I’ve upgraded my tv and so have changed Sonos soundbar to HDMI e-arc with ir signal to use Samsung tv remote.
issue is that I have a Sonos play as single rear speaker grouped to use sometimes for movies etc. with optical setup the sync was perfect. With hdmi setup I have the 75ms delay that sounds terrible with soundbar 10 foot in front and single Sonos play 3 feet behind me.
help please
