I'm using the FTB Ultimate Pack (I removed voxelmap and added Rei's Minimap | I also added in OptiFine) and when I'm in-game the sound doesn't work properly. Like the foot steps on the grass can't be heard, breaking block noises can't be heard, and things like that. I made sure my system audio was turned up and that the games audio was turned up. After about a minute or two it finally starts up. I have no idea what could be causing this lag, but I just wan't to get rid of it, because it is annoying.
