I was playing on a server and I have a villager farm. So obviously I shut my "Friendly Creatures" sound off. Then another player came online and was complaining that he did not have any minecraft sound. Then it occurred to me. I did not have a sound. The sound that plays leading up to the break sound. Otherwise known as "dig" sounds. These were not playing. So I turned up the "Friendly Creatures" sound again, dug a block and it had sounds. So I hope this sound bug gets fixed soon.
