No problem. I also JUST discovered that snowballs, eggs, and arrows launched from a dispenser are also effected by the Friendly Creatures volume setting, which is just silly because there's no creatures involved in that at all. Droppers don't have this problem, but droppers also play different sounds, so it's definitely related to this sound category bug.
[Edit] Can add casting a fishing rod to the list of effected player sounds. Though I think it's the same sound file as throwing projectiles.
Title:
No player sound when friendly creatures turned off
Description:
Many player sounds are effected by the Friendly Creatures volume setting, such as hitting blocks (with a tool or your fist), footsteps, throwing eggs, and shooting bows. This makes sense from a logical standpoint; players are, technically, friendly animals. However, it doesn't make sense from a practical standpoint. When I'm working on or near my farm and my 200 sheep are driving me insane, I want to turn THEM off, not myself.
And even if it's intentional design — which I hope it isn't — it's still inconsistent. Player sounds like breaking blocks (different from only hitting them), eating food, and taking fall damage are unaffected by the Friendly Creatures volume setting.
Throwing projectiles such as eggs and shooting a bow are both effected by the Friendly Creatures sound option, as well. Strangely, eating food isn't effected.
I also recommend clarifying the title and/or description. Reading the title and description alone, without reading the comments, it's not difficult to miss that player sounds are effected.
You also can't hear the 'hitting' sound when you're breaking blocks with Friendly Creatures turned off. I think it's the same block-dependent sound that footsteps play.
Oh, hey, so that's why I crashed! I was just trying to make a new pick, and my game crashed. Happened in a crafting table. Only, for me, the pick and the items used to craft it were completely gone when I logged back in to the world. Like the opposite of a dupe bug.
