Hi Johan,
Thanks for your reply! I have the manual however I find not the right setting.
I changed now to Source Center as I only need N.Radio or N.Music over ML.
Never the less nothing happens. The A6 is connected as primary. Secondary is non.
I will not get any sound from the A6 to my via BLC connected Beosound 9000.
Will try other settings but these makes for me the only one which make sense.
