According to this article from Sonos, the LG Magic Remote uses RF or Bluetooth rather than IR. But you should still be able to control the Ray’s volume with the remote by following the instructions in this article:

Thanks for the speedy reply. 

I'll give it a go! 

Hi, I just buy a SAmsung The Frame Tv (2020) 32 inch. I’m not sure about which soundbar is better for my tv. Sonos Ray or Beam Gen 2 ? Is dolby atmos compatible with my tv model?  I will add two sonos One for home cinema sound. We listen a lot of music and watch a lot of moovies. 

Thanks 

If you read the marketing literature, the Sonos Ray does not offer Atmos, it’s priced much lower in cost. 

The Beam Gen 2 allows an ARC/eARC connection to the TV which can provide Dolby Atmos, is slightly larger, and will likely sound a bit better with your new TV.
