I think that currently it is not used other that like an device ID, since all 
the hw audio devices, like
that hda-duplex use the global audiodev, like before the patches that added the 
audiodev in first place.

However there are patches under review that will allow hw audio devices select 
which
audiodev to use, even expose multiple audio devices this way 
(why not to have a hda controller, with two codecs attached? :-)
