Minecraft Crashes On Startup When Using Forge

Posted May 18, 20169 yr

Hi, sorry if I'm doing something wrong, I'm new to these forums, and to forge in general. I just installed forge, and when I start it up it crashes and I get the following message:

Same error with me.

Just installed minecraft v1.9.4 and Forge 1.9.4.

Looks like some problem with the latest Java 8u91.

1.9.4 builds were temporarily broken, re-download should be fine now. Make sure you've cleared you cache before redownloading.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

Forge 1.20.1 OpenAL 40963 and 40961 in DynamicSoundFilters

I copied the mod from Fabric to Forge, but errors 40963 and 40961 appear, I still don’t know the reason, I tried it in a single world, it doesn’t reproduce, the reason for the error is unknown, sometimes it exists and sometimes it doesn’t. andre111/dynamicsoundfilters: GitHub repository
The ported code to Forge is no different from the original, so you can use the source code for testing. The same error occurred on the Fabric build, mods that were on both builds:
Sodium
Create
I only know that the error occurs along the following path: MixinSoundSystem call onPlay -> FilterManager call updateSoundInstance

My friend keeps getting disconnected from our Forge Server

It is, but that is mainly to set up configs per player, I think. I don't believe it is messing chest inventories. I can try to remove that one tho and see if it fixes anything.
