"minecraft:ambient_sound_interval" only works for the host

Verification builds:

Minecraft - Release_1130546 (1.7.0.3_beta-22)

Summary:
A component in the behaviour pack doesn't work for anyone but the host over Xbox Live:

"minecraft:ambient_sound_interval": {
   "range": 0.0, 
   "value": 1.25 
},

This component states that the ambient sound attached to this specific entity should loop every 1.25 seconds (Because it has a 0 delay between playing the ambient sound again).

However, this only works for the player hosting the world, everyone else hears the sound as if this component doesn't exist (No 1.25-second loop, just the natural delay between ambient sound).

Impact:
Players playing together will unexplainably experience gameplay features differently from each other because they're playing in multiplayer.

Repro Steps:

1. Download the 'Millionaire Mansions' map from the Store
2. Create a new world.
3. Have another player join your game from the friend list
4. Spawn an 'ATV' from the creative menu
5. Both observe the sound

Observed Results: 
Only the host will hear the looping sound. The other player will hear it from time to time.

Expected Results: 
Both players can hear the sound looping.

Screenshots/Videos attached: 
No

Notes:
You can find the component used in the behaviour pack through the vehicle_atv.json json found in the entities folder.
