[INFO] [STDOUT] Error in class 'SourceLWJGL OpenAL Making game unplayable?

[brian hatley]

I cant figure out how to get rid of this error? it just came up out of nowhere.

i read it may have been a chunkloading issue, which made sense because as soon as i left my main factory , my import bus stopped sucking out of the white ender chest i have set up there.
But i have green enderchest at my second factory and it continued to pull items out as normal.

So i took away all the chunk loaders from that area and still kept getting weird errors.

Then i read its from the ic2 sound files, i went into the config and disabled it and adjusted the sound thing to 10, instead of 32. Still getting this same error....

WHHAT DO I DO?! =(((

[Audhumbla]

I have the same error sometimes, and when I do it lags like crazy. Any solution yet?

 

[colonelkime]

disable sound/music and restart your client

lag disappear!

 

[Javik]

I've been trying to learn exactly what the problem is. It comes down to figuring out the acronyms:

LWJGL = The Lightweight Java Game Library (LWJGL) is a solution aimed directly at professional and amateur Java programmers alike to enable commercial quality games to be written in Java. LWJGL provides developers access to high performance crossplatform libraries such as OpenGL (Open Graphics Library), OpenCL (Open Computing Language) and OpenAL (Open Audio Library) allowing for state of the art 3D games and 3D sound.

OpenAL = OpenAL (Open Audio Library) is a cross-platform audio application programming interface (API). It is designed for efficient rendering of multichannel three dimensional positional audio.

,

So "Channel null in method 'stop'" means that OpenAL is being told to stop playing a sound channel, but the channel number it is trying to stop is invalid and set to "no value" (null ... which is not necessarily zero either).

It is possible that a huge number of sound channels are being created. Since they are not being properly destroyed when they are no longer needed, the sound channels stay active longer (or forever) causing lag for the client, due to the client trying to mix all the unneeded channels together.

I'm having this same issue, has anyone managed to fix it?

 

[Bickers]

its normaly from IC2 but as you disabled the sounds and still getting it my guess is its coming from the adv jetpack so disable sounds in gravisuite to see if that helps

 

[X_Ender_X]

How do i disable the IC2 sounds? I have already managed to disable the sounds from Advanced Machines, and Gravisuite, but still have the error.

 

[UniZero]

How do i disable the IC2 sounds? I have already managed to disable the sounds from Advanced Machines, and Gravisuite, but still have the error.

The config file for ic2.
