Microphone problems.
 

Hi there.

Lately im having problems with my microphone, whenever i'm testing it, it's either too loud, or too soft, even when i don't change anything.
I've noticed it when i've tested my other microphone in the past, and in one session it was too soft, and in the other session too loud.
It seems to happen at random, i diddn't had any problems with it in the past, though my other microphone had the same problem, my new one has it too.
Also, i can hear some static noise into the headset for about half a second, though this is rarely.
Can anyone help me please, i've plugged the microphone at the correct spot.

PS: It's a headset.
