[MDL ED] Custom door - sounds not working as they should

[The chaser]

Wait a sec, two hinges aren't necessary

The only thing about the meshes:

You must have:

The door mesh (the door itself)
The door hinges (THIS IS ONLY ONE MESH) //You can Join several meshes in Object Mode, at the left bar.
In the model editor, create three shapes: One that fits the door itself, and one for each hinge, but ATTENTION!

With the door shape create a body, attach it, etc-With the hinges, choose the two shapes and make a body: Then relate the body to the hinges mesh.
In the joint, the parent is the static body of the hinges, and the child is the door itself.

Note that this is what I do when I want to make doors, I guess one of these should work. In extreme case, you can give me your model and I'll fix it for you, I've done it several times
