Audiobox USB has hissing noise on Mac OS Sierra 10.12.6

After I record, a hissing sound is very apparent on playback.

This has happened on 2 different computers (same OS) using the same Audiobox USB device. One was recorded using Adobe Audition and the other was just a native MP4 file for a screenshot video I was doing using Snagit. I've tried using different USB ports and have switched the mic jacks on the Audiobox USB. I have also done recordings without using the Audiobox and they are clear and without the hissing.

A clue is that on one of the computers if I removed the USB coection and then plugged it back in after a moment the hissing would stop. After a few minutes though it would retu. I have not been able to replicate this temporary solution on the 2nd computer.

Any help would be greatly appreciated
