I'm running Godot v3.4.3.stable.flathub [242c05d12] on Pop!OS, which is basically an Ubuntu variant

I'm trying to export to HTML.. I have Export Mode set to Export all resources

However, music isn't being played when run via website.

The music works (using SoundManager) while running locally via Godot editor

The music files (.mp3) are within the project structure.

Any other ideas where how to make music play when exporting to HTML?
