I'm having issues with my new QN85 when I enable Atmos compatibility in the menu I get either no audio on the back speakers (such as in YouTube) or I get some audio but with a lot of crackling. I tried with eArc Auto and off (my soundbar doesn't support eArc). I confirmed on the soundbar that it is getting Atmos signal it's a Vizio SB56514. Also there is a lot of audio delay.
It's the same issue no matter the inputs I use (PS5 connected to TV, Roku connected to TV and built in apps.) .
All my firmware are up to date. Any ideas? Thanks!
