Question NVIDIA High Definition Audio - Where is it?

[Ship_Rek]

Windows 10 device manager shows that I have three different "Nvidia High Definition Audio Devices". I am using the Realtek Hi Def Audio with my speakers plugged into the jack on my Asus mobo.

I'm having the well-known Realtek audio/video desync issue and have tried all of the suggested fixes with nothing working. Last resort is to add a new, non-realtek sound card. I don't want to buy one if I don't have to and noticed these Nvidia audio devices listed in my system. But... my RTX 2080 gpu doesn't have any audio jacks on it. I'm guessing these devices are used to only pass sound through HDMI. Just asking to confirm and try to understand what they're here for.

They come as part of the NVIDIA GPU driver updates as required (usually for audio through HDMI for example as you stated). Same as the AMD systems install their own. The virtual audios can be used for NVIDIA streaming devices too.

Worst case you can disable them using Autoruns so that you aren't removing them entirely from your system if needed later.

Graphics cards equipped with a sound chip don't have 3.5mm audio jacks ---- audio is via the card's HDMI port.
