I’ve just installed Dorico Pro 3.5. The instruction videos in the Hub play but without sound. They do play with sound on YouTube (but not if the YouTube button is pressed in 3.5; I have to call up YouTube from outside 3.5.) The music I’ve created in Dorico 3.1 and (so far) in 3.5 plays just fine, so the sound problem seems to be special to the videos. No big deal…but is this soundless video problem special to my setup?
