Speaker of laptop is spinning - very high, unpleasant in the ears sound with crackling noise?

In addition, one hears between the many crackling noises again and again a loud bang, as one hears him about in war games when firing…

I have watched a video on Youtube (old "bet-that" show), in the middle of the video, a sound has suddenly become louder, at first I thought that in the TV studio, the sound system got a feedback or feedback.

But when I closed the tab, the sound was still there. When I turn the sound off, it's gone too. But when I turn up the volume, then the sound starts very softly, gets louder and has reached its full volume after 5 seconds.

First you hear a noise, then an extremely high tone, where you do not dare to make it higher than 65%, because from 50% volume start the crackling noises, which are getting worse. This high tone swells quite, very slightly, up and down, much as if you played a note on the violin, while the hand with which you press down the strings wobbles a bit.

Is the speaker broken?

How does this sound over headphones?

As described by you, the speaker can't help it; It does not become louder and quieter, and whistling is only transmitted by him.

Try out!

Connect the speaker to another device.

Then you can tell if it works, ev. A loose contact is the problem or laptop is to blame.

Edit: The question has, I believe, answered itself. After I deactivated the microphone, everything is in perfect order again. Then that was probably a feedback, because if I did not look at anything, I did not have the problem either.

And the laptop without speakers? Does the sound still work?

It was only the microphone permanently, so there was a feedback. After I turned off the microphone, the problem was gone: -D.
