Suddenly all recording devices stopped working for my G750JH. the mics are not responding, both built-in and external, and anything i try to record comes out as either a constant buzzing sound or just static.Please help!

My G750JH laptop has been doing since almost ever since I bought it. I would be playing a game, and then I do something that requires loading an asset, like for example opening my inventory, having a cutscene or a conversation start, opening a menu.....
