Squeaks and creaks
The sound is definitley coming from the floor. I think its the floor and baseboards rubbing. I never heard anything when the subfloor was bare or when the flooring was finished without the base. The noise came about when I put the baseboards and shoe molding back on. When I reinstalled them, I pushed them flat against the floor for a tight finish. So, once I noticed the noise I thought I may have made a mistake by not allowing for a small gap between the bottom of the base/shoe molding and top of the flooring. Like place a thin piece of cardboard between the two before nailing and then remove the cardboard. I don't know, I just wasn't sure if this was a common mistake I made. I guess not....
