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.

What model Samsung TV do you have?
Disconnect everything from your TV including the Arc and unplug the TV and Arc from power for a couple of minutes. Plug them both back in but keep them disconnected. Make sure Anynet+ is enabled in the TV settings. Run TV Setup under the Arc’s settings in the Sonos app and follow the app instructions. When the app instructs you to, connect the Arc to the TV’s HDMI ARC port using the Sonos-supplied HDMI cable. After the Arc has been successfully connected to the TV, connect the Nvidia Shield to the TV.
I have this also on my Samsung TV.
My workaround is to power-down the Arc and then back up again.
It’s a right pain and the above is not a long-term solution.
I hope that Sonos come up with a fix.
I am having the same issue ever since I switched to the Samsung C10 and the arch when upgrading. Happens about every 35 minutes or so it seems using upgraded high quality hdmi. Still have yet to find what is the issue. Sonos needs to send a fix. This would be great.
Having similar issue with 2 different clients both have a little older Samsung TVs and they are using optical not ARC and they are not getting tv sound anymore. Stated about the same time. Was an update pushed that broke the optical connection?
Perhaps by Samsung, but not by Sonos. There are too many PLAYBARs and PLAYBASEs, not to mention Arcs that still use an optical input.
However, I would actually be expecting that somehow those TV sets in question got changed from a Dolby Digital output to something that has more bandwidth than can be carried by an optical cable. A simple reset of the TVs output in the settings, or a reset of the settings of the device that is feeding the TV is where I would be looking.
Everything has been reset and defaulted. Reconfigured. Sonos keeps saying no hdmi detected even though it’s been told it’s using optical no arc available. As mentioned these are older Samsungs that don’t have any new firmware updates available.
Same issue here. The issue is intermittent. But when it happens, it flip-flops two or three times and then seems to settle down. My setup is a Sony Bravia 4k UR2 and an Arc, two Fives and a Sub
My Arc wouldn’t stay connected to my Samsung Neo and the cause turned out to be an Amazon Fire Cube that I used rarely, apparently a CEC issue. Disconnecting the Fire Cube fixed the problem; no amount of tinkering with its settings worked. However I discovered a device that does fix the issue: The BlueRigger CEC less adapter. It prevents CEC from working as it’s missing a pin. It is female to male, fits inline with the HDMI cable from an offending device, if there is one, and so far it works. No, you can’t switch to the Fire Cube by pressing the home button on its remote. You will have to switch inputs manually. So far, I consider my $15.99 spent on Amazon worthwhile. FYI, a Roku Express doesn’t seem to have the same problem.
i’ve also been having this issue as of the past week. Likely a red herring, but after connecting to my Samsung TV with Apple AirPlay, it’s now been consistently disconnecting my Beam + Onex2 setup (in that I cannot choose HDMI receiver as an option for my sound output).
Just happened today after it first occurred. It was fixed after the first occurrence by disconnecting all HDMI inputs and power from the Beam and the TV, then reconnecting power and the HDMI for the Beam first. I had also updated Samsung’s TV firmware.
Really annoying. Hoping that this is just a hiccup and that it only occurs for a few more times. If it persists, it is NOT a long term solution.
I am having the same issue with my new Samsung TV. Very annoying. I can’t believe Sonos is not addressing this. I just ordered this BlueRigger 4K HDMI CEC Less Adapter (UHD, ARC,1080p, Ethernet, Male to Female CEC Blocker) -Compatible with HDTV, TV Stick, Chromecast, Nintendo Switch, Xbox, PS5, Laptop, PC, Game Console, Soundbar https://a.co/d/al0W1Ao
Hopefully, it will resolve the issue.
Same problem. Keeps disconnecting. HDMI sound option not showing on my Samsung Q9.
I open the Sonos app and find the «TV» option in the app. When I adjust the volume with slider in app, the Sonos activates for like 5 seconds and switches back to TV sound.
