if you walk on a carpet the sound is not a wool sound (I guess how it's supposed to be) but the sound of the block below it

I don't think this is a bug as carpets have no hitbox, meaning the game thinks the player is walking on the material below.
...but, it would be better if this is fixed as it would make the builds using carpets more realistic.
