Lowered pitch for recording

I apologize if this is not a new topic. I searched first and found a thread relating to the problem, but didn’t see any replies that supplied an answer. My issue is that my recording track starts at a lower pitch than the main track with a “whoop whoop whoop” sound. I have uninstalled and reinstalled and reset with not luck. I’ve recorded successfully as recently as November 2017. This is my first attempt since then, but can’t get it fixed based on any of the answers I find on google or in this forum.
