I have a Beam, 2 Play1 wireless speakers, sub for my SONOS system. My TV is a Sony X940E Bravia and my 4K player is a Sony UBP X700. I’ve just discovered that unless I turn my audio output on my TV to PCM, most of my 4K discs will not play sound. Unfortunately playing PCM on my SONOS Beam is underwhelming. Streaming Netflix in Dolby 5.1 sounds better. I’m wondering if I have any options. Would it be better to purchase a different 4K player or dump SONOS since this has to do with their refusal to obtain DTS licenses. Is there a converter of some sort I can get? Thanks!
