So the bug has been fixed on the alsa-side. However, when I start jack via:
wfs@wfs16:~$ jackd -p 1024 -d alsa -C madifx_record_all -P madifx_playback_all

The corresponding cpp-file at that line compares against a variable
called "DRIVER_PORT_NUM", which is a constant defined in
"common/JackConstants.h" on line 53 on the github repo. Could that be
the problem?

For combining the MADI FX cards to one virtual

You can (and probably should) ask this again on the ALSA ML if you want
to do it via ALSA virtual devices. The other option is to have jack open
both cards:

I have never tried it, but in theory, you just add -A 2ndALSAname to the
command line and be done.
Not sure how much documentation is available for this on the internet,
but might be worth trying.
