Just got a new Sony x90h, and i tried connecting my yamaha ysp 2500 soundbar to the tv using the ARC port with hdmi and it doesnt work! Work first time during setup then after switch off tv and switch on again, the soundbar stops responding to the tv. Tested HDMI cable and soundbar on previous samsung tv with same hdmi cable and it works (switch on tv, soundbar switch on, etc). Reset the tv 2 times dy, always only works at the initial boot after switch off tv and switch on again stops working. Unplug plug back in no response. Also bought hdmi 2.1 port just to test but still no luck. Anyone got experience? Or must claim warranty
