New Sonos ARC with no sound from surrounds

Hi All,

I have just become the owner of a Sonos ARC which I have been looking forward to for a while. After setting up the ARC and having issues with my Sonos Play 1 surrounds I decided to hardwire my ARC and use the SonosNet configuration. 

I have an LG C9 and Apple TV 4K and have been using Netflix to tryout the Sonos ARC capabilities but for some reason the Sonos Play 1 surround speakers don’t seem to be in sync or on occasions don’t work. Or should I say sometimes for no reason vocals will move from the ARC to the Play 1’s… Sort of with a muffled effect. I just watched Formula 1 drive to survive on Netflix and the sound was everywhere even when a driver was doing an interview???

It’s as though the voice flips back and forth between the ARC and the surrounds, making it sound very unstable.

My ARC is connected to the eARC HDMI port and the LG C9 has eARC enabled and Passthrough configured???

I have also checked my Audio settings on the AppleTV.

Everything is running on the latest firmware’s including my iPhone when I configured the speakers.

I would love to know if anyone else is having this issue with the surround setup?


Or perhaps what I can do to resolve the issue.
