+ * Abramo Bagnara <abramo@alsa-project.org>
+ * 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.
