sound fixes for 3.16-rc3

Browse source 
Here includes a few patchset for fixing mostly HD-audio issues in
 addition to a patch assuring the compress API bytes alignment and a
 fix for the die-hard existing race condition at USB-audio
 disconnection.  The volume looks big in Realtek HD-audio code, but
 it's just a translation of the fixup tables, and the actual changes
 are rather trivial.
