thank you for your request! For finding the source of the issues, it would be great if you could provide the following detailed information to nail the problem down:
1. How did you define the source url of the Image? Did you define it with a relative path like “../img/box.png”?
2. In which demo or examples project does the sound not work (i.e. which sound file exactly? is it a .wav, or .mp3?). Does the sound only not work with the cocosRenderer, or also with QmlRenderer?
