I have a FM45C/ZA sound bar connected to UN70KU630D TV with an ARC HDMI cable. It has worked fine for years being controlled by my Xfinity TV remote. The soundbar screen shows an TV ARC connection. In the last week the sound has switched back to the TV, sometimes when I’ve paused a stream or changed inputs. It has even reverted spontaneously without me touching any button at all. Some change must have been introduced by Samsung which caused this anomaly to happen. Please look into this matter and fix it.
