Randomly if your near a minecart going up and down a rail it will sometimes glitch making the sound of it non-stop. You can turn off your sound of break the minecart and it will still go. The ONLY way to get it to stop is by quitting the game.
I expected that turning off the sound would stop it or quitting to title.
But instead i had to completely close minecraft.
This has happened twice at two different situations so I have no idea how to make it happen again.
