Hello all, this is my first time posting here. To start of with explaining my problem in hopes of finding a solution, I will write down the model of my laptop and OS (if any more is needed, I am happy to comply): HP Pavillion dv6910 Windows 7 Ultimate 32 bit This laptop has been working fine until a few days ago. Since then I have been through a lot to try to fix it. I've tried downloading drivers found on the HP website, googling my problem to find various websites that talk about it, and system restore. These didn't help me so I have decided to take a more direct approach by posting here. I have formatted my computer and reinstalled Windows 7 in the hopes of fixing it and to my relief the sound was working great. But, after a while of using the computer, I wanted to watch a video, and no audio was heard. I have looked for the drivers and nothing is there. The sound just disappeared. I really need help, and again, if any more information is needed, just tell me so.
