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.

http://lists.linuxaudio.org/listinfo/linux-audio-user I mean feature, that if
firewire device is off, jack should switch to alsa - like it switches to dummy on
suspend.
