MacBook Pro Microphone Cuts Out

I bought a MacBook Pro in early December and have been having issues with calls. Whether I'm using FaceTime, Discord, or Zoom, my mic sometimes cuts out and people are constantly asking me to repeat myself. I have tried using different headphones and changing mic sensitivity in certain apps, but this does not solve the problem. I have not had this problem on any other device. Apple support recommended that I make sure I was using update Catalina, so I updated, but it solved nothing. Is this a common problem with the MacBook Pro? If so, how do I fix it? Or do I need to use my Apple Care to get a new computer?
