Exact same issue here. Start the game and can see menu is lagging. No different in game, it'll be lagging like crazy with no audio. I've found sometimes it will randomly load in without lag and let me play, but if I quit the game and go back on it'll be back to lagging/audioless. If I launch minecraft with another game open, it plays with sound and no lag so not sure what the deal is. PC is powerful enough to run the game so no issue with that.
