I have a equal looking problem. Can not switch to A.Aux directly from my B&O passive IR-eye.
First I have to put the Passive system in the kitchen to cd, radio... whatever, and then walk to the Beosound 3200 and switch this unit to A.Aux with the Beo 4. Then it works to get A.Aux music from the Passive amplifier.
This is the only way to get A.Aux music from the Passive in my kitchen.
Yes, I kown my spelling is horrible…
