What effects they cause don't really matter, it's how they are initiated. I always thought visual genjutsu are genjutsus that affect through the eyes, while Dojutsu are genjutsus that are initiated from the eyes. So it's possible for an auditory genjutsu to be initiated from the eyes.

I believe that Rinnegan is not immune to genjutsu. Sasuke was immune to IT because he blocked the IT light with his Susanoo, which was enhanced by his Rinnegan. The Rinnegan has the ability to understand jutsus easier, which I believe can also cancel genjutsus easier than normal people do. This is also why Kakashi and Itachi didn't use genjutsu, because they know it will be less effective than ninjutsu.
