I built a new PC and installed Ubuntu Studio 16.04.

The PC has a firewire card.

lsmod | grep fire
firewire_ohci          40960  0
firewire_core          65536  1 firewire_ohci
crc_itu_t              16384  1 firewire_core

ffado-diag claims these aren't there:

   libraw1394 ....
   libavc1394 ....
   libiec61883 ...
   libxml++-2.6 .

But, apt says they are.

jack_control fails to start the server if the firewire driver is selected.
But, starts ok if alsa is selected.

Not sure where to go from here. Any ideas/pointers appreciated.

My last 3 PC's, UBS 16.04, firewire, jack, just worked OOTB.
