Looks like nice.
Mixer outputs are muted a priori; probably this is effectively the case
for the default settings; whatever, it can be changed easily by the user
using ffado-mixer.
Being unsure for mid rate is not indeed a real problem, it might be
corrected in the future, since the setupDefaultRouterConfig_...()
functions are for a very first initialization.

What does say the MAudio doc ? Concerning Focusrite Saffire and Presonus
Firestudio, they are mentionned to work up to 96kHz. Documentation I
read concerning DICE Jr chip mention it works up to 192kHz, but it is
not clear that the configuration of the rom remains similar in that
case.
Also I don't know to which extent the streaming protocol remains
similar.

Well, it seems you don't need any more help for using such outputs :-)
So there is no need for this, I think.

I imagined you tested everything using ffado-mixer, so I think your
changes can be commited in ffado trunk (I will just check for
compilation).

I didn't see rapidly how to download a patch version of your changes.
Could you send me the corresponding patches (git format-patch ...), I
will commit them into ffado trunk for you ?

Best regards,

Phil
