sound fixes for 3.17-rc7 (or final)

Browse Source 
One fix is about a buggy compuation in PCM API function Clemens
 spotted out, but the impact must be really small as no one
 really uses it in user-space side.  The rest are a trivial fix
 for a HD-audio model and a USB-audio device-specific regression
 fix, so all look fairly safe to apply.
