Sound from .bundle Firefox Error

I’ve trying to get sound from .budle file. And it works great except of Firefox (80, 64 bit). I’ve got following error:
The buffer passed to decodeAudioData contains an unknown content type. localhost:2000

[lime.utils.AssetLibrary] WARNING: Could not load “sounds/BtnClick.mp3”: Decoding audio data failed.

Tested on:
Firefox developer (80.0b7, 64 birt) works

Any idea what’s problem with regular Firefox browser?
