Yea, how though?

I can't seem to find a multichannel vorbis encoder that works, plus you
got the physical transport.. multichannel vorbis means you are going to
have to use analog outs... I think. To get it down a spdif pipe you are
going to want to use ac3 because the other end (your reciever) generally
only understands 2 channel spdif and ac3 5.1 or 5.2 or whatever. Feeding
it 3 or 4 or 5 channels independantly will jsut confuse it.

So you need to rencode it to ac3 5.1 on the fly. although there are libs
to do this, I know of no code that ties it all together.
