This is my last word as this is getting monotonous going back and forth. You're happy streaming with your LG then that's fine with me.
Despite my audio issues with my LG OLED, I have sampled some movie titles and they look better streaming from my ATV4K unit then if I stream them from Vudu or...
I was being facetious, I'm sure I would figure it out if I didn't have Roku and Apple units. However, I have those units so I have no motivation to figure out my audio issues using just my LG OLED displays.
