Sound routing, eh ? I got no clue at all if the internal wirings would/do allow this. Ah, well. If the hardware is able to record from fm, then it should be possible. silly me.
No, what I meant was record from the radio and send that to the optical out... come to think of it, that would require full-duplex capability which I asked about before, but didn't get an answer. Can the H1x0's do it?
