I need advice on how to fix my mic issues

Hey there,

I've been having a problem with my mic. Whenever I plug it in to my controller, no audio comes through. I check to see if my headset is connected, and it isn't, despite the fact that I've plugged it firmly into the headphone jack. In the time after this
first happened I've gotten a new mic, but the problem persisted. I decided that it must be a controller problem, so I switched controllers. My mic worked fine for about 5 months until the problem arose again.

Does anyone know what the problem is and how to fix it?

:)
