Pavilion dv6-6c35dx - Sound not working after a HP Support update

Question

Pavilion dv6-6c35dx with windows 7
I recently did a factory reset, and with the reset had to do all the updates. One of those updates from the HP Support assist was IDT High Definition Audio CODEC version 6.10.6381.0 on driver stwrt64.sys. And with that update i no longer have sound. When i put the cursor over the sound icon on the toolbar it says no headphones or speakers are plugged in. I already tried disabling and re-enableing the AMD HDMI output audio device through the control panel menus, didnt work, also it says its not plugged in. When i go into the hp supprt assist, to troubleshoot, to audio and sound, the status on the IDT says Error(52).
How do i fix this?

Hello everyone,
Thanks for posting on the HP Forums!
It would appear that you two are experiencing different issues. I will definitely address both of you!
First, I feel it would be wise to perform a System Restore. You can return the computer to a point before the issue existed. Here's how to do it: Using Microsoft System Restore (Windows 7)
If that doesn't work, then look at the below suggestions:
*Before any real troubleshooting, please put your computer in a clean boot state. This should prevent third-party programs from interfering. This document provides information on how to do it: How to perform a clean boot in Windows*
*Next, unlock a new Administrator account, so we can troubleshoot on a clean account. Open Command Prompt as Administrator, and hit Enter after typing the following: net user administrator /active:yes
You will be able to log out of your current user account, and log into the Administrator one.
*Finally, make sure all of your Windows updates are complete:
1. Open "Windows Update" in Control Panel.
2. Click "Settings", and then click "Install optional updates".
3. Next, click "Check for updates".
If that step doesn't work, then look below for the appropriate troubleshooting:
@epicness50 , you need to perform all of the steps in this document: No Sound from the Speakers (Windows 7)
Also, since there is a Device Manager Error 52 issue, you may want to look here for additional information and suggestions: Code 52: Windows cannot verify the digital signature for the drivers required for this device
*The above Microsoft document is for Windows Vista and Server 2008, but the troubleshooting can be done in Windows 7.
@LENNY12 , you mentioned you uninstalled and reinstalled Support Assistant. However, I'm going to ask you to do it again, but with a little more troubleshooting to address what could be causing the issue.
Source of the troubleshooting is my own post: HP Support Assistant Windows 8.1
Uninstall your version of Support Assistant in Control Panel, Programs and Features, then restart the computer.
Solution: Download Support Assistant from its own special home
1. Click on the following link: HP Support Assistant. It will bring you to the following page:
2. Click on "Notebooks, laptops, netbooks " under "Download HP Support Assistant". It will prompt you to download it. So save it, then run it AS ADMINISTRATOR.
If either of you are still experiencing issues,  I would perform a System Recovery to reinstall Windows. This will rule out which of the above options are to blame.
First, you should backup your data. I will provide information on how to do that: Backing Up Your Files (Windows 7)
Once this is done, it is safe to do the System Recovery. Here is some information on how to do this: Performing an HP System Recovery (Windows 7)
Thanks and have a great day!
