I can't set my sound default. I recently got my computer updated and a few hours later, my sound stopped working, then my videos, too. I reinstalled my computer, but when it got to the point where you set sound defult, it wouldn't work. The sections "Configure" and "Properties" worked, but "Set Default" wouldn't. I am so frustrated because I need sound and video to do a lot of things on my computer.
My product name is: Windows 8 HP Pavilion Sleekbook 15 PC

Can somebody please help me?
