Wrong.
There is *no* soundcard on the market that has AC3/ Multichannel output from
games etc.
What you refer to as digital out, gives multiple 2-channel outputs, but not
a single 6 channel one.
The only time the main digital-out channel gives more than 2 channels is
when the soundcard is passing a AC3 stream or other multi-channel stream
from the software.  This doesn't happen in a game.

Whan I want to do is to activate digital out on mu SoundBlaster 5.1 and then
take those three 2-channel digital outs and combine them into a single
signal.  This can then be sendt to a reciever the same way as you would send
a ac3-signal, through a single fibre.
