Question

Dolby atmos on Netflix - LG CX

Hello,

I have recently set up my LG OLED CX with Sonos Arc. I followed the below and getting Dolby Atmos showing on the Sonos app but still I don’t think it’s Atmos I am hearing. Any help would greatly appreciated. 
 

  1. 4K eARC HDMI connected to eARC port from tv to Sonos.
  2. tv internal sound turned off
  3. Digital audio output - pass-through 
  4. DTV audio setting - Auto
  5. eARC turned on

I am using it in a small room and did the initial setup for true play. With or without this setting Atmos is not fathomable. 
 

please suggest. 
 

cheers

Thanks mate. 
 

I watched that movie in different audio options. Definitely Atmos is whole lot different. I am just not sure if I am hearing the the full capability of it or not.

Do you think a room size matters? If I am seating Right against a wall at a distance of 3 meter/ 118 inches from Arc. No space behind me. But both side I have walls at 2 meters distances.
 

just want to try and optimise the experience. 
 

 

The Arc on its own cannot give you as good a surround effect from a true 5.0 surround with the rear speakers.

When I toggle the rear surrounds on and off, I can tell the big difference there.

Having said that, the sound stage of the Arc is pretty good, just not good enough IMHO.

This.  Surrounds (and a sub) will make things much better. IMHO, marketing any kind of stand alone soundbar as “immersive” will always be a stretch.

    Agreed.. I finally got my sub a couple of days ago… world of difference.. the lows that the arc chokes on are now transferred to the bass so now more power can be given the mods and highs of the arc.  Nice!

    So ideal is adding a sub and two rears ? $$$$$ all about then
