Process for tearing down audio controller
Sometimes I need to tear down AEAudioController completely and create a new one with a new audio description. What parts of the audio graph am I responsible for removing when I do this? In particular:
1) all audio channels (via removeChannels)
2) all audio channel groups (via removeChannelGroup)
3) all filters (via removeFilter)
It would be nice if the audio controller just removes all of these in dealloc, but I don't know that it does.
