Can you construct a ticket on http://subversion.ffado.org according to 
the instructions in FFADO's README such that we can take a look at it.

I personally think it has something to do with jackmp's FFADO backed not 
enabling the ports correctly. Since rc1 we actually disable processing 
for ports that are marked to be disabled. It could be that jackmp fails 
to enable the port for some reason.
