I cannot get active inputs with my Fast Track.
But jack got this:

Is that the problem? What that means?

I suspect you are not a member of the "audio" group. I suggest running the realTimeConfigQuickScan.pl script you find here: http://wiki.linuxmusicians.com/doku.php?id=system_configuration . See also the section on audio group on the page.
