Thank you  @Infinitoar and  @druid.  I am just in the middle of midterms as of yesterday so I will definitely try out the suggestions and see if this will clear up the crackling and skipping.  I did have a chance later that night to play around with the audio so I will continue to refine the settings.
Thanks so much again for such a quick response from both of you!  I am pleasantly surprised how quickly I got help!
