Error possibly cause of lag

http://pastebin.com/jqC9Nte1 this is a pastebin copy from the launcher the error spam is constant and it's this line

1. 2013-11-25 13:14:45 [INFO] [STDOUT] Error in class 'SourceLWJGL OpenAL'
2. 2013-11-25 13:14:45 [INFO] [STDOUT] Channel null in method 'stop'

I know it has something to do with sound but other than disabling sound is there a way to repair this. Google turned up minimal I found one download but wasn't sure if that was a real fix and was hesitant to try. Sorry if this has been answered. My mod pack is Direwolf20 1.5.2. Also noticed it doesn't occur near the machinery just if i get a certain distance away. Not completely sure that helps narrow down the problem.

http://sourceforge.net/projects/java-game-lib/files/latest/download?source=files this is the file that google turned up as a fix if somebody more computer savvy wishes to help.

Just bumping to hopefully find a response

I'm not sure if updating those files will fix it, but if you want to try it you need to use this guide, but substitute the .minecraft folder for the mod pack folder. Each pack has its own version of lwjgl and if this works you will need to update each pack you wish to use and every time you update. OpenAL, is Open Audio Library, try updating your audio and video drivers.

I tried it regretfully it repaired nothing both checking drivers and the update to lwjgl though the information was interesting and good to know =D the problem persists the same.

After doing a little more searching it appears to be an IC2 and OpenAL problem. The fix is to turn off IC2 sounds. If you are okay with editing config files you want to change the bolded part below of the IC2.cfg file. Note that the ellipses (...) mean that there is stuff inbetween that is not included in the quote. I just added it to help you find it. Hope this fixes it for you.

I went ahead and edited that. The sounds from the machines are gone but I am still getting the error. Thank you though for showing me that not only this mod but most have the ability to edit configurations. I'm only familiar with one mod and haven't played it for a long time. Friends got me hooked on FTB!
