I purchased a TCL Alto 7 sound bar because I wanted to match brand names with my 49inch TCL Roku TV. Two days after installing the Alto 7, my HDMI 2 and HDMI 3 inputs stopped working. I can’t connect anything. I tried a factory reset and the problem is still there. The soundbar works with arc and CEC but the HDMI 2 and HDMI 3 are not responding to anything I plug in. I think the Soundbar ruined my HDMI ports.
