plughw is an alsa device that makes sure the hardware gets data in a 
format it can use.  It doesn't include dmix, an automatic mixer
that adjusts the sample rate to match what the card can process.  As 
near as I can tell, the default device is plughw with dmix added.
The hw device is the raw hardware, though it seems it is sometimes used 
as a synonym for plughw.  That means you are responsible
for all conversions to match the data the card can use internally.

I think it would be a good idea.  Many many changes have been made to 
alsa since 1.0.14.  The beta versions of 1.0.17 are
in circulation right now.  Do everything, not just pieces.  Including 
the drivers.
