Lost sound after upgrading drivers. How to fix?

On my laptop Asus F3JC when you connect headphones, the sound kept going on and on the speaker and headphones in the Sound menu (Windows 7) earphone is not displayed. Updated drivers for the speakers, the sound is all gone (and with headphones and in the speakers). Explain what I did wrong and now it is possible to fix it.

Keep away the old version of drivers (e.g., via system restore)
Drivers can roll back without system restore - Edna commented on April 7th 20 at 15:21

Look at off site driver for your laptop and do a clean install
