Why no sound?

Why is there no sound in this file; in fact, in all my Dorico files? Is it because I was trying to understand Playback Templates and messed something up? Thanks – Bill

It plays fine for me.

Check to make sure that you have playback enabled for this project while it’s open. This icon in the transport toolbar should be blue, like this.

Thanks. Yes, the button is blue. Restarted Dorico and rebooted the Mac but still no joy. Sound works everywhere else: Finale, Apple Music, etc. – Bill

By golly, I figured it out. Good work for an old man, don’t you think? Somehow the output box here got unchecked. Not me for sure; maybe my grandchildren. ::: Bill
