hi so im trying to add a custom sound to a block but i cant seem to get it to play the sound.

this is my sounds.json:

{
"watermill": {
"category": "ambient",
"credits": [
"freesound"
],
"sounds": [
"dsurround:ambient/watermill"
]
}
}

which is pointing to assets/dsurround/sounds/ambient/watermill.ogg

and part of my config.json

  {
  	"blocks": [
  		"immersiveengineering:woodenDevice1"
  	],
  	"chance": 90,
  	"sounds": [
  		{
  			"sound": "dsurround:watermill"
  		}
  	]
  },

not sure why it wont play, if i set the sound to waterfall.0 it will play that sound, but it wont play my custom sound that i have added to my resource pack :s

is there something i am doing wrong?

Mod Version:
1.10.2-3.4.9.17

I would like how to do the same but with items :c
