Sorry whats AVR?
So i have an LG CX OLED - are you saying that the issue I am facing is actually to how the tv is transmitting the sound data? And the TV does not allow me to alter any sound settings when the soundbar is in use so there is nothing i can do about it?
I'm not very techy so if there is anything i can do to get dynamic range compression from my tv i need to know a product or means to change setting.
That is true. An AVR is an audio video receiver, but it is overkill to drive a sound bar. AVRs have dynamic compressors in various modes. TVs do not have dynamic compressors. The streams have high dynamic range, otherwise those of us with powerful HTs would be upset, since our systems can handle high dynamic range.
There might be a sound bar that has a dynamic compressor, but I don't follow that market. I know of no dynamic compressor that would interface between a TV and a sound bar.
If you really enjoy movie watching in the home, then investing in an AVR and some good smaller speakers and a small sub, would be a worthwhile, but not inconsiderable investment.
Sound bars are really just for watching news, and talk programs, and assume if you want to watch a movie you go to the cinema.
The fundamental decision facing you, is if your really want an improved home cinema experience? If the answer is yes, then you have to walk the walk,and pay the piper.
That is an individual decision for us all. All will have different expectations and means. But us our home theater brings us untold pleasures, as do our other two systems. If you own your home, then a neat in wall solution is possible. Our great room system takes up zero floor space. If you are a renter , then I understand your options are much more limited, in terms of elegant design minimizing use of floor space. Not being a techie, does not have to be a handicap, if you are willing to learn.
It seems to me you are looking for a better home entertainment experience, but you have some fundamental goals to set and decisions to make.
I know this is all easy for me to say, as I enjoy the challenge of elegant design, and the thrill of the build out.
