I just purchased a new LG C1 65 and Sonos arc SL from Costco. And I hooked the Sonos arc with the original HDMI cable to LG C1 HDMI-4 (all four HDMI ports support ARC/eARC). But somehow Sonos app shows ‘Can not connect to LG speaker’. I have turn on the following options for LG C1:

  1. Sound out: HDMI ARC
  2. HDMI input audio format: Bitstream
  3. Digital sound out: pass through
  4. eARC: Enabled 
  5. Simplink (CEC): On

Not familiar with this TV but according to https://techparasol.com/lg-c1-smart-tv/ only HDMI 2 could be (e)ARC: “The LG C1 has eARC on HDMI 2 and is able to pass a Dolby Atmos signal via TrueHD via eARC..”

I’ve not come across any TV’s with more than one audio return channel on its HDMI ports - my thoughts too are to switch the Arc to HDMI-2, which is normally the ARC port for LG TV’s.

All four HDMI ports do not support ARC/eARC, only HDMI 2.  From the specs page for that TV:

  • HDMI Audio Return Channel (ARC)      eARC (HDMI 2)
