I was being shot at by a skeleton while I was in front of lava. The arrow missed me and went into the lava, which made a horrible sound that doesn't sound normal. The sound goes away after the arrow is burned. As far as I know at the moment this happens in snapshot 21w19a, I'm not sure if it happens in other versions. I did save, close the game, and relaunch it, but I noticed the sound persisted. I have created a small (unlisted) video on YouTube for you to see it in action.
