* 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.
