The sound action plays a sound in the world. Here is an example, this will play the anvil sound near all players every 3 seconds 5 times repeated:
# This is placed inside an event just like any other action is
sound 1:
# * The name of the sound that will be played (refer to resources for list of all sounds)
type: 'block_anvil_land'
# The target for this action, this will play for all players in the world
target: 'all'
volume: 0.5
pitch: 0.5
# Amount of times the sound will be repeated
repeat: 5
# Delay in ticks between repeats (20 ticks = 1 second)
intervalTicks: 60
# The location relative to the targets position so this will play for each player 5 blocks away from them on the X and Z axis
location:
x: ~5
y: ~0
z: ~5
