So I have an HP Pavilion dv6700 laptop and in December my sound stopped working and a red "x" appeared over my speaker. I tried restoring my computer many times and I have also tried to go to control panel then device manager but when I open up the device manager there is no option for sound and games which is what a lot of sites have been telling me to do. This is a really annoying problem and I would really appreciate any help. Thanks
