Hello all.
I'm trying to support the kAudioUnitProperty_SupportedChannelLayoutTags and kAudioUnitProperty_AudioChannelLayout Properties in my AudioUnit (subclass of AUMIDIEffectBase) to support surround channel layout routing in my AU.
When I try to debug through my component, I notice that neither kAudioUnitGetPropertyInfoSelect nor kAudioUnitGetPropertySelect are ever called with the above Property ID's.
LogicAudio is my Host application , running on MacOS X.4.11 using XCode 2.4.1. I can breakpoint within the component entry dispatcher, and I can hook on other properties without problem.
Am I missing something? Should I raise some flag, or somehow modify the 'thng' resource describing my AU, or somehow report that I support these properties to be asked for them?
Thanks for any hint!
