It has been reported here that the AudioInputAnalog on the 4.0 "does not work good". In my experiments, "does not work good" == "doesn't seem to work at all". As far as I can tell, no audio data is ever emitted from the class.
It looks like there was a commit with some work to make it happier https://github.com/PaulStoffregen/Audio/commit/5d6cdd51aae14750047bb468fa3d385218de808a
I'm not opposed to spending a bit of time trying to hack on it to get it working myself if that is remotely feasible. Does anyone know the current state and what stands in the way of making it work?
