Sound fixes for 3.9-rc3 

A collection of small fixes, as expected for the middle rc:
 - A couple of fixes for potential NULL dereferences and out-of-range
   array accesses revealed by static code parsers
 - A fix for the wrong error handling detected by trinity
 - A regression fix for missing audio on some MacBooks
 - CA0132 DSP loader fixes
 - Fix for EAPD control of IDT codecs on machines w/o speaker
 - Fix a regression in the HD-audio widget list parser code
 - Workaround for the NuForce UDH-100 USB audio
