The big question here would be why these widgets need to be added - the default thing is that all inputs and outputs are enabled so it can't be that and as you say callbacks are going to need to be added. If this is used then it probably makes sense for the card to set the fully routed flag since one possible use is to disable unconnected pins on the CODEC. > +- simple-sudio-card,widgets : The name of the audio card off-CODEC widgets. simple-audio-card.

One interesting thing here is that this is done separately to the card itself. Is there any actual dependency on the simple card, could this be made into a generic library that any machine driver could use? I can see other machines being able to make use of this.
