The Conexant 20672 SmartAudio HD driver enables Windows to communicate with the Conexant audio hardware built into your computer. Installing a compatible package helps restore speaker and headphone playback, microphone input, and the audio controls available on your system. For Windows 11, 10, 8, or 7, choose a driver that matches both your computer model and Windows version, since compatibility can vary between manufacturer-specific packages.

Key Features

• Speaker and headphone playback: Provides the software interface Windows needs to send sound to supported built-in speakers and connected headphones.
• Microphone support: Enables recording and voice input through compatible internal microphones or external microphone connections.
• Audio jack functionality: Supports headphone and microphone jack behavior where implemented by the computer manufacturer.
• System-specific sound controls: May include SmartAudio settings for adjusting playback and recording options, depending on the driver package and hardware configuration.

How to Install

1. Confirm your hardware and Windows version. Open Device Manager and look under “Sound, video and game controllers” for Conexant 20672 SmartAudio HD. Check whether your Windows installation is 32-bit or 64-bit before selecting a download. If the audio device is unidentified, compare its hardware IDs with the package’s supported devices.

1. Choose a compatible driver package. Prefer a package intended for your exact computer model. Do not assume that a Windows 7 or Windows 8 driver will work correctly on Windows 10 or Windows 11 unless compatibility is confirmed.

1. Prepare for installation. Save your work and close applications that use audio. Creating a system restore point beforehand gives you a recovery option if the new driver causes problems.

1. Install the driver. Extract the download if necessary, then run its setup program and follow the prompts. If the package has no installer, open Device Manager, right-click the audio device, select “Update driver,” and browse to the extracted driver folder.

1. Restart and test the sound. After restarting, check the selected playback and recording devices in Windows sound settings. Test speakers, headphones, and the microphone. If sound stops working after the update, use “Roll Back Driver” in Device Manager when available, or reinstall the previous manufacturer-approved package.

Common Issues and Fixes

• Install fails or rolls back: Run the Conexant setup as administrator, close audio apps/control panels, and temporarily disable antivirus. Confirm the package matches Windows version/architecture; if Setup still fails, uninstall any existing Conexant SmartAudio entry in Programs and Features, reboot, then retry.
• Device not detected: Enable onboard audio in BIOS/UEFI. In Device Manager, show hidden devices and scan for hardware changes; look under Sound, video and game controllers for Conexant 20672 or an unknown device. Install the driver manually via Update driver > Browse.
• Version conflicts/generic driver: Windows may replace Conexant with High Definition Audio. Use Device Manager > Roll Back Driver or uninstall the generic device, reboot, install the Conexant package, then set Windows Update to not auto-install drivers until confirmed working.
