Missing custom audio and some default audio on low tier iOS

Repro Steps:
1. Create ‘Pirate Life’ world from the template.
2. Approach the Pirate King and wait for dialogue to start.

Observed Results:
1) Only chat dialogue is displayed without custom audio (Pirate King voice or background music).

2) Except background music and Pirate King voiceover, we have noticed that following elements of the game are muted: chests, parrots, using tools (pickaxe, shovel, hoe, axe).

 

Expected Results: Audio is played correctly on low tier iOS.
