No Playback

I seem to have lost playback in Dorico 3 and Catalina. Noteperformer loads and is shown as the template but when I click play all I get is a solid green line and nothing happens. This happens in Dorico 2 as well so something in system seems not to work. I have attached screen shot.

Sorted! Deleted Dorico 3 and new install anti works fine now.

Next time it happens, check the audio device in the preferences, there might be a problem with the sampling frequency, and simply toggling between 44.1kHZ and 48kHz (and back to 44.1kHz) could solve this.

Hey tubagirl63, how did you delete Dorico 3?

Did you just drag the programme from Applications to the bin or did you remove extra folders from the Library folder etc.
