This document is intended to guide an end user through the process of fixing issues with no sound after a windows update. 

Information

Symptoms

Sound does not work after a Windows Operating System Update.

Cause

There is speculation that it is linked to a bad Intel driver that served in a parent capacity to the audio device.

Repair 

The fix is to switch to the MS built-in HD Audio driver instead of the Realtek driver on affected machines.  Attempts to reinstall the Realtek driver usually fail. 

Prerequisite: Applying this resolution requires administrative rights.  If you do not have them please contact the Help Desk and we will assist you. 

1. Go to Device Manager: Right-click the Audio driver with the yellow exclamation mark
2. Click on Update Driver
3. Browse My Computer for Driver Software (NOT search automatically)
4. Choose "Let me pick from a list of available drivers on my computer"
5. Select the option at the top of this list (this is the Microsoft provided HD Audio driver)
6. Click Next
7. Wait for the core driver to re-install
8. Complete
