commit cb1fd837d93fbc495eab4aa3efaf8072937ff2df
Author: Takashi Iwai <tiwai@suse.de>
Date:   Wed Nov 19 14:59:03 2008 +0100

Add linear plugin wrapping iec958 PCM for ice1724-based boards
    
    The ice1724-based cards can handle only 32bit while the apps almost
    expet 16bit format for SPDIF I/O.  This prevents the default config
    working on many apps like mplayer, xine, etc.
    
    This patch simply adds the least automatic conversion by linear plugin.
    Note that "plug" isn't used here.  Otherwise we get a problem of the
    routing (plug over plug is buggy).
