Title says it all.
audio is not working @ 4K @ 100Hz/120Hz even on the latest 515.43.04 beta. Going down to 1440p@120Hz at least I have sound working.
Affected users please post here. The [ old thread] ([470.57.02] Nvidia 30-series HDMI audio stops working when switching from 60Hz to 120Hz)title is not helping. Hopefully this one will caught Nvidia attention.
