How to adjust the "squeaking" / "howling" PVC windows?

Good morning

The topic may seem simple, but I must admit that I have big problems coping with this problem. I moved into a new apartment and a PVC window howls at the desk. I turn on the sound. It goes crazy all day long. : /

Of course, under the slogan window adjustment there are various movies and tutorials, but none leads directly to the issue of this squeak / howl, and an attempt to adjust the side clamps did not bring any result. I also tried to seal the window in accordance with online tips, but the same -
nothing happened. I don't know where to start and what it means "you have to figure it out". I will be grateful for specific information. Where does it come from, what to do with it and how to proceed.

I also add a picture of the window. although I don't know if it will change anything, except that it is a standard PVC window.

I write immediately - I do not have warranty for these windows, I do not have the option to force the owner of the exchange; I am not looking for alternative solutions in the style of knock / wall - I am interested in whether this problem can be solved, and if so, how.

Thank you for the advice and best regards

Simple, buddy, look at the window like the picture on the bottom right you have a hinge. By lifting the white cap (cover) of the hinge you will reveal the hinge under the hinge you have the key (hexagon) and here you have pdf how to do it

I don't know anything about it, but the windows (usually at the bottom) had such ventilation holes covered with such caps. Sometimes wind doesn't "play" in those holes (if any) in your windows.

I did such a regulation at home, but due to the fact that the wing was slightly "dropped". It could be seen and the level confirmed.
Before attempting such adjustment, check that the sash is properly seated. Because you will change his position.

On the bottom right is the window adjustment in the up / down axis. The downforce there is maximum, it cannot be tightened any further, and any attempts to adjust up and down do not change the matter at all. I fully adjusted the screw in both directions. It is buzzing.

I also tried to seal the holes - from the outside and from the inside. Unsuccessfully.

This sound from the file is extremely intense. Something must generate it. Is there, for example, an antenna dish hanging near the window and the blowing wind "rolling" through it, or the cables causing no sound? When the wind changes direction is it just as loud?

These openings at the bottom of the window from the outside are used to drain water among others. When the window is tilted like a window and rain is falling, the water flows into the frames and just flows out through these holes.

Smaller with what they are used for, but when the wind "blows" into it at the right angle, it can "whistle".

OK, it will probably be funny, but ...

I tried all possible options by adjusting element by element, moving them in different combinations and nothing. Then, using carpentry clamps, I tried to constrain various points of the window on the wardrobe and check which part of it may not adhere exactly - nothing. I was looking for small places where the wind could blow and move these tissues ... Then I tried different versions of seals and tapes - also nothing. And finally, on the advice of Waldemar from Kashubia, I began to look in other places. And you know what? I feel very stupid, but it turned out that the sound generates the clearance of leaky silicone below the window - in the place where the window connects with the door frame. I covered with adhesive tape and stopped whistling. : /



I don't know what to say, stupid thing. If someone wants to add something, I invite you and tomorrow I close the topic as solved.

So just a window wrong, poorly seated in the window opening, the window itself is not guilty, in a word, simply "partacka work" during assembly

OK, everything works and explained in the previous post, thanks for help, I leave for posterity.
