Astro A40 TR issues

Out of nowhere I put the headset on to play a game, and the mic won’t work, it sounds like it’s crackling and it’s as if the cord that connects the headset to the mix amp spontaneously broke, have to move the jacks around to try to get it to work but it won’t. One minute it was perfectly fine, now it’s not. Do I just need to buy a new cord?
