+ *                   Cirrus Logic, Inc.
+ *  Routines for control of Cirrus Logic CS461x chips
+ *
+ *  KNOWN BUGS:
+ *    - Sometimes the SPDIF input DSP tasks get's unsynchronized
+ *      and the SPDIF get somewhat "distorcionated", or/and left right channel
+ *      are swapped. To get around this problem when it happens, mute and unmute 
+ *      the SPDIF input mixer control.
+ *    - On the Hercules Game Theater XP the amplifier are sometimes turned
+ *      off on inadecuate moments which causes distorcions on sound.
+ *
+ *  TODO:
+ *    - Secondary CODEC on some soundcards
+ *    - SPDIF input support for other sample rates then 48khz
+ *    - Posibility to mix the SPDIF output with analog sources.
+ *    - PCM channels for Center and LFE on secondary codec
+ *
+ *  NOTE: with CONFIG_SND_CS46XX_NEW_DSP unset uses old DSP image (which
+ *        is default configuration), no SPDIF, no secondary codec, no
+ *        multi channel PCM.  But known to work.
+ *
+ *  FINALLY: A credit to the developers Tom and Jordan 
+ *           at Cirrus for have helping me out with the DSP, however we
+ *           still don't have sufficient documentation and technical
+ *           references to be able to implement all fancy feutures
+ *           supported by the cs46xx DSP's.
