No Sonic Pi audio via built-in audio output

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.

  1. Be sure to launch Sonic-Pi again everytime you change something in your audio options.
  2. 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.
  3. 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.
