
it is expected to deal with any Nin/Nout (note the same N).
i don't call this directly but use CAAudioUnit::GetChannelInfo()
there are docs online about how to interpet the numbers you get back.
