1. A lot of the "real-time kernel" aka "low-latency kernel" work happens at Stanford University's CCRMA lab. Their home page is http://ccrma.stanford.edu/planetccrma/software/. 2. For JACK there are some things you may need to do: a. Install jack-audio-connection-kit-devel and qjackctl. Qjackctl is a plugboard / patch panel for various devices and audio sources / sinks. It's mainly a GUI but IIRC there is a command line / config file interface too. b. Add the user to *both* the 'jackuser' and 'audio' groups. Otherwise you need to be 'root' to use JACK. -- desktop mailing list desktop@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/desktop
