Read on to find out what both drivers are good at and know if choosing between them is possible. The Realtek HD Audio driver, on the other hand, is used in all other forms of audio output, like speakers, headphones and more. Nvidia HD Audio is an audio driver used when you connect your PC over HDMI to a TV. With all the information that I gathered, I intend to make this guide so that you’ll know what Nvidia and Realtek High Definition Audio are and why they are separate. To do this, I made a few posts on Nvidia forums and read up on a few technical articles that went in-depth about Realtek and Nvidia audio drivers. I wanted to find out more about what these two drivers did and why Windows feels that its required for it to hand over audio control to Nvidia’s driver when I plug my PC into the TV. I already have an audio driver that came pre-installed from Realtek and wondered why the TV was using the Nvidia driver instead of the Realtek one.

I had noticed that whenever I plug the TV into the laptop’s HDMI port, the audio gets transferred over to Nvidia’s High Definition Audio driver. I have a small gaming laptop that I use with my TV to watch stuff and play games occasionally on the TV in my bedroom.Īn Nvidia GPU powers the laptop, and even if it isn’t the latest variant, it does the job well.
