My Cloud ALPHA's Headphone Jack Isn't Working

[Lineland]

Today, after I woke up, I decided to play Alien Isolation with my Hyper X Cloud ALPHA's, and randomly, the audio went from my headphones to my monitor, then back into my headphones. It continued to do this, so I stopped and put my computer to sleep for about 5 minutes then turned it back on. It didn't do it for a while, and then when I started playing iw4x, it got way worse and more constant. It would just switch from monitor audio to headphones about 3 times a second, and now, only my microphone jack works. I know it's the part you plug into the PC because you don't need to have them plugged into the headphones for them to show up on device manager. Any help or advice?

Nevermind, I just plugged them in the back. I think my front headphone port os out.
