Minecraft 1.6.4 no sound

All minecraft 1.6.4 sounds are not working. I've tried completely reinstalling, pressing f3+s, pressing f3+t and nothing is working.

I noticed this in the log
[19:14:28] [Client thread/WARN]: Unable to play unknown soundEvent: minecraft:mob.sheep.say
[19:14:28] [Client thread/WARN]: Unable to play unknown soundEvent: minecraft:mob.sheep.say

I don't think the sound files are downloading at all.
