Before some days I got the HP Pavilion dv7-4070us laptop and I like this laptop. After I get the laptop I have upgraded my laptop from windows vista to windows 7. After that I installed all the drivers in my laptop, all the things were working fine after that I updated my sound driver as I found these drivers on its official site. But after that I started facing one issue with my laptop. I am getting very low sound from my laptop speaker. In 100% volume also I am getting very low sound without beats. Please tell me how to fix this solution.
