If it's still not working you can try adding that mod first and then adding whatever other mods you're using one at a time to see what the problem is. Just make sure you delete your Yakuza 0 folder and then verify game files on steam or whatever the equivalent of that is on other platforms you are playing it on before doing that.

could it be that this doesn´t work with other mods? which is weird because I don´t have a any other sound mod installed
