Distorted Audio

[elijahmusicboy]

I recently decided to buy a years worth of monthly payments of Pro Tools 2020 to make my life easier for recording, mixing and producing. I was super psyched about it until I realized that the sound coming out of pro tools was very distorted and I made sure this was not due to the track I was listening/recording. I talked to my songwriting/production teacher about it and he told me to change the buffer size both lower a higher to test it out but even though it sounded better at it’s highest setting it was still very distorted. He then told me to change the bit rate and the cache size but neither of these things worked. My question to y'all is (a) do you know maybe what's going on? and (b) do you have any idea how to fix it?
Thank you for your help!
