DD3 has auditory processing problems.
Not sure what you would like to know. DD is now 16, still has some problems, but manages to have a good quality of life and laughs off any faux pas she makes due to her many issues. (dypraxia, dyslexia, auditory processing, memory issues, etc, etc.)
Just as an example of how her auditory processing affected her: When she was younger, I could never say a general instruction, such as "go and get dressed" because it was all too much for her. I used to have to say, get your pants on, wait for her to do that, then "get your vest on", wait again, once done, "get your socks on Etc, etc,....... Life was a lot slower going than for her peers and siblings! 
Lots of things we had to break down so that she could understand it. How old is your DS? If he is at school it can be really frustrating for them. DD used to hate things like "quick maths" because she could do it, but would still be processing question number 1 when the teacher was going onto number 5!! She hated it and we really had to make a fuss at the school about this. They would get the class to read out how many they ahd right and DD only ever got the first one, because she took so long to get it into her head and work it out, then she would have the humiliation of having to announce this to the class. Only discovered when she repeatedly had tummy ache on Friday mornings!
Sorry, don't know if this is of any use, if you ahve specific questions I will try to help you.
