Our Sony 56" has perfectly played Netflix via 2 sonos S1' and playstation. Until tonight. We went down the list of things that ARE working. TV surround sound: check. Goodgle via tv. Sound is perfect, Apple Music controlled S1's. (3 more around the house). I loaded all 5 as a "group" tonight and they played perfectly. Back to Sony TV control. We get a good looking picture but no sound. It worked last night. i doubt our Snarky Sneaky friends aren't smart enough to futst with it. Did asssigning (controlling) all 5 sonos to a group from my iPad do something bad? Seems to be undone now but still no sound.
