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.

If AnyNet/CEC is disabled, then ARC is also disabled (so Sonos can’t be used as an audio output via HDMI).

Correct…You should not (hopefully) need CEC enabled if you’re switching the audio-output to anything other than the connected soundbar. Just switch AnyNet+ back on later to use the Arc.

I found an even better free solution.

I have the C2. There’s a remote with a mic. You can press the mic and say ‘Simplink off’, or enable voice recognition without touching anything.

If there’s no mic on your remote just turn off Simplink.

Hi. I have a LG 65QNED90 and when I turn off “Simplink”, about 2 seconds later the TV automatically turn ON Simplink again. I have Sonos Arc conected to TV (eARC port).

You would be best to discuss this matter with the manufacturers customer support desk - maybe give them a call. I have their C9 TV and that switches off Simplink with no issue and it stays switched off allowing the audio output to be changed. It might be the case that the TV firmware needs an update, but perhaps see what LG say about the matter.

Nope. The ERC is automatically re-enabled by Sonos and only when Sonos arc device is used in that port

Presumably it’s any device designed to connect to the TV ARC/eARC port that makes use of the CEC protocol. Usually (in most cases) it’s just a case of switching off CEC on the TV to then allow access to all other audio outputs.

Same issue - brand new Sonos Beam gen2 with 2 play:1 surrounds plugged into eArc on a 55” LG C1. Can’t seem to watch TV using the internal TV speaker, as it switches back to eArc audio after 2 seconds or so.

Guess we keep bugging Sonos for a fix…

Every poster in this thread has listed the TV settings menu as being the source of the problem. What in the wide world of sports makes you think the settings in the TV menu are something Sonos can fix?

Every poster here has listed disabling a feature of the TV so the broken CEC implementation on the Sonos will stop continuously grabbing the audio for itself. No other make of soundbar does this.

If a stretch of road is bad and every car needs the tires taken to half pressure for it then pumped up again afterwards you don't fix ALL the cars. You fix the road.

Which means switching off CEC - same if you use Bluetooth headphones or BT speaker with the TV - you need to switch it off when you’re done using it. There is nothing wrong with how Sonos works when using the audio return channel and CEC control… the TV settings cater for the switching between input/output already. So there is nothing that needs fixing here.

I have two different brand televisions equipped with Sonos. One can switch between Bluetooth, internal speakers, and Sonos via ARC easily, with no disabling of CEC. The other requires disabling CEC. Can you explain how Sonos’ “broken CEC implementation” is at fault for that?

It must be the first LG TV model then that doesn’t allow the user to switch off ‘Simplink’ - So you are likely best to speak to LG. I have three models of LG TV around our Home and every one of them will only switch to its Bluetooth output when the CEC protocol is disabled and I have no issue disabling it on any of the three LG TV’s, with either a Beam, or Arc, connected to the HDMI-2 port.
