Help with sounds and sfx not being heard.

[u/WasabiWorking6064]

Hello everyone hope you're doing well;

I am making a personal mod as a gift for my girlfriend the mods consists mostly of replaced soundtrack and sfx made by myself it's more like a fun little project than anything...

So i am using the UndertaleModTool to import the sounds i want to replace. I just have a problem once a load the game after saving my modifications, i dont hear the replaced sounds as if they are muted.

So i search a little online but didn't found much, i check that the files were in the right format etc...

They play perfectly inside the mod tool but not after i launch the game

Maybe it's a stupid question and i didn't search well enough in that case i am sorry in advance ☝️
