No Sound After Windows 10 Update on HP Compaq C500 [Solution]

 Windows 10 home edition, HP Compaq C500 (c581wm)

Conexant High Definition SmartAudio HD2 Driver (for sound,video and game controller) does NOT work with windows 10 !

High Definition Audio Device Driver DOES WORK!

This is how mine was fixed

If reinstalling the driver doesn't work, then try using the generic audio driver that comes with Windows. 

Here's how: 

in Device Manager, right-click (or tap and hold) your audio driver 

> Update driver software... 

> Browse my computer for driver software 

> Let me pick from a list of device drivers on my computer, select High Definition Audio Device, select Next, and then follow the rest of the instructions to install it.
