I upgraded my KD- 43 XF8796 to 6.652 as I was having intermittent ARC problem with no sound to my Yamaha rxv673. I set it up to work and the next morning, there is no output to the amp. It still switches on the amp but no sound. I have tried all solutions in the forum, including the 9 step solution Sony suggested which includes clearing the cache and doing a factory reset. It would work after the reset but not the next morning. Turning the amp on & off does not bring the sound back bur sometimes a soft reset works but this is too unreliable!
i can get sound via the optical link but I gather it does not transmit full 5.1 digital? Can someone enlighten me?
