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.
