How to Fix IDT High Definition Audio CODEC Driver Problem

By Camilla Mo in Driver Error
IDT High Definition Audio CODEC driver can fail to install through Windows Update or Device Manager, especially due to Windows 10 upgrade.  The common error could be as follows:

“Windows found driver software for your device but encountered an error while attempting to install it. 

IDT High definition Audio CODEC 
A device attached to the system is not functioning.”

If you meet this problem while installing IDT High Definition Audio CODEC driver, just use the two solutions below, then the driver will be installed correctly.

Solution 1: Reinstall the Driver

Follow these steps:

1. In Device Manager, expand category “Sound, video and game controllers”.

2. Right-click on IDT High Definition Audio CODEC and click Update Driver Software… on the context menu.

3. Click on Browse my computer for driver software.

4. Click on Let me pickup a list of device drivers on my computer.

5. Select High Definition Audio Device (Not IDT High Definition Audio CODEC) and click Next button. An warning message might pop up, just click Yes button. Then the driver will be installed successfully. 

This solution should fix the problem. If not, proceed to Solution 2.

Solution 2: Updating Drivers Using Driver Easy

The steps above may resolve the IDT High Definition Audio CODEC driver problem, but if they don’t, or you’re not confident playing around with drivers manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

1) Download and install Driver Easy.

2) Run Driver Easy and click Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to the IDT high definition audio driver to automatically download and install the correct version of this driver (you can do this with the FREE version). Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

    • Camilla Mo

      Hi Jade Yeates ,

      Happy Birthday to you! 🙂 I am glad that we could help.

      I’m not sure if you update drivers often. But it’s necessary to keep your drivers updated in order to have better PC performance.

      I’ll send you a license key of Driver Easy via email as a birthday gift. You can use Driver Easy to update drivers easily. I hope you’ll like it.

      You’re welcome to leave any comments again.

It worked right away after I did what you recommended. Thanks again. I don’t know why windows 10 make things so complicated and hard. I was much better with my earlier versions of windows.

      Hi Pratik,

      Thank you for your feedback.

      You can download the drivers for free. And if you want to have drivers installed automatically, upgrade to the PRO version.
      For more purchase information, please see

      Please leave your comments again if you have any further questions.

      • SilverGeek

        Great job Camilla Mo, thank you. Windows 10 Creators Update downloaded 17th April 2017 messed up my system and stole the codec.
        After a couple of failed attempts I went back to the “good old days” and restarted my system after reloading the codec.
        My 5.1 Surround Sound system is now working again.
        HP and Microsoft could not solve the problem but you did.
        You should be working for them at a VERY LARGE salary !
        They should both get their act together and give real support for their customers.
        I might now investigate “Driver Easy” if you have anything to do with it.
        Thanks again and have a good day.

        • Camilla Mo

  • shah

    Excellent tip, it worked perfectly for me…..Thank you so much

  • LJ

    It fixed the problem with solution 1. The icon of the sound no longer has the red cross. However, the sound does not work with the system speakers in the laptop. I tried solution no. 2 and I got the same results( no sound with speakers and sound with headphones)…something interesting is that the sound when using the headphones, works however, it is very low and when I turn the volume up, it echoes just when a microphone sound is turned up over the limit….
