NVIDIA HDMI Audio Driver

The NVIDIA HDMI Audio driver enables sound output through the HDMI connection on a compatible NVIDIA graphics card, sending audio to a monitor, TV, or AV receiver. You need it if you use your display’s speakers or an HDMI-connected sound system, especially when audio is missing after a Windows installation or graphics driver update.

Key Features

• HDMI audio output: Routes PC audio through a compatible NVIDIA graphics card, so one HDMI cable can carry both video and sound.
• Digital sound support: Supports stereo and, where supported by your hardware and audio setup, multichannel playback for movies, games, and other media.
• Windows audio integration: Makes compatible HDMI audio devices available in Windows sound settings, where you can select your preferred playback output.
• Support across Windows generations: Appropriate driver packages are available for supported NVIDIA hardware running Windows 11, 10, 8, or 7. Compatibility depends on the graphics card and driver release; one package does not necessarily support every system.

How to Install NVIDIA HDMI Audio Driver

1. Identify your hardware and Windows version. Find your NVIDIA graphics card under Display adapters in Device Manager, then confirm your Windows edition and system type. For Windows 10/11, check Settings > System > About.
2. Choose a compatible package. Before starting your NVIDIA HDMI Audio driver download for Windows, verify that the package supports both your GPU and operating system. The audio component is commonly included with NVIDIA graphics drivers. Choose a trusted free download rather than a paid driver-update utility.
3. Run the installer. Open the downloaded package and follow the prompts. If component selection is available, ensure HD Audio Driver is selected, then install the package.
4. Restart if prompted. Connect your HDMI display or receiver, switch it to the correct input, and confirm that its speakers are enabled and not muted.
5. Select and test the output. Open Windows sound settings and choose your HDMI display or receiver as the playback device. Play audio to check the connection. This driver does not control speakers connected to your motherboard’s analog audio jacks.

Keep the driver updated to benefit from applicable compatibility improvements and fixes. Use the latest version that explicitly supports your graphics card and Windows release, rather than assuming the newest package supports older hardware. If an update causes audio problems, check your output selection first, then consider rolling back to a previously working driver.

Common Issues and Fixes

• HDMI audio not detected: Check the TV/monitor is connected directly via HDMI/DisplayPort and that “NVIDIA High Definition Audio” is enabled in Device Manager. Rescan hardware; if absent, reinstall the NVIDIA graphics driver with the HD Audio component selected.
• Install fails: Close audio apps, run the installer as administrator, and use Custom > Clean Install. If it still fails, remove old NVIDIA HDMI audio entries in Device Manager and reboot before retrying.
• Version conflicts/no sound after update: Keep NVIDIA HDMI Audio matched to the installed graphics driver; don’t mix standalone audio drivers. Use DDU, reinstall the same NVIDIA package, then set the NVIDIA HDMI output as the default playback device.
