3 * Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit
6 * FEATURES currently supported:
7 * Front, Rear and Center/LFE.
8 * Surround40 and Surround51.
9 * Capture from MIC an LINE IN input.
10 * SPDIF digital playback of PCM stereo and AC3/DTS works.
11 * (One can use a standard mono mini-jack to one RCA plugs cable.
12 * or one can use a standard stereo mini-jack to two RCA plugs cable.
13 * Plug one of the RCA plugs into the Coax input of the external decoder/receiver.)
14 * ( In theory one could output 3 different AC3 streams at once, to 3 different SPDIF outputs. )
15 * Notes on how to capture sound:
16 * The AC97 is used in the PLAYBACK direction.
17 * The output from the AC97 chip, instead of reaching the speakers, is fed into the Philips 1361T ADC.
18 * So, to record from the MIC, set the MIC Playback volume to max,
19 * unmute the MIC and turn up the MASTER Playback volume.
20 * So, to prevent feedback when capturing, minimise the "Capture feedback into Playback" volume.
22 * The only playback controls that currently do anything are: -
30 * For capture from Mic in or Line in.
31 * Digital/Analog ( switch must be in Analog mode for CAPTURE. )
33 * CAPTURE feedback into PLAYBACK
36 * Support interrupts per period.
37 * Removed noise from Center/LFE channel when in Analog mode.
38 * Rename and remove mixer controls.
40 * Use separate card based DMA buffer for periods table list.
42 * Change remove and rename ctrls into lists.
44 * Try to fix capture sources.
47 * Enable S32_LE format support.
49 * Enable playback 48000 and 96000 rates. (Rates other that these do not work, even with "plug:front".)
51 * Add Model name recognition.
53 * Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period.
54 * Remove redundent "voice" handling.
56 * Single trigger call for multi channels.
58 * Set limits based on what the sound card hardware can do.
59 * playback periods_min=2, periods_max=8
60 * capture hw constraints require period_size = n * 64 bytes.
61 * playback hw constraints require period_size = n * 64 bytes.
65 * Implement 192000 sample rate.
67 * Add support for SB0410 and SB0413.
69 * Modified Copyright message.
71 * Finally fix support for SB Live 24 bit. SB0410 and SB0413.
72 * The output codec needs resetting, otherwise all output is muted.
74 * Merge "pci_disable_device(pci);" fixes.
76 * Add 4 capture channels. (SPDIF only comes in on channel 0. )
77 * Add SPDIF capture using optional digital I/O module for SB Live 24bit. (Analog capture does not yet work.)
79 * Add support for MSI K8N Diamond Motherboard with onboard SB Live 24bit without AC97. From kiksen, bug #901
81 * Implement support for Line-in capture on SB Live 24bit.
84 * Some stability problems when unloading the snd-ca0106 kernel module.
88 * 4 Capture channels, only one implemented so far.
89 * Other capture rates apart from 48khz not implemented.
94 * P17 Chip: CA0106-DAT
95 * AC97 Codec: STAC 9721
96 * ADC: Philips 1361T (Stereo 24bit)
97 * DAC: WM8746EDS (6-channel, 24bit, 192Khz)
101 * P17 Chip: CA0106-DAT
103 * ADC: WM8775EDS (4 Channel)
104 * DAC: CS4382 (114 dB, 24-Bit, 192 kHz, 8-Channel D/A Converter with DSD Support)
105 * SPDIF Out control switches between Mic in and SPDIF out.
106 * No sound out or mic input working yet.
110 * P17 Chip: CA0106-DAT
114 * Trying to handle it like the SB0410.
