I was originally responding to the comment about looking for surround sound options and was not trying to defend the sounds. Obviously, the info on the box is usually the best way to tell.

But as we discuss it, some use cases for the sound come to mind.

If the media is just a file on a hard drive or if the original packaging is lost or damaged, I might appreciate having the sound to indicate what settings to use on the receiver.

And honestly beyond all that… Who cares if somebody does like having the sound play every time? We all do weird shit.
