Hello,
there is a problem with the EDID reported by the LG CX, with the current firmware 03.21.18, related to the audio formats exposed in the HDMI EDID info.
The TV states support for only 2 channels, then disabling multichannel LPCM via eARC with some eARC connected equipment.
LG C9 was affected by the same issue and LG released a firmware update where the number of channels for LPCM reported in the HDMI EDID info was upgraded from 2 to 9.
Would please LG make a firmare update fixing this for the LG CX too?
Regards,
Dani
