The attached file was created in Dorico 2.2.20. I can’t get any sound from it. The keyboard keys in HSSE’s GUI move during playback, so it’s receiving MIDI. And the metronome click works.
I tried switching the playback template to silence, clicking Apply, and then re-selecting HSSE+Pro and clicking Apply, as Ulf suggested in a thread a while back, but that had no effect. I haven’t touched anything in the mixer.
I closed this file and opened a few other Dorico files and they played back without issue. So the playback engine appears to be fine.
