Moto g videos out of synch

[AC Question]

I have a motorola moto g phone and everytime i watch a video from youtube, facebook or instagram, the video pauses after 3 sec and then plays but sound and image are tottaly unsynchronised. I havent change anything the last days and this happened out of the blue

Welcome to Android Central! Which generation of Moto G? Does this happen on both wi-fi and mobile data? Does it persist after a reboot?
