I have tried using the headphones and speakers in the back and the front jack. I have even installed the Realtek drivers twice still cant hear anything from both the jacks i.e. the front and the back one. Before the problem occured when I tried to insert the cord the the back jack there was a sudden Loud noise and from that time the speakers and headphones have stopped working. Tried to troubleshoot but nothing happened.
PS- I have checked the Speakers and headphones on other devices and they work absolutely fine.
