UR22 glitch/pop sound while recording

Hello. I just bought the UR22, as well as 2 condenser microphones. I am home from college, and left my new laptop at school thinking I wouldn’t need it. However I have been antsy to use my new gear. So I installed my UR22 onto my older laptop (running Windows XP) and I am using it with Audacity.

It has been recording fine, and sounds decent. However during playback, there will be random popping sounds, and the recording will almost glitch. The playback then jumps ahead about a second. Therefore, it is not recording straight through.

Is there any way I can fix this so it will simply record straight through and not glitch/pop?

Thank you.
