The Sony works excellent passing through DD 5.1
I am able to get 5.1 through the the Apple TV 4K, ATT U-VERSE cable box, and the PS4 while video gaming.
All peripherals are connected to the TV via HDMI while the Playbar uses optical out
I haven’t tried blu-ray movies on the ps4 yet.
The Sony is an excellent tv btw. Many feel it has a better picture than any oled because it is a FALD with a native 120-mhz panel.
This setup makes SONOS worth it. Turn your surrounds to full volume in the app for music and tv, and you will have a killer surround sound system as part of your multi-room audio system.
