Connection for Surround Sound, Multiple Inputs?

[Confused]

F1eng is quite right, Toslink is not able to transfer HD surround formats. However, when I spoke to the Devialet engineer at OAC, the reason he mentioned for non HD surround support was licencing costs. Thinking about this though, you need some method of getting HD surround to the Dialog, and without an HDMI or SPDIF input, you are just left with the optical input, so irrespective of the licencing issues, I can't think how this can be done anyway.

EDIT - My little Brain is now inventing a 7.1 TrueHD version of Devialet AIR, might be a little tricky to implement though ......
