Check the seal on your top-joint with a vacuum test as described below.
Hold the top-joint in your left hand and close all the keys with normal pressure. I dampen my fingers first.
Seal the bottom of the joint with a finger of your right-hand, and suck all the air out of the reed-well, ending up by sealing the vacuum inside with your lower lip.
If the vacuum lasts for less than 8 seconds it ain't good enough to play.
[On a well-adjusted instrument if you finger D and press Octave-2 you get the top A harmonic - so this may point to a sealing problem perhaps around the reed-well or the top-octave insert. However, any leak at an appropriate position to dampen the fundamental and 1st harmonic can cause the same effect]
