In April i purchased an HP ENVY 17-J027CL 17.3" (750 GB, INTEL CORE i5 @ 2.8GHZ-3230M, 6 GB) from Ebay. It looks really great and everything was working just fine and dandy until...\nI don't know when it happened, the echoing sound. I noticed it maybe last week when I was Skyping my fiancee. All of a sudden, I started hearing the tv in my laptop! At first, I thought I was hearing things because that just doesn't happen. I started to hear myself talking and when I closed the laptop it sounded like it was crying for help.\nI try to fix things myself before I ask for help. I am at my wits end! Every solution I tried from Google didn't work! I surrender I need help!
