Hi all apologies if this has already been covered but i've started to watch Homecoming the 4k version. It looks ok but the audio is displayed as PCM when the program info states 5.1? How can i ensure it plays DD5.1? The settings under audio just give English as an option. Netflix progs play fine in the correct audio and so do the games i play so not sure i need to do anything with the Xbox or my AV Receiver. Any help appreciated.
