And although I last had a microphone on my laptop and there always comes a message microphone input… And I clicked on don't show again and selected microphones. But if I want to put my headphones in now I can't hear anything about them, maybe who can help me?
Yes, if you have a combo socket on your laptop (headphone and microphone input combined) you have to select that it is a headset when the message appears again.
If you have separate headphone and microphone inputs on your laptop, you need such an adapter https://www.amazon.de/...075WTK8X5/
Yes, but I didn't press show anymore
Then have a look in the control panel.
Under: Hardware and Sound / Asus Smart Gesture (at Asus, (simply the device manufacturer)) and then click on the small headphone input and click on (always show) in the window.
