4 * Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit
5 * Version: 0.0.25
6 *
7 * FEATURES currently supported:
8 * Front, Rear and Center/LFE.
9 * Surround40 and Surround51.
10 * Capture from MIC an LINE IN input.
11 * SPDIF digital playback of PCM stereo and AC3/DTS works.
12 * (One can use a standard mono mini-jack to one RCA plugs cable.
13 * or one can use a standard stereo mini-jack to two RCA plugs cable.
14 * Plug one of the RCA plugs into the Coax input of the external decoder/receiver.)
15 * ( In theory one could output 3 different AC3 streams at once, to 3 different SPDIF outputs. )
16 * Notes on how to capture sound:
17 * The AC97 is used in the PLAYBACK direction.
18 * The output from the AC97 chip, instead of reaching the speakers, is fed into the Philips 1361T ADC.
19 * So, to record from the MIC, set the MIC Playback volume to max,
20 * unmute the MIC and turn up the MASTER Playback volume.
21 * So, to prevent feedback when capturing, minimise the "Capture feedback into Playback" volume.
22 *
23 * The only playback controls that currently do anything are: -
24 * Analog Front
25 * Analog Rear
26 * Analog Center/LFE
27 * SPDIF Front
28 * SPDIF Rear
29 * SPDIF Center/LFE
30 *
31 * For capture from Mic in or Line in.
32 * Digital/Analog ( switch must be in Analog mode for CAPTURE. )
33 *
34 * CAPTURE feedback into PLAYBACK
35 *
36 * Changelog:
37 * Support interrupts per period.
38 * Removed noise from Center/LFE channel when in Analog mode.
39 * Rename and remove mixer controls.
40 * 0.0.6
41 * Use separate card based DMA buffer for periods table list.
42 * 0.0.7
43 * Change remove and rename ctrls into lists.
44 * 0.0.8
45 * Try to fix capture sources.
46 * 0.0.9
47 * Fix AC3 output.
48 * Enable S32_LE format support.
49 * 0.0.10
50 * Enable playback 48000 and 96000 rates. (Rates other that these do not work, even with "plug:front".)
51 * 0.0.11
52 * Add Model name recognition.
53 * 0.0.12
54 * Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period.
55 * Remove redundent "voice" handling.
56 * 0.0.13
57 * Single trigger call for multi channels.
58 * 0.0.14
59 * Set limits based on what the sound card hardware can do.
60 * playback periods_min=2, periods_max=8
61 * capture hw constraints require period_size = n * 64 bytes.
62 * playback hw constraints require period_size = n * 64 bytes.
63 * 0.0.15
64 * Minor updates.
65 * 0.0.16
66 * Implement 192000 sample rate.
67 * 0.0.17
68 * Add support for SB0410 and SB0413.
69 * 0.0.18
70 * Modified Copyright message.
71 * 0.0.19
72 * Finally fix support for SB Live 24 bit. SB0410 and SB0413.
73 * The output codec needs resetting, otherwise all output is muted.
74 * 0.0.20
75 * Merge "pci_disable_device(pci);" fixes.
76 * 0.0.21
77 * Add 4 capture channels. (SPDIF only comes in on channel 0. )
78 * Add SPDIF capture using optional digital I/O module for SB Live 24bit. (Analog capture does not yet work.)
79 * 0.0.22
80 * Add support for MSI K8N Diamond Motherboard with onboard SB Live 24bit without AC97. From kiksen, bug #901
81 * 0.0.23
82 * Implement support for Line-in capture on SB Live 24bit.
83 * 0.0.24
84 * Add support for mute control on SB Live 24bit (cards w/ SPI DAC)
85 * 0.0.25
86 * Powerdown SPI DAC channels when not in use
87 *
88 * BUGS:
89 * Some stability problems when unloading the snd-ca0106 kernel module.
90 * --
91 *
92 * TODO:
93 * 4 Capture channels, only one implemented so far.
94 * Other capture rates apart from 48khz not implemented.
