Final post for now - another month passes, no further issues since I set up the bar again without Alexa.
I can see other folks have other experiences, but this seems to be liveable-with for me, even if it shoots itself tonight - six weeks on a reset is tedious, but not awful. Still, vastly disappointed that Samsung cares so little about what is actually very expensive and supposedly transparent consumer hardware - that and the awful TV interface really makes me pause for future purchases.
