How to hear ambient sound when playing sequencer?

Hi all!
I recently move my project from 4.11 to . I had a simple Matinee cinematic with a camera move + music + animated character. In the level I have an AmbientSound with a sound cue with loop, no attenuation and AutoActivate flag.
When I play, or if I use the Matinee to play the cinematic, everything work as expected. If I use the new Sequencer, the AmbientSound is not played. I cannot hear it…
I could add the sound to the Sequencer Audio line (when I do, it works) but the less is the best :slight_smile: and it is working
with Matinee so it looks like a bug, isn’t it?

Thanks for your help!

I have the same problem
