The Sibelius Forum

About 4 weeks ago Sibelius would only playback through my Mac speakers. Prior to that I could listen to my Sibelius creations through my headphones which ar connected to Audiobox USB by PreSonus. I could also listen with my powered monitor speakers which are also connected to my PreSonus Audiobox USB. When Sibelius loads up, you can hear the sound coming out of my headphones. Yet when I work on the file I just pulled up, the sound only comes out of the built in MAC speakers and not the headphones. IS there a fix for this problem?

Hard to tell much without knowing more about your version of Sibelius or your Mac.
But in general, make sure you have the latest drivers for your Audiobox. Then you might want to check in Sound devices in your mac, that the audiobox is recognized. Do the same in Audio Engine Options in Sibelius. Then restart your Mac.
Better yet, make sure everything works without the Audiobox. Fix thing there first, then plug in the Audiobox and reset as needed.
