You can try the "box" image here https://chewitt.libreelec.tv/t…LGX.arm-10.0.1-box.img.gz the dtb to set in uEnv.ini is "meson-sm1-h96-max.dtb" .. but this assumes your H96 Max is the same as the box I made the device-tree file (which is a gamble .. it's a clone). HBR audio should be working fine but video is in a rough state in the upstream kernel so CE is probably a better option.
Thanks a lot, will try and report back
