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