It's likely that the topology file does not contain all the widgets/dais 
required by the hard-coded routes the machine driver, and by becoming 
stricter warnings became errors which in turn prevent the card from 
being created. It may be that we have to define a backwards compatible 
behavior that's enabled only for Intel legacy cases.

Please post the results of alsa-info.sh somewhere so that we can take a 
look.
