See, my son who everyone thinks is ASD but me, appears to not be listening at all, but if you say, what did I just ask you he is able to repeat back word for word any length of question, even very complex questions with multiple parts... and then he answers them. It's not that he doesn't hear, it's that he doesn't notice I think. I personally think it's an ADHD thing, but just something to compare against your own experience with another kid with the same diagnosis.
