Samsung(nvidia High Definition Audio)
Unable to get Dolby ATMOS to show as a supported audio format in the sound properties with Nvidia High Definition Audio Driver. I don't have an answer for you but I can say it works on the 2080ti using the latest drivers. The same audio device is used across the RTX range.

How To Use Nvidia High Definition Audio
I have an nvidia geforce gt 440 and I have lost my sound, insofar as the xp sounds and audio devices is concerned. On the other hand I can, for instance, play a movie, in either xbmc or vlc and I do have sound. I have no idea what happened and its a mystery.
I have downloaded nvidia audio drivers, from nvidia and also nvidia display drivers and have installed them both. It made no difference. The device manager has no fewer than 5 nvidia high definition audios listed and the last one has the dreaded yellow exclamation mark. The first 4 are using an nvidia driver v 1.3.24.2, the one with the exclamation mark has v 1.3.23.3. When I try and update this driver it tells me that it cannot find the software.
Thoughts?
