Recently my gf bought me an Alienware headset, 310H I believe. I just got it a few days ago and it was fine at picking up my voice but since then it has gotten to the point where it's not able to pick up my voice at all. I use it with my PS4 so I just plug it into the controller. From the audio settings and in-game testing it's apparent it can't pick anything up. Can someone help me troubleshoot this please?

(apologies if this is the wrong category)
