I have experienced similar problems using an ION brand turntable with USB output to computer.
They have a community forum for users and ION techs to provide advice. (I could not find any Pyle Forums.)
Seems like the cheaper brands of turntables (ION and maybe Pyle) have poor tracking ability with LPs that were manufactured after the 1970’s (narrower grooves).
->Another idea for you is to use your Pyle to export to wav files and then convert to mp3 files using iTunes???
