I am trying to use the Avia disk with my rxv-1000 receiver, but unless I am playing the internal tones from the receiver it will not lt me adjust the speakers. I can adjust the sub but when I scroll through the speakers using the level button on the romote all the speakers show a double dashed line and will not let me adjust. If I hit test then it shows the speakers level setting and then I can adjust. How can I use AVIA with the situation? is there something I am doing wrong? have other Yamaha users run into this as well?
