I have a Samsung QE65Q67RATXXC (that's what is says on tv's menu anyways) and a LG SL7Y Soundbar. I bought both of them a year ago and have been working great until now. Before, when I turned off TV, the soundbar also turns off, and when turning TV back on, the soundbar also starts and everything is OK. Now however, when I turn on the TV the soundbar turns on, BUT it goes straight to HDMI setting and there is no sound. Before it went straight to OPT/HDMI ARC and I had sound. Now it starts automatic on HDMI with no sound and I have to manually use the remote to change the setting on the soundbar to OPT..... Can anyone tell me what has happened and how to fix it?
