I connected my Beosound 4 instead of the Beocenter 9500 to test it. The Beosound 4 does not in fact have a choice a A.Opt 4. It looks like it has 0, 1, 2, 5, or 6 available.
So, I tried putting the Beosound 5 into Audio Slave mode and putting the Beosound 4 into A.Opt 0, with my Beosystem 3 in V.Opt 2, but then no audio source worked at all – only video sources worked via my Beo4 or Beo6 remotes. It I played a CD direct from the BS4’s CD button, it played, but no sound.
