Just had the same problem after a (normal) restart on a Macbook Retina 10,1. Sound wasn't working anymore and most applications using sound hung up/waited for a ling time and then crashed (most annoyingly flashplayer, which caused firfox to hang). After deleting the folder pulse, sound instantily worked again.
