Beam: Keeps switching back to ARC from Bluetooth - how to stop?

Hi. I have an LG C8 OLED TV and a Beam, connected Via HDMI Arc. I also have some Sony Bluetooth headphones. Whenever I try and play the TV audio via Bluetooth after 2 seconds it switches back to Arc. Is there anyway to prevent this? I have to pull the HDMI lead out of the Beam, but can it be disabled via the app or some other way? Thanks.

    I have the same problem as Badgercop. It seems that this is pretty common as shown by these similar threads in the sidebar to this thread. The best, though not optimal, solution seems to be to turn off the HDMI-CEC connection on your TV. It would be nice of SONOS would fix the APP to handle this situation. The problem is not solely with LG systems - both Samsung and Sony are referenced in the other threads.

    My solution

    I bought a smart plug and use it to shut off my Sonos Arc when I don’t want to use it.  I control the smart switch via Apple Home but could be Alexa or Google controlled too.

    I have a hearing  aid transmitter connected to Optical output on the TV and had the same problem you had.  I could not switch settings on Sound to TV speakers and Optical while the Sonos Arc was powered because it would continually switch back to HDMI/ARC after a couple of seconds.  

    Turning off the Sonos Arc soundbar with the smart switch, the LG automatically switches back.   You can navigate back if needed to your Bluetooth option.

    Why not choose to just switch off Simplink on the LG TV, rather than powering off/on your Arc? Would that not have been easier, particularly as you have to goto the TV settings anyway to switch to Bluetooth or TV/Optical audio-out.

    Normally I don't need to do anything - the LG keeps my Optical output operating - Optical to my small Bluetooth transmitter

    Turning On my smart switch brings back the Sonos Arc and the Optical/Arc switches automatically 

    Gong through all the steps to turn off SIMPLINK more involved and a PITA

      almost 2 years ago came across this problem ( LG 65 inch OLED + beam + airpods)

      no resolution since then?

      Unacceptable. 

      Bad Sonos, bad.

        Whether you were to switch off CEC control on Sonos, or deactivate ‘Simplink’ on the LG TV - it’s still means a user will have to interact with either the App, or the LG Settings to switch to Bluetooth audio output - As the LG TV already supports switching off ‘Simplink’, arguably, there isn’t anything that Sonos needs to fix here.

        If I switch off Simplink, the TV seems to re-enable it anyway, so even that isn’t a solution for me. I need to unplug the Arc altogether.

         

        I like the smart plug idea further up the thread - thanks for that. That’s at least a semi-nice solution.

        That’s strange, I have two LG TV’s here and if I toggle off Simplink to use Bluetooth - it stays off with either a Beam or the Arc attached?

        I just double checked. Definitely re-activates for me, after a couple of seconds.

        This is on an Xbox Series X → LG C1 → Sonos Arc.

        The Xbox is not relevant. This is the first time I’ve ever come across s TV where the HDMI-CEC protocol can’t be switched off - the LG C9 and B9 models both work fine - and once ‘off’ it should also disable ‘auto-power-sync’ and the user can then go to the sound out menu and select the sound out options - internal TV speaker, Optical, WiSA soeakers, Bluetooth etc.. I accept those outputs can’t be selected until CEC is off, but never seen a TV that re-enabled CEC by itself - that sounds like a faulty TV to me.

        Think I understand the issue now. I was disabling HDMI Simplink, but I still had eARC enabled in the sound settings - it evidently re-activates it if eARC support is enabled.

        With eARC disabled, Simplink stays off.
