For some reason the realtek settings only give the option for 2 channel optical audio (unless I'm missing something).
If I wanted surround sound with bitstreaming via the optical output would I have to get a soundcard like I had to do with an atom ion zotac? That seems kind of silly.
I had seen a better discussion of bitstreaming but this has some information for graphics cards. http://www.tomshardware.com/reviews/geforce-gtx-460-gf104-fermi,2684-3.html. The Realtek chips vary in functionality provided.
