Popping sound in headphones every second

[Troodle]

I keep getting these popping sounds in my headphones. The problem is that when I have both the jacks in the computer there's static and popping, but only if the microphone jack is in. When I only have the audio jack in there's no static and popping. I've had this problem with all of my headphones and I think there might be something wrong with the drivers.

I think there might be something wrong with the ground of the mic or mic port. Try using the rear jacks and if the problem is gone then its likely your cases front ports.

I use the rear jacks, not the front ones. I've tried the front jacks but they don't work.
