Hi, I recently got an Sony HTCT260H Soundbar, and I hooked it up via HDMI (ARC) and Optical audio to my Sony W900 TV. Originally when I hooked it, the soundbar would turn on when I turned on the TV and turn off when I turned off the TV. Also, the volume would change when I used any of the remotes. Now I'm not sure what happened but I have to turn on my soundbar separately and change volume by pressing the buttons on the soundbar (not even the soundbar remote works for volume). The remote still works to turn on the soundbar and change inputs. The soundbar doesn't automatically turn on or off with the TV like it used to, and volume through the remote doesn't work. MThis all happened within a day, and can anyone help me restore it to its original functions.
