Since my lg-oled65c9pla auto-updated to WebOS 5.5, there is a new bug.
The TV is connected to my Cambridge Audio Evo 75 amplifier over ARC - on powering the TV, it has always started up the amp, and switched it to use audio, instead of the appalling TV speakers. The whole setup has worked flawlessly for 5 years, but since WebOS 5.5, the amplifier starts, but is left in a muted state, and using the un-mute or volume controls on the TV remote makes no difference to turning on audio. The only way to get audio to play though my amp a speakers is to turn the amp's volume dial or press a volume button on the a amp's remote - this then unmutes the TV and audio is back.
There is no setting I can find in the TV that relates to whether the ARC channel starts muted or not...
No software has changed in my amp. This is an annoying new bug in the TV software, I assume down to some CEC changes.

When connected to the TV with a laptop, black boxes appear on the screen. We tried this with many computers. The result is the same. What can I do.

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!

Question
S SS
I have an LG OLED65B7A B7A Series 65" OLED 4K HDR Smart TV.
Is there a way to always display the time?
Just a little time display like in the lower-right or elsewhere ?
I want to see the time whenever, or whatever, I'm watching TV.
Its odd that in settings I can set both the time and date, but there does not seem to be a way to display either!
Thanks for any help!
