2023年3月10日 · Hi all, I purchased my C2 in December 2022 and initially loved it but very quickly an issue presented itself where there would be no audio from the TV and Shield Tv Pro to my Samsung Q930b over EARC Pro.

2023年11月4日 · My soundbar an JBL500 is connected with an HDMI 2.1 48Gbps cable to the eArc port HDMI2 of my LG C2 42. The audio keeps dropping every couple of minutes, and on the top right of my display it states "dolby atmos" as if the signal dropped and re-established.
