Oh, and while alsamixer will allow the selection of the AF12, alsamixer
then says the AF12 has no controls.
So, to control the gains and such one has to figure out how to stop the
alsa control of the AF12 and then start ffado to make any changes?

Ouch!

That may mean that in your case not using the alsa drivers but using the
ffado drivers may make more sense. Ffado use is hopefully coming to
-controls soon. However, I would suggest that if alsa does not show the
controls available, then the alsa module should have a bug report against
it. Though to be honest, I do not know if the firewire protocol tells the
host what controls it has in the way that other audio devices do.
Anyway, if ffado-mixer actually works for you, I would like to know. I
know of at least one case where ffado-controls does not work with the alsa
fw modules.
Have I said "I don't know" enough? ;)

I have some firewire interfaces that I have not used for a while and when I
used them ffado was the thing.
If I get some time I could check how alsa supports them.
I have:
Focusrite Pro 40
Focusrite Pro 24 dsp
a few Presonus FP10s (no internal mixer or sw based controls if I remeber
correctly)
Fireface 800 (Have not used it)
Presonus Studiolive 16.4.2 (lots of controllers on that one)
Any of theses that are of particular interest ?

With current kernels, the Fireface 800 is supported by the ALSA drivers,
but no controls are exposed (through ffado-mixer you get full control
though) and it's also not possible to run it equally well as with FFADO
(e.g. only 512 frames, instead of 64 frames @48kHz).
This at least was my experience on a 5.0.7 Linux kernel, so I had to
blacklist the snd-fireface driver (otherwise you get very weird errors,
if you don't expect it ;-) ).
With no hardmix control and higher latencies, for that device the ALSA
driver doesn't seem to be a great solution (yet). FFADO works great
though.

Thanks.
That basically means the ff800 is pretty useless without ffado. Controlling
the matrix and onboard mixer and the rest of the features are a necessity
usually. If the latency is far worse, it is a deal breaker in itself.
