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

Indeed this is right👍

Ok this is a weird twist for you guys:

I’ve been enjoying my LG GX + Sonos surround (arc sub ones) during the day and just connect my Bose QC35 at night with no problem. For. Months. 

Well, until tonight.

I'm glad I found this thread but I’m sad there’s no answer! Again, it’s been working fine, no cec thing stealing and no disabling that on the tv options…

All I know is that tonight, I tried connecting my BT headphones while my show was already playing. It was a Netflix show in Dolby atmos.

oh gosh I’m sad and tired. I love the Sonos surround, but jeez.

edit: ok so turning eARC on and off made the problem disappear :) I’m back enjoying sound in my Bose and the Sonos surround is on. hope it helps someone!

Seriously Sonos?  Are you guys STILL ***** the bed on this topic?  I mean you have THOUSANDS of people stating the same problem FOR YEARS! and you still haven’t fixed the issue?

Give us a freaking answer instead of telling us to unplug our equipment!  That is NOT a solution!

Wow, just found this thread. I have the same issue with a sonos arc and an LG E9.

Very disappointed that Sonos didn’t fix the issue years after, that’s very poor for supposedly high end product.

You could just toggle ‘off’ ‘Simplink’ on the TV in your case - at least that’s all I have to do on my older C9. Then toggle it ‘on’ to restore connection to the HT on the HDMI-2 Arc/eARC port.

Following, same issue with LG C1 and Sonos ARC.  Wish I had known before the Sonos purchase. I would like some money back. We have some hearing issues here. I would like Atmos most of the time and would like my wife to be able to use bluetooth headphones when needed. 

I find even with eARC off and Simplink off if I accidentally touch the HDMI (ARC) sound out setting with the cursor it resets Bluetooth Device (Headphones) to ARC turning Simplink back on and hijacking the sound out to ARC. I can hardly scroll through the sound out settings, without Simplink and ARC turning back on. Anyways I just scroll carefully in the direction that avoids HDMI (ARC).  Pretty klugey. 

Kinda lazy of Sonos not to fix this, they sure worked hard enough on the rest of it.  If they were clever they’d launch their own bluetooth headphones that would integrate with their products and work, a line extension if you will to make a buck. 

Hi all, 

I bought a pair of Sony xm4 headphones yesterday and suffered the same issue, which had me thinking overnight. 

I think I have sussed out a work around to stop whichever Sonos sound bar cutting in, after a couple of seconds of Bluetooth headphone sound. Forgive me if this is elsewhere on the forum and I am repeating something that has long since been known. I just haven't read all of the stuff that's been posted but clearly from what I have read, it has remained an issue for some, as until this morning it was for me. 

Firstly, I own a ‘18 LG 65 wallpaper TV with which I found that switching off the Simplink hdmi cec toggle in All settings/general, then selecting Bluetooth device in the usual way the headset should connect and remain so. To revert to the soundbar turn Simplink back on. 

However and secondly, this did not work with my ‘21 LG 77 C1 set. I remembered from the initial TV set up, that there was a eArc toggle buried in settings and this turned out to be the key. 

Therefore;

All settings (3 vertical dots)/General/devices/hdmi setting, then toggle Simplink HDMI CEC to off. Then still in All Settings go to Sound/Advanced, scroll down to eArc and toggle off. 

Come out of ‘all settings’ then change sound source to Bluetooth and connect device in normal way. When you want to revert, first turn Simplink back on  and then toggle eArc to 'on’ (it won't work the other way around because eArc is greyed out. 
 

This is far from ideal and still requires some fannying about with settings but at least it's better than physically disconnecting power or hdmi cables which in my case and no doubt many, can be very awkward and in any case, I understand that  hdmi is not supposed to be routinely plugged in and out.
 

I haven't lived with doing this yet and it maybe that Simplink turns itself back on when the TV is turned on and off (the eArc will not btw) but hope this helps someone out. 

Amazed this is still an issue! 

Does anyone know if beam v2 is the same, if so I won't even bother looking at upgrading. 

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?
