Strange computer audio issue with Razer Cortex

So I use cortex whenever I play FFXIV, but if I use YouTube or Spotify it'll come with these crackling noises and have no idea why. When I tab out they go away after a few secs and they also come even if the ffxiv sounds are in my headset but I unplug that so there's no sound from the game it still comes with the noises. Want to keep using cortex but it really annoys me
