eARC on the C1 will not passthrough any DTS, DTS:X, etc. audio - only Dolby flavors. Also there are numerous forum reports that eARC on the LG C1 will not dependably passthrough multi-channel LPCM. There's even a change.org petition asking LG to fix LPCM passthrough. (LG is not the only TV brand whose eARC will not passthrough LPCM.)Does anyone is using Jbl 9.1 soundbar with LG C1, please share any issues or good things about these two devices working toghter, how is the dolby atmos using the eARC output from the Lg C1 oled, I'm ready to buy these two guys but need some feedbacks, please make a comment.
