Perhaps you failed to read the original issue. The issue is that at least on some TVs across all the manufacturers, the TV fails to successfully snd permanently switch to any sound outputs from own menu (as intended and designed), because Sonos seems to reset the connection and reassign it to itself essentially stealing it after a few seconds. I want decide what sound output to use. Not Sonos. If I want to use the headphones connected to my TV, I should be able to do it.

No pulling of hdmi cable, pulling the power cable and other ridiculous solutions should be necessary. Either implement a software fix/workaround or add a soft switch in the app (other soundbars can be turned off using the remote or built in power switch) to power down the bar or disable it, if the software fix cannot be implemented.

The soundbar can’t steal the the audio. The soundbar can regularly ping the TV to let it know that it’s there and ready to receive audio, and I suspect many soundbars do not do this. It’s ultimately up to the TVs firmware to decide where to send audio. If the TV wants to decide to send audio because the Sonos soundbar, or whatever soundbar, just pinged and let it know it was ready, regardless of where the user said it wanted to send audio.

That said, I don’t know for sure what the CEC recommendation is on this. It may be that TVs ARE supposed to transfer audio whenever they are pinged by a soundbar, and maybe soundbar’s are only suppossed to ping during setup or otherwise triggered by the user. From what I’ve seen CEC ‘rules’ tend to be rather loosely implemented with the manufacturers choosing what they think should happen, often in conflict with other connected device, rather than a well defined policy that gets them CEC certification.

It seems the Sonos way of using CEC (maybe “pinging” more often than other manufacturers do) is allowed by the CEC guidelines. Sonos might be of the opinion that this feature is beneficial to most users, that buy an expensive soundbar and want to always use it - remember Sonos sells mostly to affluent but not always tech savvy customers. Your use case of buying an expensive soundbar and still wanting to use the cheap built in speakers looks like a minority use case, though it has been mentioned on the community especially for users that would like to use a head phone (for which the Sonos Ace now is an option).

Your only option would be to temporarily turn off CEC (called Anynet+ on Samsung TV’s).
