Hi I’ve a Samsung tv ue55f6670 and I’m running a sonos soundbar, sub and 2 play 1s for my surround but for the life of me I can’t get it going Dolby digital even though Samsung say it’s a dd compatible !! I’ve spoken to sonos and they said once I added my play 1s to complete the surround it should automatically go dd but it won’t , the tv is on pcm and only other option I’ve got is neo 5:2 , the option for dd is there on the tv but in grey so cant highlight it ! Just spoke to Samsung and the person reckons my sonos , xboxone and PS4 isn’t obviously compatible on my tv wtf ??? I have seen on here about other methods ie optical switches but sonos didn’t recommend this ! Can anybody help ?
