I unpacked it, connected it to the TV via HDMI ARC, the TV was not Samsung, I chose the external speaker mode on the TV and that's it, no more settings, it connected on the first try and no dancing with a tambourine. The sound is bright, when something distracts from viewing and action happens in the film, you immediately want to look in the direction of the sound. The sound has become much better than on the TV, the dialogues are heard normally, they are no longer eaten up by the background.
