Minecraft plays without any sound on my system. When I launch the game, I see the following in the "Game Output" tab of the Launcher:
[12:53:05] [Sound Library Loader/INFO]: Starting up SoundSystem... [12:53:06] [Thread-6/INFO]: Initializing LWJGL OpenAL [12:53:06] [Thread-6/INFO]: (The LWJGL binding of OpenAL.

Here's the entire content of the "Game Output" log window, in case it's helpful:

I was able to work around this problem locally by building libopenal.dylib from source (using the current master from https://github.com/kcat/openal-soft) and then updating the contents of ~/Library/Application Support/minecraft/libraries/org/lwjgl/lwjgl/lwjgl-platform/2.9.2-nightly-20140822/lwjgl-platform-2.9.2-nightly-20140822-natives-osx.jar with the new library; after doing this, sound works normally (but note that this work around also requires defeating the update check that would overwrite a modified local copy lwjgl-platform-2.9.2-nightly-20140822-natives-osx.jar with a fresh copy from the server).
I'm happy to help debug the issue further, if needed.
