Hi, I'm using jack without any problems on most applications. But with csound by typing: csound -+rtaudio=jack -odac foo.csd I get no sound. The terminal output while realtime processing seems normal. Also qJackControl connection window shows no connection between csound outputs and system capture device. How can i make such connection. Thanx. -- Arda EDEN Cumhuriyet University Faculty of Fine Arts Department of Music Technology Sivas/TURKEY
