I bought an Acer predator triton 300 3 days ago. Yesterday while playing a game I noticed that when i inserted my headphone in the laptop then sound was not coming in it instead, sound was coming from speaker itself. When i pushed headphone jack bit harder 2 - 3 times then a notification came that CAMERA IS TURNED ON and then headphone started working. Same thing happened with other earphones and headphones too. So, please tell me where is the problem? In audio drivers or in my laptop hardware? Where driver is not working or laptop headphone jack is not working? And how to fix it?
