It happened just today spontaneously.
I can't watch videos and can't listen to music. I tried using in-storage videos, youtube, netflix (it gave error 5.0).
I checked the internet connection, I can surf perfectly, even typing this question from the same phone isn't a problem. Just videos and audios.
Another problem is that i can't talk on calls too due to this problem. My phone hangs during call too.
I did the factory reset too but still no luck.
I'm using moto g4 plus (running on Android 7.0)
