In the sound_definition.json file which determines where sound is played, “sounds/music/game/tears” with a volume of 0.30 is listed among the other nine music tracks in the sound group “music.menu”. Not only is “Tears” not suppose to play over the main menu, the directory being wrong also results in a blank audio file for the sound_definition.json file.
Problem has not been addressed yet in the latest Bedrock preview:
