Client> [07:20:29] [Client thread/WARN]: Unable to play empty soundEvent: meta:missing_sound
I looked in the .minecraft/assets directory, and saw a new SOUNDS (all upper case) subdirectory.
I renamed "SOUNDS" (all upper case) to "sounds" (all lower case) and the sounds started working again.

I haven't had the problem since I renamed the directory.
There was another player on a 1.7 server that had the same issue, and this fix resolved it, but I don't know what exact version he was running.
I put my solution here to help people that searched for "no sound". I don't know if it's helped anyone else or not.
Is this still a concern in the latest Minecraft version 13w48b? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
