Sonos Arc Issue: LG OLEDC9 & AppleTV4K.

Help needed as configured with very common equipment that will affect many existing and potential future customers.  
 

Two main problems with Sonos Arc:

1. No Voices watching movies on Disney+ or Amazon Prime via AppleTV 4K
2. No Dolby Atmos

Equipment:

LG OLED C9 (Updated Software  Version: 04.80.03)

AppleTV 4K

Sonos Arc

Connection (both Arc and AppleTV to the LGC9):

HDMI 1 port: AppleTV via Zeskit 8K Ultra HDMI cable (with eARC and Ethernet)

HDMI2 port: (ARC connection port for LGC9) Sonos Arc via same brand and model cable above 

LG TV set to:

HDMI ARC
→ Digital Sound Out (Pass Through) 

→ eARC (On)

HDMI Input Audio Format → Bitstream for all HDMI Ports

I spent a lot of money on the latest and greatest equipment and very surprised to see the Sonos Arc not working correctly.  One Apple thread said problem with Sonos Arc as only 1 HDMI port on the Arc.

Coming here for experts advice   
 

Again, the equipment I have is pretty common and will affect many existing and potential future customers.
