Reoccurring drywall crack above door

I have a split level house, circa 1958, with foundations not monolithic. Cracks above the doorway beside stairway to upstairs is cracking no matter how its patched. I was wondering- If I take out drywall and put up 1/2" AC plywood in one piece above doorway, screwing onto studs, except directly above doorway corners, finish plywood with drywall,- if that would keep the cracks from coming back. Another idea is to cut bottom wall plate loose from floor and let float on spikes like I've heard done where moving floors are a problem. Any tried and proven answers out there?

Howdy a photo would help
Consider a painters trick white silicone caulk in the crack then paint . it gives where as drywall does not. Another idea is to float the wall not nailing into the studs the last 7" of the wall so if deflection the wall does not crack....
There is a spray can of crack repair that woks well on some cracks available at big box stores and paint outlets ...

Take a razor knife and cut where the crack ends after you are finished it should look like a T. I had the same problem in a house I was working on and the crack did not come back. The cut does not have to be deep.
