I bought a new LG OLED C2 (OLED65C2PUA, 2022) and new Sonos products including the Arc+Sub+One SLs, and a Beam (Gen 2) for another room. The firmware for all the products have been updated to the latest version.
However, I noticed that there would not be any sound with eARC enabled, and while there would be sound with eARC disabled, it would skip every other second. This happens whether with the Arc or Beam. The only time it would not skip is when I turn on PCM, but PCM has no Dolby Atmos or surround sound capability.
I have followed every advice I could find, including ensuring that SIMPLINK is enabled, ensuring passthrough is enabled, disconnecting and reconnecting the sound bar (I don’t have any other HDMI devices), and even factory-resetting the TV.
I’m at the point where I think the TV is the problem, and I realize that the community’s experience with LG TVs have been spotty. I’m a step away from initiating a return of the TV to Amazon. But before that, has anyone tried anything else that worked?
