Re: how to repair error 52

Welcome to the Forum, Rocky,

If you are still having problems with this, here's a place to start...


You probably need to reload that audio driver.  There are several ways to do it.  You may already have the software on your system, you may need an updated driver...


You can go to the top of this page "Support and Drivers" - or  you can post your exact model and OS and we can help you track down your web page and your driver.  If you have Hp Support Assistant loaded (latest version), you can use "Get Assistance" to have it take you to your webpage and download the driver.


Download the driver and try the standard install first: 

Download, double click and install. 


If that doesn't wor, then Try This:

NOTE: Replace the name "IDT High Definition Audio CODEC" with your driver name!


Audio Driver “Uninstall”

Control Panel -> Device Manager -> Sound, video and game controllers

          Right-Click   IDT High Definition Audio CODEC -> Uninstall


  • Shut down the system
  • Reboot
  • The driver reinstalls at login



Manual Driver Installation:

Control Panel > icons > Device Manager > (Highlight)  IDT High Definition Audio CODEC >

                      Right-Click > Update Driver Software > Browse my computer for driver software

                      Browse to  C:\SWSetup\sp*

                      Be sure the “Include Subfolders” box is CHECKED



If all that doesn't bring joy..

here is a link for the same problem that (after the driver install) includes a change to your sound settings.  I personally dislike the Enhancement - Loudness Equalization - but for some situations, it's necessary; and it sometimes does work when other solutions do not.  I have a great deal of repect for DavidPK.  Please read through this Post:


Good Luck!


I hope this helps.
