I have an LG 4K TV (model 65UF850V) with webOS 2.0 and Mezzmo app on my PC that is up-to-date.
Everything works well when i play 1080p files, but when i try to play 2160p files, they do not work.
The files are .mkv with HEVC (h265) video encoding and AAC audio. I checked the LGs website and it says those codecs are supported, but when i try to play the files, the TV outputs a message saying that the file is outputing only video but not audio.
In the Mezzmo settings i tried different profiles (2017 LG and LG UHD) and i also tried to disable transcoding.
Thank you for your help.
