Right click in the upper part of the timeline, add destination marker.

I added a marker, but now it doesn’t seem to work when I play the sound in unreal with a “OnTimelineMarker” event…

Post a screenshot of your implementation. “OnTimelineMarker” is a callback ; are you using it correctly?

Maybe did you forgot the “Enable Timeline Callbacks” option.

In my exemple, it does display “Marker A” on screen, as it is in my event:
