Edit: I accidentally put sound for the pause and resume in my recreation. They are all music in the actual project
Edit 2: Fixed! I changed it from music to sound and that did the trick
Music and sound have separate channels in GDevelop. And since at the beginning of the scene, a music starts playing, the other events must be pause/resume music on channel instead of sound.
If you’re pausing / resuming a music, the event looks fine. The only possible issue would be with the “paused” boolean. I’m guessing other events that are linked to the boolean are causing this issue.
Try removing the “paused” is true / false conditions, to check if the music will work properly after that.
