Hello,

It seems explanation of design of the avs-driver had some shortcomings. 
The AVS people (like me) are to blame for this :S

The exact opposite is true - we do not want 1:N component:card relation. 
Separate set of components and a separate card (machine board) per 
logically separate audio device is the approach of choice here. It has 
its benefits of simplifying PM and allowing for better user experience - 
probe() failure of one device does not prevent other devices from 
enumerating.
