Sonos ARC (Losing HDMI-ARC connection)

Hi 

 

My Sonos ARC has recently started losing connection to my LG TV every time I turn off/on the tv. (LG 65NANO886)

 

To reconnect i have to redo the complete setup process to obtain again sound from HDMI ARC.

 

Already have the last software update, but still have the same issues.

 

I have run a diagnostic which is 1479387262.

 

Any help is appreciated.

Thanks in advance.

    Hi @Anonymous

    Welcome to the Sonos Community!

    First, please try unplugging the TV from power for at least 2 minutes. Forcing the TV’s software to reboot can often clear up such issues.

    If that hasn’t helped, please try disconnecting the Blu-Ray player from your TV - if doing this prevents the Arc from disconnecting from the TV, then I recommend you look into how to disable CEC features on the Blu-Ray player. If it has no such configuration options, you may need to get a CEC-less adaptor - but only do so if disconnecting the Blu-Ray player actually helped.

    I hope this helps.

      Hello @Corry P 

      Thank you for you time and collaboration fixing the issues with the continues disconnecting of the ARC and the TV. Went directly and disconnected the CEC features from the Blu-Ray and indeed fix the issues!!

       

      Thanks again!!

          Hello @Corry P 

           

          Sorry to say but the fix is not working any more.. is back to losing the connection between the TV and the Sonos ARC in every power cycle (ON/OFF)

          I have run another diagnostic which is 11742033711.

           

          If you have any guidance will be much appreciated. Thanks!
