Now interrupt per period, instead of half period. * 0.13 * Use single trigger for multichannel. * 0.14 * Mic capture now works at fixed: S32_LE, 96000Hz, Stereo. * 0.15 * Force buffer_size / period_size == INTEGER. * 0.16 * Update p16v.c to work with changed alsa api. * 0.17 * Update p16v.c to work with changed alsa api. Removed boot_devs. * 0.18 * Merging with snd-emu10k1 driver. * 0.19 * One stereo channel at 24bit now works. * 0.20 * Added better register defines. * 0.21 * Integrated with snd-emu10k1 driver. * 0.22 * Removed #if 0 ... #endif * 0.23 * Implement different capture rates. * 0.24 * Implement different capture source channels. * e.g. When HD Capture source is set to SPDIF, * setting HD Capture channel to 0 captures from CDROM digital input. * setting HD Capture channel to 1 captures from SPDIF in. * 0.25 * Include capture buffer sizes. * * BUGS: * Some stability problems when unloading the snd-p16v kernel module. * -- * * TODO: * SPDIF out. * Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz. * Currently capture fixed at 48000Hz. * * -- * GENERAL INFO: * Model: SB0240 * P16V Chip: CA0151-DBS * Audigy 2 Chip: CA0102-IAT * AC97 Codec: STAC 9721 * ADC: Philips 1361T (Stereo 24bit) * DAC: CS4382-K (8-channel, 24bit, 192Khz) * * This code was initially based on code from ALSA's emu10k1x.c which is: * Copyright (c) by Francisco Moraes */ #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include "p16v.h" #define SET_CHANNEL 0 /* Testing channel outputs 0=Front, 1=Center/LFE, 2=Unknown, 3=Rear */ #define PCM_FRONT_CHANNEL 0 #define PCM_REAR_CHANNEL 1 #define PCM_CENTER_LFE_CHANNEL 2 #define PCM_SIDE_CHANNEL 3 #define CONTROL_FRONT_CHANNEL 0 #define CONTROL_REAR_CHANNEL 3 #define CONTROL_CENTER_LFE_CHANNEL 1 #define CONTROL_SIDE_CHANNEL 2 /* Card IDs: * Class 0401: 1102:0004 (rev 04) Subsystem: 1102:2002 -> Audigy2 ZS 7.1 Model:SB0350 * Class 0401: 1102:0004 (rev 04) Subsystem: 1102:1007 -> Audigy2 6.1 Model:SB0240 * Class 0401: 1102:0004 (rev 04) Subsystem: 1102:1002 -> Audigy2 Platinum Model:SB msb0240230009266 * Class 0401: 1102:0004 (rev 04) Subsystem: 1102:2007 -> Audigy4 Pro Model:SB0380 M1SB0380472001901E * */ /* hardware definition */ static const struct snd_pcm_hardware snd_p16v_playback_hw = { .info = SNDRV_PCM_INFO_MMAP | SNDRV_PCM_INFO_INTERLEAVED | SNDRV_PCM_INFO_BLOCK_TRANSFER | SNDRV_PCM_INFO_RESUME | SNDRV_PCM_INFO_MMAP_VALID | SNDRV_PCM_INFO_SYNC_START, .formats = SNDRV_PCM_FMTBIT_S32_LE, /* Only supports 24-bit samples padded to 32 bits. */ .rates = SNDRV_PCM_RATE_192000 | SNDRV_PCM_RATE_96000 | SNDRV_PCM_RATE_48000 | SNDRV_PCM_RATE_44100, .rate_min = 44100, .rate_max = 192000, .channels_min = 8, .channels_max = 8, .buffer_bytes_max = ((65536 - 64) * 8), .period_bytes_min = 64, .period_bytes_max = (65536 - 64), .periods_min = 2, .periods_max = 8, .fifo_size = 0, };
