Sonos ARC & LG TV constaly not working eARC

Question

Hello forum,

I’m going crazy trying to solve the issues of the Sonos Arc constantly disconnecting from the TV eARC every power cycle and reverting to the internal speakers.

Have tried every possible combination, enable, and disable without luck.

Auto Power Cycle (ON and OFF)
Auto Device Detection (ON and OFF)
SIMPLINK (HDMI-CEC; ON)
QuickStart+ for LG (ON and OFF)
HDMI Ultra Deep Color (Enable and Disable)
Instant Game Response (Enable and Disable)
All HDMI Cables Tested
HDMI cables connected to TV no luck
HDMI cables disconnected except Sonos no luck
HDMI-CEC setup only for the Sonos ARC
eARC enabled

I’m running out of options to test, is very disappointing and frustrating that a soundbar of 1000€ + 800€ sub is constantly required to setup every day to enjoy.

Have run a diagnostic 303498386.

System version 14.19 and LG TV updated to lasted software.(65NANO866)

If anyone can help will be much appreciated.

Hi @fernando21Welcome to the Sonos Community!Unfortunately, all I can see is the Arc attempting CEC initiation every few seconds, but very little beyond that. As there are no other devices connected, however, that narrows things down a lot.As you didn’t specifically mention it, I have to ask: did you try unplugging your TV from power for a couple of minutes? A hard reboot of the TV can often fix things that just going to standby won’t affect.I hope this helps.
