What's your current soundbar setup, and has a simple settings change ever completely transformed how it sounds?

We ask because we see it all the time in the store. People running perfectly good soundbars that just aren't set up properly. Wrong connection, wrong TV audio output, calibration never run. Small fixes that make a pretty big difference.

We've just put a video together on this if anyone's interested: https://youtu.be/P_526wtPlwo?si=EQ0eN2qKDVGektuU

But curious whether there's anything else people have stumbled across that we haven't covered. Drop your setup in the comments.
