Are there any tricky alternate meanings of laut?

Why not use an die Haustür here?

an die is accusative (motion toward). The sentence states a location, so you use dative: an der Haustür. Use an die Haustür with motion: Er geht an die Haustür.

Do I have to use die? What about eine?

• die points to a specific, known bell (normal when there’s one at that door).
• eine introduces a new/unspecified bell and sounds odd without context: Eine Klingel an der Haustür ist laut. More natural if contrasting multiple bells: An diesem Haus ist eine Klingel an der Haustür laut, die andere ist leise.

I’ve seen Haustüre—is that correct?
