Hearing playback

I am using Dorico Pro 3 for the first time and cannot hear playback on one of the sample projects (Rameau); the other sample projects sound ok. I also have imported an xml file of a piece I wrote and cannot hear playback on that. What am I doing wrong?

Welcome to the forum, fbrives. Did you definitely install the separate sounds/content installer as well as the application installer? If you choose Play > Playback Template and choose to re-apply the ‘HSSE+HSO (Pro)’ playback template in the projects that don’t play back, does that restore the sound?

That did the trick. Thanks! This probably won’t be my last dumb question…
