Not always sound on Sonos arc with Samsung UE50J6240.

I recently got my Sonos Arc and Sub. But my Samsung UE50J6240 isn’t always sending threw the audio to the Arc. 

I have the Sonos Arc connected on the HDMI ARC port. And I got it working when I installed the Sonos ARC. But when I turn the the TV off and on again then it will not connect to the Arc. I have to psychically shut down the tv (disconnect the power plug from the socket). When I turn the tv on again then it will connect to the Sonos Arc and send threw the audio.

Is there something I can do? I want the TV to send the sound threw HDMI ARC when I turn it on and the put the Sonos Arc on the TV source.

  • I tried changing the sound output on the TV to receiver when it’s not sending. Then it will try to connect to the receiver (ARC) but eventually it won’t send any audio.
  • I tried searching on the tv for HDMI-CEC /Anynet+ devices. But no result.

Thanks in advance!

Hi @MikeMaster, thanks for the update and for sending another diagnostic report, upon checking, It shows HDMI broadcast blocked error, Sonos player cannot establish an HDMI-ARC audio connection because another HDMI device is interfering with CEC message traffic between the Sonos Arc and the TV. Are there other HDMI devices that may cause interference that is connected to the TV? The Sonos Sub also shows Bad cloud health or not good connections with the Wi-Fi network.
