NVIDIA HD Audio Driver

NVIDIA HD Audio Driver by NVIDIA Corporation

NVIDIA HD Audio Driver is a Windows system driver that enables digital audio output over HDMI and DisplayPort from NVIDIA graphics cards to connected displays, TVs, soundbars, and AV receivers. It integrates with the Windows audio stack, appearing as “NVIDIA High Definition Audio,” and delivers reliable, synchronized audio for gaming, video playback, and everyday use.

Key features:

• Digital audio over HDMI and DisplayPort from NVIDIA GPUs
• Stereo and multichannel LPCM (up to 7.1 channels), with sample rates and bit depths dependent on your GPU and display
• Pass-through for compressed formats such as Dolby Digital and DTS; support for high–bit rate bitstreaming (for example, Dolby TrueHD, DTS-HD Master Audio) may be available with compatible hardware, display, and playback software
• Automatic EDID-based detection of supported formats, channel counts, and sample rates
• Per-display audio endpoints for multi-monitor setups
• Works with standard Windows audio APIs (e.g., WASAPI, DirectSound)

Typical uses:

• Connecting a PC to a TV, soundbar, or AV receiver via HDMI for gaming and home theater
• HTPC setups that require audio and video over a single cable
• Multi-monitor configurations where certain monitors include built-in speakers

Installation and compatibility:

• Installed as part of the NVIDIA graphics driver package for Windows; you can choose it during a Custom installation
• Compatible with supported NVIDIA GPUs and Windows versions corresponding to your driver release
• Listed in Device Manager under Sound, video and game controllers as “NVIDIA High Definition Audio”

Notes:

• You do not need this driver if you only use a motherboard’s analog outputs, a USB DAC, or another dedicated sound card
• When a new display is connected, Windows may set “NVIDIA High Definition Audio” as the default playback device; you can change the default in Windows Sound settings
• For advanced audio bitstreaming, ensure your GPU, display/AV receiver, HDMI cable, and playback software support the desired formats

For the most secure and up-to-date version, download the driver through NVIDIA’s official website or GeForce Experience.
