The ATI HDMI Audio driver enables sound output through the HDMI connection on compatible ATI graphics hardware. It lets Windows send audio to a connected monitor, TV, or AV receiver, so you can carry picture and sound over a single cable. For Windows 11, 10, 8, or 7, choose a driver package that matches your graphics model and operating system, as support varies by hardware generation.

Key Features

• HDMI sound output: Allows compatible ATI graphics hardware to deliver audio to an HDMI-connected display or receiver with audio playback capability.
• Windows audio integration: Makes the HDMI audio endpoint available in Windows sound settings, where you can select it as your playback device.
• Compatible playback formats: Supports audio formats and channel configurations available through your graphics hardware, driver, and connected audio equipment.
• Graphics and audio coordination: Works alongside the graphics driver to support audio playback while using an external HDMI display.

How to Install

1. Identify your hardware and Windows version. Open Device Manager to check your ATI graphics model, then confirm your Windows edition and whether it uses a 32-bit or 64-bit system. Do not assume that an older ATI device has a compatible Windows 11 driver.

1. Choose the matching driver package. Download a package that explicitly supports your graphics hardware and operating system. ATI HDMI Audio components may be included in the graphics driver package rather than offered as a separate installer.

1. Run the installer. Close open applications, launch the downloaded setup file, and approve the administrator prompt if requested. Follow the instructions and include the HDMI audio component if the installer offers a component selection.

1. Restart and connect your equipment. Restart Windows if prompted, then connect your monitor, TV, or receiver using HDMI. Make sure the connected equipment is powered on and set to the correct HDMI input.

1. Select and test HDMI playback. Open Windows sound settings and choose the connected display or HDMI audio endpoint as the output device. Play a test sound and check the volume on both Windows and the receiving equipment. If the output is missing, check Device Manager for driver warnings and verify that your display supports audio playback.

Common Issues and Fixes

• Install fails or rolls back: Run the installer as administrator, temporarily disable antivirus, and remove any existing ATI HDMI Audio entries in Device Manager (including hidden devices) before reinstalling.
• Device not detected: Confirm the GPU’s HDMI output is connected to an active display, install the correct ATI/AMD graphics driver first, then check Sound settings and enable “ATI HDMI Audio” under disabled playback devices.
• Version conflicts or no sound: Match the HDMI audio driver to your GPU and Windows version; uninstall duplicate Realtek/ATI HDMI audio drivers, reboot, and set the ATI HDMI output as the default playback device with a supported sample rate.
