My client just downloaded the 1.7.9 release today, I'm on a server, and the game suddenly freezes. I have to force-quit the game, and this is the message in the development console:

[07:22:37 INFO]: Client> [07:22:37] [Client thread/WARN]: Unable to play unknown soundEvent: minecraft:liquid.splash

Scrolling up a bit, I see that the console displayed this message:

[07:20:55 INFO]: Client> Error in class 'LibraryLWJGLOpenAL'
[07:20:55 INFO]: Client> Source '64afd7fb-105d-4294-a41c-96448e36e3f5' not found in method 'play'

This also happens on every release of 1.7 that I get. I checked all of my audio drivers, they all say they're up-to-date, my video drivers are up-to-date. I can't figure out what's going on or how to fix it.
