let me share this solution for all
Install the new version of your driver and of course uninstall the current version. After uninstalling the driver and reboot it to automatically reinstall it, the audio still may not work. Amazingly though, sometimes after putting the system in hibernate mode and coming back, the audio worked.
Hope it helps, if it doesn't , noaudiooutput.com have other suggestion. I used their solution and it works now.
