By reakinator:

I completely disagree and I think I could find a post on pd everywhere where you had mentioned that you wanted to inform the user of property changes. That is why the PdAudioPropertyChanged type is in there, so it should be used.

If the user asks for 1 input channel and gets 2, he should know. What if he then decides to only send audio out of the [adc~] to the first channel, thereby only hearing anything from the left speaker?
