LG WebOS (oled c1) audio out of sync

Plex Players
1

Hi, just installed my brand new LG Oled C1, i have done software update, installed the plex app.

All content i have tried the audio is out of sync.
Do anyone know of there is either a setting in TV or in the plex app I need to change?

I tried the same content on my nvidia shield on another TV and there everything works great.

OK, i think i solved it.
Sound Out (TV setting) was set to bluetooth and TV speakers.
I changed to only TV Speakers and then it looked good.
