I have a Sony AF8 (ARC not eARC) OLED TV, Sky Q and a Sonos Arc Ultra. The setup works flawlessly and plays Dolby 5.1 and Atmos from all TV apps and streaming apps on the Sky Q box.
However, when playing Sky channels either live or recorded, the sound frequently does not play when switching to a new channel when the Sky box is set to either DD or DD+. If I quickly flick to the next channel and back again a couple of times it might start working, or if I go into the Sky settings and flick back to Normal (PCM) and then back to DD or DD+ it sometimes works.
i have been onto each of Sonos, Sky and Sonos and each one claims it is not their problem and to check with the others!
I am beginning to think that I have spent £900 on a white elephant that only works when it feels like it. I am beyond frustrated with this. The retailer (John Lewis) is not interested and Sonos support have been of no use either, so hoping someone on the community can restore my faith in Sonos equipment
i also have a 1st gen Beam in another room and that works with the Sky Q no problem with this Sky Q/Sony OLED combo.
