I have tried updating the LWJGL to 2.8.4 and to 2.9.0, neither had any effect. Also have tried reinstalling the launcher, and the mod packs. Anyone have any idea what I am doing wrong? This worked fine a couple days ago and no changes have been made since then that I know of.

The last thing in your log says its trying to start Sound.
check if your sound drivers are up to date?
