HP EliteBook 850 G3
Microsoft Windows 10 (64-bit)

I had audio issues, speakers would intermittently not work.  I upgraded the driver to sp76702 per the following advisory:

 

-------------------------------------------------------

Document ID: c05288869

Version: 1

Advisory: HP EliteBook and ZBook G3 - Audio Not Working After Reboot, Speaker Icon Has Red X
-------------------------------------------------------
 
After the upgrade, I can no longer get audio through my docking station or the speaker jack on the right side of the laptop.  Tested my external speakers with a different source (smartphone) and they work fine.  I submitted a case today with HP.
