Arc SL: LG C2 Keeps switching back to Arc SL when trying to switch to other Sound Outputs like TV speakers

@GuitarSuperstar Found it at the bottom of the Advanced section of the sound menu.  Worked when I tried it last night.  Will see if it works in the future.  Still annoying to have to flip a separate option on and off but better than unplugging the Arc.

@GuitarSuperstar Back again.  eARC on or off apparently doesn’t make a difference.  Really would love Sonos or LG to fix this.

So I got the sequence to work for my LG C1

1. Go to Settings > All Settings > Sound > Advanced Settings and disable eARC Support
2. Next go to Settings > All Settings > General > Devices > HDMI Settings and disable SIMPLINK.

once you do this you can keep using TV Speakers or any other speakers including Sonos Arc. Make note that as soon as you select HDMI(ARC) device again, SIMPLINK will be auto enabled

Thanks, yes it works with my LG G3 and Sonos Arc also.

but it is really anoying to have to go back and disable those two settings every time I want tomlisten to Bluetooth headphones. Isn’t there any better way or fix for this? When Bluetooth is selected on the LG TV it should switch those two settings of automatically, for example…

This works, but I have problems “reversing” it when I want to use eARC + Sonos Arc again.  All the settings are done correctly (SIMPLINK does turn back on when you pick HDMI ARC wired input on LG, then you can enable eARC separately), but no sound comes out and the magic remote can’t control the Arc.  Only fix I found was to unplug/replug Arc.

How about adding an HDMI switch so you could click a button to connect/disconnect the TV and Arc? Just leave the second port unconnected.

Oof.  I mean, that might “work” but a) this should not require additional hardware, it should just function correctly and switch inputs and b) if I’m going to get up I could just disconnect/reconnect the Arc which also “works”.  I don’t know if this is Sonos’ fault or LG but they need to get their * together.

Additionally, you can set SIMPLINK (HDMI-CEC) as a shortcut to the quick settings menu.

Hi,

I opened a ticket at LG. This is the feedback I received (translated via google from german to english):

My request:

Ladies and Gentlemen

I recently purchased an LG TV "OLED65C39LC". I use Simplink and have connected the TV to a Sonos ARC. Unfortunately, it is no longer possible to change the audio settings so that you can either use the TV's speakers or use a headset connected to the TV via Bluetooth.
 

I would like to continue to use the CEC function in conjunction with a Sonos ARC, as I normally use the Sonos ARC for audio output. In the evening, however, I would prefer to use a headset that is connected to the LG TV via Bluetooth.
 

Problem: Every time I switch to audio output “headset”, the TV resets the settings back to HDMI ARC (Sonos ARC) after 2-3 seconds. The problem has already been described by people in various forums and has existed for more than 3 years. I find it disappointing that a product like the OLED65C39LC also has this problem - even considering the very high price.
 

Deactivating the Simplink function is not a solution either! I don't understand why LG hasn't implemented the feature so that the audio settings that you set manually don't remain permanently configured.
 

I hope that LG finds a solution here and offers it to us customers.

The Feedback:

Dear Mr. *****,

Thank you very much for contacting LG Electronics Deutschland GmbH.
- Due to the CEC control, the HDMI-ARC connection is always prioritized and functions normally. I can't offer any solution other than interrupting HDMI.
