The Conexant 20585 SmartAudio HD driver allows Windows to communicate with the Conexant audio hardware in your computer, supporting sound playback and microphone input. Installing a compatible driver can help restore missing audio devices or resolve sound problems caused by an incorrect or damaged driver.

Key Features

• Speaker and headphone playback: Supports audio output through the computer’s built-in speakers and compatible headphone connections.
• Microphone input: Enables recording and voice communication through supported internal or external microphones.
• Windows audio integration: Makes the audio hardware available to Windows sound settings, where you can select playback and recording devices and adjust volume levels.
• Hardware-specific controls: Depending on your computer model and driver package, may provide SmartAudio settings for additional audio configuration.

How to Install

1. Confirm your hardware and Windows version. Open Device Manager and check the audio device under “Sound, video and game controllers.” If it appears as an unknown device, compare its hardware IDs with the driver package’s supported devices. Also verify whether your Windows installation is 32-bit or 64-bit.

1. Choose a compatible package. Select a Conexant 20585 SmartAudio HD driver intended for your computer model and operating system. For Windows 11, 10, 8, or 7, check the package’s stated compatibility rather than assuming that one download supports every version. Computer manufacturers may customize audio drivers for their hardware.

1. Prepare and run the installer. Close audio applications and extract the download if it is compressed. Run the included setup program with administrator privileges, then follow the installation prompts.

1. Use Device Manager if no installer is included. Right-click the audio device, select “Update driver,” and choose the option to browse your computer for drivers. Point Windows to the extracted folder and allow it to search for a matching driver.

1. Restart and test your audio. After installation, restart the computer and check speaker, headphone, and microphone operation in Windows sound settings. If there is no sound, confirm that the intended playback device is selected and that neither the application nor the system volume is muted.

If the new driver introduces problems, use “Roll Back Driver” in Device Manager when available, or reinstall the audio package recommended by your computer manufacturer.

Common Issues and Fixes

• Install fails or stalls: Close audio apps, run the Conexant installer as administrator, and first uninstall any existing Conexant SmartAudio entry in Apps & Features and Device Manager under Sound, video and game controllers. Reboot before retrying.
• Device not detected: Confirm onboard audio is enabled in BIOS/UEFI, then in Device Manager use Action > Scan for hardware changes and check hidden devices. The Conexant 20585 needs the Microsoft High Definition Audio bus present.
• Version conflicts/no sound after Windows Update: Windows may replace Conexant with a generic Microsoft driver. Use Device Manager > Roll Back Driver, or Update Driver > Browse > Let me pick > Conexant 20585 SmartAudio HD. Disable automatic driver updates if it recurs.
