When I run jack without sudo, I get this:

 jackd -R -d freebob -p128
jackd 0.102.20

loading driver ..
Freebob using Firewire port 0, node -1
Ieee1394Service::initialize: Could not get 1394 handle: Permission

Is ieee1394 and raw1394 driver loaded?
Fatal (devicemanager.cpp)[68] initialize: Could not initialize

Fatal (freebob.cpp)[69] freebob_new_handle: Could not initialize device

FreeBoB ERR: FREEBOB: Error creating virtual device

I guess I have a permissions problem of some sort.  When I was running a
packaged jack, I was able to run as non-root.  Can you advise?
