I didn't say you made conclusions, I said the video itself is not 'conclusive' (With regards to the structural problem, it is assumed).
Throttle doesn't equal speed. And when speed is up, the camera picks it up as noise. When the jet goes slow, it is much more silent. At the times of your flaps deployment you were not going particularly fast. You hear this too when flying inside a sailplane, the faster you go, the more noisy it gets, and when you let speed drop, it gets silent ;)
From your own video, at 1:55 your were going pretty fast. Then you pulled up and turned, bleeding energy and speed in particular. THEN you deploy flaps at 2:05 when it's already much more silent. Notice as you pull up and bleed speed even further the mic goes super silent.
Then you retract flaps and speed up again... by 2:25 it gets noisy again just as it is to be expected.
