I've never had auditory hallucinations, but something weird happens to me when I'm having withdrawls. If I close my eyes, (try it, you'll see remainders of light from what you've been looking at), the 'static' looking light and black form weird images. It's scary as hell some of the things I see (people, monsters, babies, etc). I never feel like I'm going crazy, it's just got me so confused as to how that could ever happen.
Funny thing is, my friend (who's been drinking around the same amounts for just as long) has experienced the same thing.
