People having a right go at you here in the comments. If it works for you, then it works for you. If not, then your dissatisfaction is part of your education on the matter. My first soundbar, a Hisense, was initially satisfactory but as time went on, I was increasingly dissatisfied to the point where I got a Q800d and I've been happy ever since Sometimes the first time works out, sometimes you need to get burnt so that you learn

My Q800D is affected by this. It powers on and says it's connecting to HDMI ARC over and over again. It then stops and is unresponsive to the controls on the soundbar and the remote with no audio coming from it.. Spoke to Samsung, they want me to take it to a repair shop, not ideal having to haul a massive soundbar around..

Sony HT-A9. Phenomenal virtual surround sound. Even my cats look up at a sound from a speaker that doesn't exist.

Well of course the Sony doesn’t sound good. You have it fully blocked by the tv and encased in a tv tomb essentially. Is say return everything and just get the Sonos beam 2
