The Conexant Audio Driver For AMD HDMI Codec enables Windows to communicate with the supported HDMI audio hardware in your computer. It helps deliver sound through an HDMI connection to a compatible monitor, television, or AV receiver. Select a package intended for your exact PC model and Windows version, as compatibility can vary between hardware configurations.

Key Features

• HDMI audio output: Provides driver support for sending computer audio to an HDMI-connected display or audio system, where supported by the hardware.
• Windows sound integration: Allows compatible HDMI audio hardware to appear in Windows playback settings so you can select the appropriate output device.
• Playback troubleshooting: Reinstalling the correct driver may resolve problems caused by missing or damaged driver files, such as an unavailable HDMI audio endpoint.
• System-specific compatibility: Packages may be available for Windows 11, 10, 8, and 7. Check the individual download’s supported operating systems and architecture rather than assuming one installer covers every version.

How to Install

1. Confirm your hardware and Windows version. Check your PC model and open Device Manager to identify the audio hardware. Confirm whether your Windows installation is 32-bit or 64-bit before selecting a download.

1. Download the matching package. Choose the Conexant Audio Driver For AMD HDMI Codec package approved for your computer and operating system. If the device listing is unclear, compare its hardware IDs in Device Manager with the package’s compatibility information.

1. Run the installer. Extract the downloaded archive if necessary, then launch the setup program and follow the prompts. If the package contains only driver files, open Device Manager, right-click the relevant device, select Update driver, and browse to the extracted folder.

1. Restart your computer. Save any open work and reboot to allow Windows to finish loading the installed driver.

1. Select and test HDMI playback. Connect and power on your HDMI display or receiver, then choose it as the playback device in Windows sound settings. Play a short audio clip and check the volume on both devices.

If HDMI sound remains unavailable, verify the cable connection and display input. Some AMD systems rely on an HDMI audio component included with the graphics driver, so confirm your computer manufacturer’s recommended audio and graphics packages before trying another driver.

Common Issues and Fixes

• Install fails or rolls back: Run the installer as administrator, temporarily disable antivirus, and confirm the package matches Windows architecture. If setup still fails, use Device Manager > Sound, video and game controllers > Conexant/AMD HDMI Codec > Update driver > Browse to the extracted INF.
• HDMI audio device not detected: Check BIOS for onboard/HDMI audio enabled, install or update AMD chipset and graphics drivers, then rescan in Device Manager. Try a different HDMI port/cable and confirm the display supports audio.
• Version conflicts, static, or no sound: Remove older Conexant and Realtek audio entries with “Delete driver software,” reboot, then install the Conexant package. Set the AMD HDMI output as the default playback device and disable audio enhancements.
