This didn’t use to be the case, but now I can’t get Dorico (or Sibelius either) to play through my headphone jack. With the headphone plugged in, and the Mac OS 15.1.1 Sound Settings set to headphone jack, Dorico still plays through my computer speakers, even while ALL other sound output on the Mac plays through the phones just fine.
Set to: “Studio Display Speakers”.
But with my display in portrait mode, default sound goes through my Mac Studio Pro instead.
Make sure your headphones are plugged in before starting Dorico. Then, if all is well, you can select them from the dropdown labeled ASIO Driver, Close, Apply.
Like many professional audio software, Dorico does not automatically follow the system settings.
