Microphone stops working and unwanted noise after connecting headset.

LAST EDIT: Closing the laptop lid and opening again while the mic is plugged fixes it till.

Edit 4:  I found a temporary solution, doing the following command with the headset plugged: #alsactl restore
Edit 5: Never mind, that doesn't actually work, it seems I actually fixed during the last boot somehow but not still able to find how.

I am on plasma 5 with alsa and pulseaudio. Laptop's microphone works fine, but when I plug in my headset the both microphones stops working and transmits unwanted noise instead.

    This problem appeared recently withing last two months, I don't remember any changes I did to my system that could be related.

    Unplugging the headset again doesn't fix it, I have to restart the laptop for internal microphone to work properly again.

    Restarting the laptop with the headset plugged in gives me a working microphone with no unwanted noise. Unplugging it and plug in again with this method also breaks it.

    ''pulseaudio -k'' doesn't fix it

Pavucontrol and alsamixer didn't help finding what is wrong.

Edit: The sound seems to changes every time this happens, but it is always one that goes up and down, from not audible to audible.

Edit 2: It seems to get stuck with the first audio it heard when I plugged the headset
Is there any reason in particular I am not getting any help here? If there is something wrong with my post please tell me, I won't learn if you don't.
Edit 3: After searching what i got in "edit 2" I found I have a feedback loop, I will try and see if searching that gets me anywhere.
