no sound at all on w10 home

gateway nv53 laptop with conexant hd sound has no sound at all
everything appears normal
no yellow marks in device mgr
uninstall/reinstall or update driver no effect
was working fine till windows updates
even microsoft tech couldnt figure it out
any help would be appreciated

See Windows 10 no sound SOLUTION (CONEXANT) - Windows 10 Forums

solution offered was tried didnt workent back to w7 viola sound is fine thanks microsoft

If the Conexant is not at least Win 8.1 compatible it may not work in Win 10. I would have deleted the Conexent driver (reboot) and see if Windows installs the generic, basic function, High Definition Audio driver. If it does and you get sound that would confirm that the Conexant hardware is compatible and you need a Win 10 compatible driver. If Windows does not install the High Definition Audio driver then that says the Conexant hardware is not compatible.

sound originally worked windows update killed the sound now nothing works

I just installed Win 10 (1511 version) on a Lenovo Z560 Ideapad (laptop). There are no Lenovo Conexant Win 8/8.1/10 drivers for this model. I used the Win 7 drivers and installed them using the Win 7 compatibility mode. The Conexant installed OK including System Mixer.
