M31s Have Reverse Charging Feature So The  the unwanted  Power Is also Producing from The Type-c And Head Phone Jack so while We Using Earphones While the Sound Came And The Unwanted power Producing sound is also Effectively noice So Samsung Have A manufacturer problem  Thats Not A Software Bug Fix So Samsung Can't Solve This Issue To Your Mobile .They Have to give a Turn off Reverse Charging Feature in Next Update
