Not sure I understand the question fully. If you are using JACK-based apps, you will always want JACK running, whichever audio device is available. If your apps don't require JACK, then why bother to use it? It sounds like you want some facility to run JACK under certain conditions. I believe there are some hooks in udev that will let you run a script, for example when a firewire device is plugged in. That script could start jackd. You don't mention the type of app; if it's a recorder/player/mixer thing, Nama (based on Ecasound) automatically *detects* JACK, falling back to ALSA if necessary. cheers, -- Joel Roth _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
