SonosArc sync/compatabilty with Sony Bravia Oled
My Sonos Arc keeps losing connectivity/sync with my Sony Bravia Oled tv, it is connected with the eArc hdmi. I have to keep unplugging power and hdmi and then reconnecting power and hdmi to get the Sony to play sound through the audio system. Otherwise the Sony message says audio system is unavailable and switches back to tv speakers, sometimes the Sony shows the audio system to be connected but I get no sound, sometimes the Sony shows the audio system to be connected and I get sound but cannot control volume with the remote, I basically have to reset the Sonos Arc by unplugging it before every use to get everything to sync. I want the audio system to connect automatically every time without having to reset the Sonos Arc force for every use. I have a friend with the same systems and he has the same issues. Any ideas on how to correct this problem?
