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. 30 * Benny <benny@hostmobility.com> 31 * 32 * This program is free software; you can redistribute it and/or modify 33 * it under the terms of the GNU General Public License as published by 34 * the Free Software Foundation; either version 2 of the License, or 35 * (at your option) any later version. 36 * 37 * This program is distributed in the hope that it will be useful, 38 * but WITHOUT ANY WARRANTY; without even the implied warranty of 39 * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
