Oh! Sorry to hear that! I’m not quite sure what may be causing these issues, as audio is loaded by Godot, and not any code I wrote, but what I can recommend is either converting your audios to different extensions (as they may work nicer with Godot) or checking hardware compatibility (although I’m not too sure about that one).
As for your ideas regarding contact, that sounds pretty interesting! I’ll see if I can add any contact info here or in my profile page.
