Hello Johnny. We need much more information about your system and setup; otherwise this would be pure guesswork.
Let us know about the system you are using, including OS, storage, RAM, etc. Also, go into Premiere Pro preferences and check the audio hardware and audio settings. Let us know what those are.
Many folks will place a lot of the basic system info in their signature, so you don't have to repeatedly share it when you want some tech assistance. Gather up your info and post, and we'll see if we can help you.
