I was about to report the same thing.
Though the difference in my version is I can kinda hear some very faint low grade humming when I hold the “A” button but yeah still barely any sound at all out of it especially when compared to the very loud and clear and I’m sure correct sounding Switch version of the game.
Also the similar looking standing stones in the cave for the music/chime puzzle on the Ginger Island 1.5 expansion also don’t produce sound.
