Fire extinguish sound doesn't work in survival, but it works in creative mode.
1. Light some netherrack (or anything else) on fire and then punch it to extinguish it. In survival you hear the punching a block sound for the block type behind the fire (netherrack in this example)
2. do /gamemode creative
3. Punch some more fire, the correct extinguish sound plays.
4. do /gamemode survival
5. Try again. Fire extinguish sound will not play.
Edit: When another player punches fire to extinguish it, the sound plays. It just doesn't work when the player himself does it.
And it appears that the extinguish sound might play twice while in creative mode
