That's not true.  The ffado tools (the mixer, the discovery & diagnostic 
tools, etc) work fine whether or not the alsa module is loaded, and 
whether or not jack is running on the device.  The problem with the AF12 
and your driver was whatever the problem is with ffado and AF firmware > 
4.8.  Somehow the Clemens snd-fireworks driver was unaffected.  I dont 
know enough about the driver and hardware to understand why, but I'm 
sure you will figure it out.  I'm glad to see progress on this driver so 
do not hesitate to ask for anything.

Alsamixer successfully changes SR and clock source.  I started jack and 
played back and edited an ardour session with no problems.  As you said 
earlier, capture doesn't work.  the ports are there but no signal.  Once 
that works Ill start using this driver full time.
