So I found the problem but I need some help to solve it. The AVR-Receiver can be used in 3 modes

5.1 W/ Zone 2 - (Plugin works great)
7.1 -W/ Front Height Speakers (Communication error *** Lup Failed to Start)
7.1 - W/ Rear Surround (Communication error *** Lup Failed to Start)

I not sure where to find the problem in the code
