How to Fix No Sounds issues with Conexant Audio/Smartaudio on Windows 10

If your computer has a Conexant audio device and you upgrade it to Windows 10, there is a slight possibility that the computer may no longer be able to play audio following the upgrade. This issue has been known to plague a good percentage of all the users with Conexant audio devices who upgrade their computers to Windows 10. The cause of this problem, in almost all cases, is that the Conexant audio drivers on the affected computer are incompatible with Windows 10, and Windows was unable to upgrade the drivers during the Windows 10 upgrade.

This issue can be fixed by simply updating the Conexant audio drivers on the affected computer, but since that didn’t automatically happen during the Windows 10 upgrade, you are going to have to do it manually. In order to do so, you are going to have to first download a driver package for your computer’s Conexant audio device that is not only newer than the one already installed but is also guaranteed to be compatible with Windows 10. Since Conexant does not release drivers for its audio devices on its own website, you are going to have to download the new driver package from the official Support website of the affected computer’s manufacturer (Acer or HP – for example).

Method 1: Update Driver Manually

Once you have downloaded and the new driver package for the affected computer’s Conexant audio device, you need to install it. In order to install the new driver package, yo

  1. Press Windows Logo key + R to open a Run
  2. Type devmgmt.msc into the Run dialog and press Enter to launch the Device Manager.
  3. In the Device Manager, double click on the Sound, video and game controllers section to expand it.
  4. Right-click on the Conexant audio device and click on Update Driver Software… in the context menu.
  5. Click on Browse my computer for driver software.
  6. Click on Browse….
  7. Navigate to the folder in which the new driver package is located and click on the folder to select it.
  8. Click on OK.
  9. Click on Next, and then wait for the wizard to locate the new driver package and install it.

Once the new driver package for the affected computer’s Conexant audio device has been installed, restart it and, if all went well, the sound will have been restored.

Method 2: Disable Audio Enhancements

In some cases, if you have enabled certain sound enhancements, the issue might be triggered. Therefore, in this step, we will be disabling all Audio enhancements. For that:

  1. Right-click on the “Speaker” icon in the bottom left side of the screen and select the “Open Sound Settings” option.
    Clicking on the “Open Sound Settings” option
  2. In the top right side, select the “Open Sound Control Panel” option and right-click on your “Speakers”.
    Selecting the “Open Sound Control” Panel option
  3. Select “Properties” from the list and click on “Enhancements” in the next tab.
  4. Check the “Disable All Enhancements” option and click on “Apply”.
    Checking the “Disable All Enhancements” option
  5. Select “OK” to close the window and check to see if the issue persists.

Note: You can also try to boot your computer in a clean boot and check if that helps with the issue.
