Hello,

I've spent a few days on this and trawled forums both here and the official Minecraft ones to no avail. With the move from being Forge/ModLoader compatible to being a total conversion BTW is no longer compatible with most other Minecraft mods. Which doesn't bother me except for the ability to replace sounds. Most specifically I miss Audiotori and maybe MAtmos. With Audiotori it was possible to replace vanilla sounds and music to freshen up MC.
Now of course it doesn't work and I've been trying to find an alternative. I've tried replacing the files in the Minecraft folder, just to have them overwritten by the launcher. I've tried replacing the files and tagging them read only, just to have Minecraft ignore them. I believe it does either a filesize check or hash check on the audio files and if they don't match it's no go.Now I've played around this a lot but I've had little luck. Has anybody found a way to make this work?

Any help will be apprecited.

I didn't find the right solution from the Internet.
