I recently purchased a Playbar and 2 One speakers. I also listen to tv through headphones, and use a J-Tech digital to analog decoder with optical pass through, to split the Optical signal for both headphones and Playbar. Here is my question- setting my Xfinity X1 remote sound settings to Auto-detect for Dolby Digital seems tp produce the best surround sound for tv programming. However, when playing Homeland(On Demand) from Showtime, the center channel sound(including most dialogue) disappeared. I had to switch the Xfinity settings to stereo to retrieve the dialogue, which then limits the surround sound. Other tv shows don't seem to have this issue. Any ideas?
