Dear Joachim, dear list,
indeed I have currently a couple of questions regarding Jack and as you are asking for them (which I do appreciate a lot), here they are:
- what is the "Transport" button in JackCtl for and do I have to press it in order to get output - or just the "start" button to launch jack? Actually I do not get any output no matter what I do
- Why does blue (current version) hang, as long Jack is active no matter if I have chosen Jack as a realtime-output device in the options or use -+rtaudio=jack in the commandline to overwrite the general blue realtime-prefereces settings? A dummy-rt-driver is chosen then, but not jack. As soon as I stop jack, blue reacts again. No sound either way...
- Why cant I choose Jack in the real-time configuration in CsoundQt0.9.6-1? If I choose Alsa, CsoundQt hangs as long as Jack is active. I do get still no output there when I specify it in the commandline-options with -odac -+rtaudio=jack. At least, CsoundQt is not hanging then while Jack is active. What am I missing?
- Is it generally possible to send 16 chnls in realtime from Csound to another application running and receive 22 chnls back from it in the same Csound-instrument, although I only have a stereo-soundcard on this machine?
I read the Csound manual and the Jack faq document but still do not get it to work. All my questions here refer to my Linux-System: Ubuntu 20.04.3 and current Version of Jack 1 (0.125.0rc1) and QjackCtl 0.5.0 installed, Csound 6.17 compiled yesterday from git.
