Hello, DandoKhaan! Welcome!
Okay, I'll see if I can help you out a little bit here. I do not believe you can send an Aeon in for sound. If it doesn't have the option normally, then I don't think Ultra will do sound for it. Not from what I've seen anyways. However, there is a member here (Natalia, I believe) who has recently installed a soundboard in an Aeon herself. There is a thread somewhere detailing her end results, and a little of her progress. I believe it's in the gallery, but I don't remember the exact results. If you search Sound and Aeon, I'm sure it will come up though.
She may be able to help with how to go about installing one for yourself, and I'm sure there are other members here with more experience than me who can help in that regard.
Hope that helps you some!
