Likewise. I used to mostly buy Samsung. My latest TV was an LG OLED. Not only I find webOS infinitely more usable than anything I've seen on Samsung TVs, but the image quality is excellent and even the built-in speakers are acceptable after I disabled the crappy AI-assisted stuff that makes it all sound like it's reverberating in a dumpster.
I have a soundbar since before I bought this TV. It does sound better than the built-in speakers but it started acting up recently (volume going up or down every minute or so for no reason). I tried resetting it, re-flashing it, etc but nothing worked. It doesn't happen always either and I haven't figured out a pattern.
I decided to stop using it and started looking for better soundbars. Eventually I will get a 5.1 or 7.1 system but for the moment the TV speakers are more than acceptable for everything I do - movies, TV, games -- I don't use the TV for music. For now though, the speakers are sufficient. They don't sound too bad. To be fair, there's not much reason they should since there's enough space where they're mounted for decent sized cans.
