I tried to play the LG HDR UHD Demo File, which is available here: http://4kmedia.org/lg-new-york-hdr-uhd-4k-demo/
Playing the Video is possible but there was no sound. I checked a couple of options but wasn’t able to hear the sound of that video.
I tried the same with another product starting with “M” on my ATV and it worked perfect: HDR picture and sound.
Does someone has an idea why there is no sound with Infuse?
