Arc keeps disconnecting from Samsung TV

My Arc has been having issues with connecting to my Samsung TV.  Prior to switching to the Samsung, I had a older Vizio.  The connection issue happened with the Vizio as well.  I would just unplug the HDMI and/or unplug the Arc and the audio would come back.  That is not the case with the Samsung.  The option for Home receiver Audio output on the TV goes away.

 

Also, I do use a Nvidia Shield for my content.

 

Is this a cable, TV, or Arc issue?

 

I have replaced the HDMI and seems to still happen.

Sure. After one of these disconnects, submit a system diagnostic and call Sonos Support to discuss it.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your Sonos system and network.

It looks like a lot of people are having Arc disconnect problems.  If you have a streaming device hooked up, a CEC blocker will fix the problem.  The blocker device has to be in-line with the offending peripheral, as far as I know.  I don’t think putting a CEC blocker in line with a cable or satellite box will work.
If you are getting disconnects without a streamer in place, then it’s a real mystery to me.   Since an Amazon Fire Cube is the culprit on my Samsung NEO, a CEC blocker stopped the disconnect.  Interestingly a Roku Express doesn’t cause the problem.  I think, therefore, it is incumbent on Amazon or Sonos to tix this bug.

This is the first I’m seeing this solution about a CEC blocker, and it seems logical to me, the AppleTV we use is likely the culprit.  My Arc disconnects almost daily, and I have to unplug everything and run the TV Setup option from the Sonos app, which is a pain for a wall mounted TV.

There’s only one HDMI cable routed from my TV to the storage cabinet, so I use an HDMI switch for all of our devices (other than the ARC, which is directly connected to the TV).

If I use the CEC blocker, I’m worried that will interfere with the automatic switching of the HDMI switch, unless I put it on the output of the switch?

Thanks!
