4  *                   Cirrus Logic, Inc.
5  *  Routines for control of Cirrus Logic CS461x chips
6  *
7  *  KNOWN BUGS:
8  *    - Sometimes the SPDIF input DSP tasks get's unsynchronized
9  *      and the SPDIF get somewhat "distorcionated", or/and left right channel
10  *      are swapped. To get around this problem when it happens, mute and unmute
11  *      the SPDIF input mixer control.
12  *    - On the Hercules Game Theater XP the amplifier are sometimes turned
13  *      off on inadecuate moments which causes distorcions on sound.
14  *
15  *  TODO:
16  *    - Secondary CODEC on some soundcards
17  *    - SPDIF input support for other sample rates then 48khz
18  *    - Posibility to mix the SPDIF output with analog sources.
19  *    - PCM channels for Center and LFE on secondary codec
20  *
21  *  NOTE: with CONFIG_SND_CS46XX_NEW_DSP unset uses old DSP image (which
22  *        is default configuration), no SPDIF, no secondary codec, no
23  *        multi channel PCM.  But known to work.
24  *
25  *  FINALLY: A credit to the developers Tom and Jordan
26  *           at Cirrus for have helping me out with the DSP, however we
27  *           still don't have sufficient documentation and technical
28  *           references to be able to implement all fancy feutures
29  *           supported by the cs46xx DSP's.
