Clip won't play music or books

Occasionally, the clip would resume playing a book, but there was no sound.  Turning it off or going home and winding my way back to audiobooks or songs would correct the problem.  Today - nothing!  I go to the book or song, and the clip does nothing…does not start playing at all.

Has anyone seen this?  Hope you know a fix!

Did you try a system reset (on button in the uppermost position for 15-20 seconds)?
