If you are having problems with the Realtek High Definition Audio driver on Windows 7, the sound will fail to play. Here you will learn how to fix Realtek High Definition Audio driver issue on Windows 7.



When you meet Realtek HD Audio driver issue, you may see one of below common error messages in Windows.


“This device cannot start. Code 10″

“The drivers for this device are not installed. (Code 28)”

“Audio Driver Error: The following driver(s) either do not support the current audio format, or are in use by another application.”

“Bad DirectSound driver. Error code 88780078.”


To fix the issue, just update the driver. There are four ways you can use to update the driver.


1.Use Windows Update


You can use Windows Update to check for the updates. It may help install the audio driver. Open Windows Update by clicking Start -> Control Panel (View by Small icons) -> Windows Update. If you have turned on automatic updates, skip this way.


2. Install the Driver from Device Manufacturer


Some devices might come with a disc which contains the driver. If you have one for your sound card, you can use it to update the driver.


3. Download and Install the Driver from Realtek


You can find and download the driver on Realtek website.

After you go to the website,  click on High Definition Audio Codes (Software), and follow the on-screen instructions to download the right driver. To download the right driver, you need to know your system version (Windows 7 32-bit or Windows 7 64-bit).


Usually, the realtek driver can be self-installing. After you download the driver, just double click on the file to install the driver. If you cannot install it in this way, you can try to install it manually, then follow steps below.


1). Press Win+R (Windows key and R key) at the same time. A Run dialog box will pop up.

2). Type devmgmt.msc in the run box and click OK button.




3). In Device Manager, expand category Sound, video and game controllers.

Under this category, right-click on Realtek High Definition Audio. Then click Update Driver Software…




4). Click Browse my Computer for driver software.



5). Click Let me pick from a list of device drivers on my computer.


6). Click Have Disk…

7). Click Browse button and navigate to the location of the downloaded driver. Windows will find the .inf file. Then follow the instructions to install the driver.

    Dear all,
    I had a W7 (x64b) update. til then, every diagnostics is OK but I have no sound from my phones, headphone output & microphone. I updated each driver without success. If anyone can tell me which update (KB…) breaks my system and how to fix this issue…because MS staff didn’t want to do in order to push customers to get W10.

  • John F.

    This company keeps releasing new updates for sound every other week or so. Why do sound cards need so much updating? I have given up and just ignore them now. My sound has no issue on my computer.

    • camilla mo

      Dear John,

      The manufacturer releases drivers to fix bugs or add new features. Updating some drivers can boot your PC performance a lot.
