I shall have a check later today, although I don't have Dolby Atmos set up.Can any owner please comment on the playback of 4k hdr atmos mkv files from network devices such as a nas? Thanks
Edit - Via Plex DLNA it comes up saying that cannot play audio as it is not supported, whether this is because I do not have Atmos I have no idea. It won't even let me switch the the 5.1 DD audio track when the Atmos track is muxed in. Other than that, playback works flawlessly 4K video with AC3 5.1 and the HDR Optimiser works too.
