After the most recent LG CX upgrade to 4.30.55 I no longer get Atmos (or Dolby Digital 5.1) on my Arc. I’m using an Apple TV 4K for all streaming, not the apps on the tv. E-arc is enabled and TV is set to pass through. No physical or settings were changed from before the software update. Anyone having the same problem or have a fix?

I would try unplugging the the TV, Arc, and Apple TV from power for a couple of minutes and check the audio settings on the Apple TV.
