Hello
I am also trying to get VoiceFX to run in DaVinci Resolve 17.4.1 build 4. I have an up-to-date Windows 10 install, 471 Nvidia non-studio drivers, RTX 3080 Ti, 3900X CPU, 32GB of RAM, Nvidia latest SDKs for audio, video, and AR.
I have reached out to Xaymar (creator of the plugin) and he mentioned neither he nor Nvidia has any idea why it stopped working. Could you possibly take a look at the issue on the Resolve side? I am trying to edit a science popularization conference recording and clean up the camera audio. Without a cleanup the audio is too difficult to understand
