My setup is working pretty much like yours.
But I'd like to be able to switch outputs, preferably while playing, so
I can decide to listen to music via the TV speakers now, or watch TV
using my 5.1 setup.
Additionally, in a perfect world, the encoding of the original audio
source would not matter and be converted as appropriate for the ouput
(TV vs. 5.1).
Maybe jack is what I am looking for?
cheers,
stefan
