Issue
Whenever I start any video—whether it’s streaming apps, HDMI input, or a USB movie—the SC9S plays for a minute or two, then suddenly loses connection. Audio instantly falls back to the TV’s internal speakers, and the TV acts like the soundbar no longer exists on the eARC port. The soundbar display still shows “eARC” (sometimes flips to “OPT/ARC” for a second), but no sound.
Temporary Fix
The only thing that gets audio back is power-cycling the TV (standby isn’t enough; full reboot required). After that, the bar reconnects… until the next random dropout. This can happen multiple times during a single movie, which is a great way to kill the vibe.
What I’ve Tried
New HDMI 2.1-certified cable (same result, so original cable seems fine).
Disabled Quick Start+ and Simplink in the TV settings, then re-enabled.
Factory-reset both TV and soundbar.
Tested ARC instead of eARC—works, but no Atmos and same occasional dropout.
Plugged the soundbar into a different power outlet (in case of power spike).
Observed Patterns
Dropouts happen sooner with Dolby Atmos or DTS content, but even stereo YouTube videos eventually cut out.
No obvious heat buildup; bar is in open air, front facing.
Happens whether soundbar is wall-mounted or on its stand.
Questions for the Hive Mind
Anyone else seeing eARC instability with the SC9S on the UP77 series?
Could this be a handshake timing bug on the TV’s HDMI board?
Any hidden service-menu tweaks or firmware betas worth trying?
Should I just RMA the bar, or is the TV the real diva here?
Appreciate any insight—my couch and I thank you in advance!

On LG OLEDs. You go on and disable SIMPLINK. Fine. But everytime you turn on your HDMI device it enables itself back again. This happens because they have disables two key features that were present in previous OSs, as you can see clearly here
link hidden, please login to view (they even put screencaps of the menus where you see the missing options in the 23) These functions are Auto Power Sync and Auto Device Detection.
Man updates are supposed to add functionalities not the other way around. It's very annoying to turn on your TV and have your AVR turn on without you wanting to.
Anyone found a solution for this problem?

Hello,
I have purchased a new TV and I'm unable to login to the LG account. Whenever i try i get the error saying : The lg services country information could not be retrieved from the server. Image is attached !
I have registered the TV online on lg.com I tried resetting and rebooting the TV I tried the LG customer service which is pathetic and they just asked to exchange the TV with the retailer ( I don't know what customer service is smoking, if people start replacing TV for every software issue, it will be the end for LG Business) What else can be done?
Thanks,
Tushar
