[Scummvm-cvs-logs] SF.net SVN: scummvm:[40936] scummvm/trunk/engines/sci/engine/ksound.cpp

Revision: 40936
          http://scummvm.svn.sourceforge.net/scummvm/?rev=40936&view=rev
Author:   thebluegr
Date:     2009-05-27 09:07:08 +0000 (Wed, 27 May 2009)

Log Message:
-----------
- Renamed the Audio commands to kSci*, from kSci1* (since they're pretty much the same for SCI1.1)
- Added enums for the audio sync cases
- Added a warning when kDoSync is called with the new semantics (SQ4CD or newer)
