Video playback has popping/clicking sounds

A

AC Question

I just got the LG G4 a few days ago, mostly for the great camera. Today I attempted to video my son doing a monologue for an audition, and there is a clicking/popping sound on the playback. AFter a quick internet search, I did what a few people suggested: turn down the volume. No go! Made sure my hands weren't moving while holding it. Same problem. Basically it is so bad that I can't use my phone to video the monologue. It is a distracting, annoying clicking sound.

Please help!
