So Minecraft just started acting up on my comp. The sound suddenly stopped working. Weird thing is, if I am offline while I log in and opt to play in offline mode, the sound works fine. I can even reconnect to the internet and play on a multiplayer server after the game starts up, but then I'm not my character. Something else bizarre is going on. I tried deleting my .bin folder to force Mincraft to update but then it kept getting hung up while downloading. So I tried deleting the whole Minecraft folder to do a fresh install and it hung up again while downloading. So I pulled the Minecraft folder and the .bin folder out of the recycling bin and put them back to their original spot so I could at least play the game, and suddenly the sound worked! Well now this morning, the sound isn't working while playing online again. Any help will be much appreciated.
