sound system bug

Ever since the new launcher came out I haven't been able to hear any sound from the game. If I ever want to play with sounds I have to use the old launcher which only allows me to play in 1.5 or lower and I that means I have to switch the folders every time. I've redownloaded the game multiple times but it still won't work. Here's a pastebin of the console. http://pastebin.com/eAdKvcjx
