UR22 Low Buzz and Slight Echo


I have been using the UR22 for several years now. However, I recently bought a new computer and reinstalled all my software and installed the most resent UR22 driver (1.9.9). I have set all of my settings to the same settings as my previous computer but I am experiencing a low frequency buzz and a slight echo in my voice recordings. I am using an Audio-Technica AT2020 condenser microphone and a Dell Inspiron 15 7000. All of my knobs are set to the middle as per my last set up and my +48 is switched on. Any advice? Is there an issue with the new driver?
