The HD Audio driver is part of the GPU’s driver package, which you can download the driver from Nvidia’s website. You first need to install the HD Audio driver. Setting up digital audio in Windows is pretty easy. Setting up Nvidia Digital Audio in Windows Nvidia HD Audio supports multiple audio channels and advanced audio formats used with Blu-ray movies and is compatible with Windows from XP to 10 and various Linux versions. Nvidia digital audio is superior to analog audio and S/PDIF, surpassing S/PDIF’s support for compressed multi-channel 5.1. 32 kHz, 88.2 kHz, 176.4 kHz formats, and sample size of 20 bit are, however, not supported since these are rarely used. The codecs support audio formats in 32 kHz – 192 kHz, sample sizes of 16 bit – 24 bit, and speaker configurations from stereo to 7.1. Nvidia has embedded sound controllers and audio codecs, starting with their GT212 GPU. Having said that, it’s important to note that Nvidia HD Audio does not support analog audio thus, you still need your computer’s sound card for your speakers, headphones, and similar analog devices. The Nvidia High-Definition Audio’s internal codecs provide audio output through an HDMI connection.

By integrating an internal audio card onto the GPUs that works as the sound controller to deliver stunningly clear audio, you would no longer need audio cables when connecting your computer to an HDTV or display monitor.

Nvidia fused audio and video into their graphics cards so you can have the best of both worlds in a GPU. If we have to connect our system to another display like HDTV or an audio-capable display for video output, too many cables can mess up our space and make it look disorganized. Often, we use analog audio for audio output from our PC.
