2 * Copyright (c) by Jaroslav Kysela <perex@suse.cz>
3 * Abramo Bagnara <abramo@alsa-project.org>
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 controll.
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.
