I can see lots of historical posts about issues with Samsung Frame and Sonos Arc, but most topics are closed (some implying the issues are fixed). 
 

Well, I have a brand new Samsung Frame (2024) and a brand new Arc, both running the latest updates, and it most definitely still a problem. 
 

Things will work fine for a day or so, then sound will stop being sent from the TV to the Arc. The TV still knows Arc is there, and it’s selectable as the output for the TV, but the Arc doesn’t seem to receive any sound. After a few seconds, the TV will flip back to sending sound via the internal speakers again. I can re-select Arc as the output get no sound and a short time later it does back to speakers. 
 

When in this state, it doesn’t matter what input is used, what the sound format is (eg Atmos or not). The volume control on the TV brings up the overlay saying “Sonos Arc (HDMI-eARC” but the plus and minus icons are missing. 
 

No setting changes on the TV fix it. No change on Arc settings fix it. Restarting th Arc doesn’t fix it. Only powering off the TV for a few seconds then powering on again brings it back. And after a day or two we’re back in the same situation. 
 

I can’t tell if the problem is with Samsung or Sonos, but it’s definitely not working properly. 
 

Does this match the experience of others?

Have you ensured TV Autoplay is ‘on’ in the Arc settings in the Sonos app?

Hmm, sounds like a good idea. The Frame/Arc is back in the no-sound state so now would be a good time to try this!

I know I’ve seen this setting in the past, but I can’t find it in the new app. Surely they’ve not taken this setting away!?

It’s still there: 

Settings / SRoom containing the Arc], then scroll down to Home Theatre heading. There you will see TV Autoplay.

Ah, thanks, the setting was missing. I had to update the app in the AppStore and now I have the settings. It looked like the setting TV Autoplay was enabled, but I toggled it a few times in case. 
 

Selecting TV from the “Your Sources” section seems to bring sound back without requiring a TV power off-and-on so at least that’s a more bearable “fix” until I get to the bottom of this or a proper fix.

Hi James, I have the same situation here. Both systems are not working together properly. SONOS please talk with SAMSUNG! SONOS has a lot of other s*** at the moment…
