Creak-free indoor staircase -67

[kaked08]

Hello

We have a pine staircase with covered steps that's causing quite a racket. It clunks, knocks, and bangs more in the steps than creaks. It's as if every board is loose. What should we do here and what should we absolutely not do? Can we squeeze in wood glue, make openings, etc.

A bit of detective work 😃
