Thanks again. When I select the event Music in the Event Viewer window, and play it, it works well. So, I presume that the event works within Wwise ? The name is exactly the same as the event. In the capture log window, when I play the event music, I have all the notifications. (As I work with the lesson 2 of Wwise, I don't work with Unity). Finally, in the capture log windows, I have a lot of notifications, but not music event. I confirm that the music event exist in my soundbanks I've generated (when I select the music soundbank, the event music is in the Hierarchy Inclusion, like events in other soundbanks). My question may be stupid, but do you know if we can open doors in Cube ? Because, following the tutorial, the music begins to play when we open doors, but I don't see doors (only corridors).
