Using the latest version of Sonic Pi on Mac OS 10.14 Mojave, but not hearing audio via the built-in audio output jack. This only occurs with Sonic Pi, not other apps like iTunes. However, I can’t replicate it on other machines with the same software versions.
- Be sure to launch Sonic-Pi again everytime you change something in your audio options.
- I don’t know if it can help but sometimes useful to debug SuperCollider audio problems : check that you audio-in rate matches with the audio-ouput rate (44.100, 24 bits). To do so, check MIDI options on your Mac. For some reason, there is audio options in there too.
- If you put your computer to sleep and then use Sonic-Pi again, such a behavior can happen. Try to relaunch the software every time you can.
