HELP PLEASE!!!\n\nRecently I moved house and when I setup my Yamaha RX-A3080 it automatically upgraded firmware to version 2.01. Now only front, centre speakers and one sub works. I spent hours playing around with settings, triple checking connections etc nothing. Previously it's was setup 5.2.4 configuration and loved it.\n\nReason I know it's the firmware is I swapped it over to an RX-485 same deal. Front, centre and one sub only.\n\nI have sent both to Yamaha in Bangkok explaining issue but they seem stumped.\n\nAny help \/ ideas greatly appreciated.
