Microphone input is output via speaker as output?

Following problem:

My laptop is since today the microphone input as output directly from the speakers again.

That My microphone is inadvertently put on reception all the time and no matter what I do, any key I press or slide with my chair or a mouse click is picked up by the microphone and immediately played back with a strange noise and echo crack on the laptop speakers, Have tried everything possible, but as soon as I boot up the laptop, I'm subsided by dreadful cracking. Have now disabled the internal microphone for now. Connecting a headset via the microphone input does not cause any problems, but in principle it also has two different inputs: jack and standard microphone, which you can use, for example. Used for Cortana.

Go into the sound settings of Windows, click there on the device properties of your microphone.

then on the right side (in Windows 10) go to additional properties. Then the sound dialog opens from the control panel.

there may not be a tick when listening to "use as source"

that should hopefully fix your problem.

Thank you. The problem is unfortunately that I find this selection field interception nowhere. I already thought that there's something like that. But I just do not find this selection rider. How do I get there with Windows 10?

But that is exactly the solution to this problem. We have been several times.

Settings - Sound - Microphone on device settings - right "call additional device settings" - then opens a system control dialog to the Mic. There to listen and remove the hook at "use as a playback device".

Thanks, I will try it out tomorrow. If it does not work / I'm too stupid I sign up again. Good night and nice sunday!

Well, first of all, there's Saturday. Even if your nick is already Monday again.

I'm curious if my tip has helped.
