Ok so I thought that everything was fine without optifine, but since the sound had been on and off, I wasn't sure. Well this time it launched without optifine and it still has no sound. In fact, I removed every mod except forge 1.6.2 804. Vanilla minecraft works fine. (I've tested MANY times) I have been installing forge using the installer (I've tried many different forge versions. Every version I've tried on the new launcher has sometimes broken my sound.) Should I try launching installing forge using the old method instead of the installer? Here's the launcher console. I have not modified my jar at all apart from installing forge using the installer.
