Hi there, a really annoying problem: Got my Arc Ultra set up, eArc to HDMI, 2 Era 300 as rears and planning on buying a Sub 4 once the pain in my purse goes away.There are 2 content suppliers connected to the TV, an LG OLED65CS9LA: an Apple TV (latest model) and a PS5. Problem is with BOTH of those so it’s either the TV or the Arc. What happens is that after it was off for a few hours - like over the night - the system will only put out Stereo PCM. I have to manually change the sound mode in the TV settings (anything will work as long as I change it, auto, passthrough, no matter). All the other settings are correct, it’s just as if, when off for a few hours, the TV forgets to tell the Arc that it sends surround sound & me changing stuff will remind it.I read that it might be a problem with cheapo HDMI cables so I bought an expensive one and a super expensive one and nothing changed.I am very annoyed and would be extremely grateful for a solution.

I just factory reset the TV. Reluctantly because good settings and all.

Let’s see if it was worth it.
