I have a fresh instalation of supercollider 3.10.0. When I run:

s.boot;
{ [SinOsc.ar(440, 0, 0.2), SinOsc.ar(442, 0, 0.2)] }.play;

I should hear something right? But I hear no sound, while all other sounds apps do have sound. I tried this solution: No sound from SuperCollider with Jack2 but it didn't work for me. What can I do to find the problem?

My log says

Booting server 'localhost' on address 127.0.0.1:57110.

Is there anything suspicious? Thank you!

  • Are you able to hear sound from other jack apps? When you open the graph in qjackctl and boot supercollider, is Supercollider connected to your system output? – Les_h Aug 09 '21 at 18:06

    I had an linux xubuntu installation and everything was connected. Now I have installed linux mint and it works out of the box. – Philip Bergwerf Aug 25 '21 at 19:11
