(Rates other that these do not work, even with "plug:front".) * 0.0.11 * Add Model name recognition. * 0.0.12 * Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period. * Remove redundent "voice" handling. * 0.0.13 * Single trigger call for multi channels. * 0.0.14 * Set limits based on what the sound card hardware can do. * playback periods_min=2, periods_max=8 * capture hw constraints require period_size = n * 64 bytes. * playback hw constraints require period_size = n * 64 bytes. * 0.0.15 * Separated ca0106.c into separate functional .c files. * 0.0.16 * Modified Copyright message. * 0.0.17 * Implement Mic and Line in Capture. * 0.0.18 * Add support for mute control on SB Live 24bit (cards w/ SPI DAC) * * This code was initially based on code from ALSA's emu10k1x.c which is: * Copyright (c) by Francisco Moraes <[email protected]> */ #include <linux/delay.h> #include <linux/init.h> #include <linux/interrupt.h> #include <linux/moduleparam.h> #include <sound/core.h> #include <sound/initval.h> #include <sound/pcm.h> #include <sound/ac97_codec.h> #include <sound/info.h> #include <sound/tlv.h> #include <linux/io.h> #include "ca0106.h" static void ca0106_spdif_enable(struct snd_ca0106 *emu) { … } static void ca0106_set_capture_source(struct snd_ca0106 *emu) { … } static void ca0106_set_i2c_capture_source(struct snd_ca0106 *emu, unsigned int val, int force) { … } static void ca0106_set_capture_mic_line_in(struct snd_ca0106 *emu) { … } static void ca0106_set_spdif_bits(struct snd_ca0106 *emu, int idx) { … } /* */ static const DECLARE_TLV_DB_SCALE(snd_ca0106_db_scale1, -5175, 25, 1);
