As of right now, this mod isn't able to be updated for next gen. In fact, as far as I know, no audio mod will be able to be updated for next gen until we have sound tools for changed formats. You can read more from the author of the sound tools from the post on their page.
Looks like mod author not going to make pass to NG version. Perhaps no interest in game anymore. At least to make a sticky post, so, people will stop asking for 4.04 version.
You guys could try this mod instead, its for next-gen and not exactly the same but works pretty well. https://www.nexusmods.com/witcher3/mods/9197?tab=description
It also works with FMC Audio Remaster quite well, or at least I've not had any issues so far: https://www.nexusmods.com/witcher3/mods/11011?tab=description
