In the other thread I started I mentioned BB-8 made a noise not present in the BD.
I stick by this.
Around 50% of the cams have that noise, and it was definitely there when I saw it in the theater 10 times, every time. Whether it was an audio error for some prints or some versions had it and some didn’t due to differing audio tracks, I don’t know.
All I know is that the BD does not have this and there are cams that do.
Take it as you will, but that noise BB-8 makes during the shot sounds exactly like a noise BB-8 would make, not an audio glitch.
