Hi
Until recently I was a happy PS3 user connected to a Sonos system (playbar, sub, plus two 1's) via optical. Surround sound worked perfectly for PS-store movies, Blu-ray, Netflix and Delete repeated word
Recently upgraded to a PS4 slim, and did read the fine print where they omitted the optical out! (Grr...!). Anyway, as per common advice I purchased a HDMI > Optical extractor to connect audio from PS4 to Sonos via optical Dolby 5.1. This works fine for Netflix and games. However both PS-store movies and Blu-ray are only playing in Stereo. If everything was stereo I could understand it, but Netfilx works, Games work??? Why does PS-store movies and Blu-ray not play in 5.1?? Anyone have any ideas?
