I know this space is usually about older hardware, but I wonder if someone could help me out and let me know if this is normal for an Xbox controller. Is it a busted d-pad?

Left, right, and down all sound sharper and slightly louder

Up is softer, distinct from others. Maybe ever so slightly softer to touch than other directions, but not much.

I've recorded a little video showing the difference in sound: https://vimeo.com/645239563
