I believe the speakers are analogue, but I don't know for sure - there's nothing in any documentation to say so, and I couldn't find anything relevant on the net. They're a pair of Altec Lansing "expressionist BASS", black desk standing speakers that look a bit like daleks (mechanical badies from the british science fiction series Doctor Who). I've set both S/PDIF and "S/PDIF Default PCM" to muted. No joy. > HTH > -Robin -- Alan Mackenzie (Nuremberg, Germany).
