is there a way you can make config system to enable and disable entire sound system you use so its 100% vanilla?

i like ur mod for extra biome tweaks. unless u can make seprate mod just for biome stuff

You can try the Preset for turning everything off.

it doesnt turn off the system stil get sound crashes all the time esp nether castles

also what Preset disables your sound system.

So you mean you literally want to turn off the sound system? Well, it's the Minecraft sound system so I am not sure what you need to turn off. If you want more detail as to what is going on you can check up on it here.

but doesnt ur mod add in custom sound effects and custom background musics?

Honestly I am confused now. I see two subjects in this issue:

1. You mention sound system in regards to crashes. That's Minecraft.
2. Sounds added by mod. Yes, my mod adds sound and particle effects as well as some huds. If you want to disable most if not all effects in the mod you can apply the Preset "Turn off ALL Dynamic Surroundings options".
