I have the Samsung QE85Q95T 2020 TV Model no. QE85Q95TATXXU. The soundbar won't connect via HDMI eArc. I got a replacement soundbar still no joy. Tried the soundbar on an LG TV upstairs and works perfect. Also tried usual stuff like factory reset on Tv, tried using different cables and resetting soundbar. So it must be the TV or more likely the One Connect box. Had engineer out from Samsung approved retailer and the motherboard inside the One Connect box has been changed still won't recognise Bose 900 soundbar. Optical does not transmit Dolby Atmos. Any ideas as for last 3 weeks and counting I have a rather expensive ornament. I have read that on forums that there could be major problems with the Connect box on this model of TV ie 2020 Q95T
