This topic is 2 years ago !

And the solution proposed is to switch off every time the CEC control on TV or add a switch??? 

The ARC costs 1000€ !!! 

The problem is that if I choose to listen the TV on headphones or TV speakers, the ARC overtakes destination and the sound go only from ARC.
The problem is known by SONOS and for over two years!

When you can solve the problem???

Same problem here. 

I purchased a LG C2 83 inch+ Sonos Arc +Mini Sub + 2xERA300.

I believe it can be legitimately disappointing that a 10kCAD system purchased in 2023 cannot let people use their Bluetooth headphones on their TV, or create a party where some people play Smash Bros on the tv speakers while the others hear some music m through the Sonos system.

Those are simple, common use cases.

Each time I select another audio output, the LG reorients the audio towards the Sonos Arc, whatever the options I change, I don’t care who is responsible of what, each time I call them, those two companies say to me the other is responsible.

The incompatibility between those two major manufacturers through the ARC/CEC connector is simply a shame, especially considering I am using their flagship systems.

Come on guys, find a proper solution, through the app or anything else. TALK. No workaround is to be found for now.

I give myself (and Sonos/LG support) 5 more days to find a workaround (“CEC Less” adapter gives no proper result), if no satisfactory solution I’ll give my Sonos system back to Bestbuy.

    The challenge here is CEC, not Sonos, per we. The design specification of CEC, which Sonos uses, in addition to almost every manufacturer of home theater devices, allows a single audio ‘sink’, rather than multiples. So if a Sonos device is reporting as an audio speaker to the CEC enabled system in the TV set, which the TV manufacturer has installed and programmed, then the TV assumes that there should be no other audio connections, which would include Bluetooth it any other headphones. This is not a ‘choice’ made by Sonos, nor the TV manufacturer either, it’s the way that all companies who are part of the consortium that approved the specifications for CEC approved the specifications, and subsequently have implemented it. 

    I have to disagree. Bose for instance, don’t have the same miscommunication issues with LG C2 TVs for instance. At LG support there is a clear note mentioning Sonos Arc is miscommuncating their “ID” through the arc connector, which leads to such improper, limiting behavior. Some manufacturers clearly implemented CEC a better, more convenient way.

      Reading this post I'm even more disappointed than I already supposed.
      Is incredibile and saddest because Sonos' answers exploit the fact that not all people are super experts. As the post above highlights Bose itself has come up with a solution to the ARC protocol. 
      Furthermore, in the face of a person who has purchased several expensive components, there is not the slightest intention of accepting an observation.

      This is not having customer attention.

      There is not going to be a solution in 5 days.

      Can you provide a link to where LG is stating that Sonos is miscommunicating their ID?

      And regardless, their answer doesn’t make a lot of sense.  If a user states that they want to send audio to bluetooth or TV speakers, why would it ever override that and send audio through connection and not what the user selected?  Even if you want to take the argument that users should be able to requests audio through the audio system connected through ARC (Sonos Arc) in this case, there is no reason to stop playing audio to bluetooth or TV speakers unless the user specifically states they don’t want audio going there anymore.

      I think you could claim LG is also not exploiting customer lack of understanding of the issue by claiming Sonos isn’t sending the right ID.  As I stated before, it seems pretty easy for a TV to just send audio to wherever the user selected to send audio.

      But this potential improper ID issue should be looked at further, as well as what is actually defined in the CEC standard around this.  Really would like to see more on this. From what I’ve seen, the CEC standard is rather vague and open to each company doing something slightly different.  It is also possible that both Sonos and LG are following what they view as a proper CEC implementation.

        “Can you provide a link to where LG is stating that Sonos is miscommunicating their ID?“

        The statement comes from the technician sent to me by LG. They did not want me to get that internal document but told me there is one mentioning Sonos miscommunication issue.

         “CEC standard is rather vague”.
        Ambiguity is not often a source of solutions. Bose and LG should simply… talk. Customers should not be the ones trying to find workarounds for such an issue without any clear guidance except the “unplug your hdmi connector” Sonos is giving to their customers.

           Hi all, about this problem not yet fixed… something special happened to me.

          if I turn on the TV and IMMEDIATELY the bluetooth headphones connect to the TV I can use them without the audio being picked up by ARC!

          If someone try it, let me know if it works for you too!

           

          For SONOS Support try it also you ;)
