Nothing works on the Onkyo Multi-Zone AVR driver for the TX-RN710. I suspect it has something to do with eISCP header data, perhaps the version number. I thought about setting a Wireshark capture of both the Onkyo AVR and the Onkyo Multi-Zone AVR driver in order to spot the differences, however it would be somewhat difficult since the Onkyo's Ethernet port on the switch would have to be mirrored.
Perhaps a version parameter setting maybe needed.
I noticed that the parent driver "Send Msg" throws an error.
