3  * Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit
4  * Version: 0.0.25
5  *
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.
21  *
22  * The only playback controls that currently do anything are: -
23  * Analog Front
24  * Analog Rear
25  * Analog Center/LFE
26  * SPDIF Front
27  * SPDIF Rear
28  * SPDIF Center/LFE
29  *
30  * For capture from Mic in or Line in.
31  * Digital/Analog ( switch must be in Analog mode for CAPTURE. )
32  *
33  * CAPTURE feedback into PLAYBACK
34  *
35  * Changelog:
36  * Support interrupts per period.
37  * Removed noise from Center/LFE channel when in Analog mode.
38  * Rename and remove mixer controls.
39  * 0.0.6
40  * Use separate card based DMA buffer for periods table list.
41  * 0.0.7
42  * Change remove and rename ctrls into lists.
43  * 0.0.8
44  * Try to fix capture sources.
45  * 0.0.9
46  * Fix AC3 output.
47  * Enable S32_LE format support.
48  * 0.0.10
49  * Enable playback 48000 and 96000 rates. (Rates other that these do not work, even with "plug:front".)
50  * 0.0.11
51  * Add Model name recognition.
52  * 0.0.12
53  * Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period.
54  * Remove redundent "voice" handling.
55  * 0.0.13
56  * Single trigger call for multi channels.
57  * 0.0.14
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.
62  * 0.0.15
63  * Minor updates.
64  * 0.0.16
65  * Implement 192000 sample rate.
66  * 0.0.17
67  * Add support for SB0410 and SB0413.
68  * 0.0.18
69  * Modified Copyright message.
70  * 0.0.19
71  * Finally fix support for SB Live 24 bit. SB0410 and SB0413.
72  * The output codec needs resetting, otherwise all output is muted.
73  * 0.0.20
74  * Merge "pci_disable_device(pci);" fixes.
75  * 0.0.21
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.)
78  * 0.0.22
79  * Add support for MSI K8N Diamond Motherboard with onboard SB Live 24bit without AC97. From kiksen, bug #901
80  * 0.0.23
81  * Implement support for Line-in capture on SB Live 24bit.
82  * 0.0.24
83  * Add support for mute control on SB Live 24bit (cards w/ SPI DAC)
84  * 0.0.25
85  * Powerdown SPI DAC channels when not in use
86  *
87  * BUGS:
88  * Some stability problems when unloading the snd-ca0106 kernel module.
89  * --
90  *
91  * TODO:
92  * 4 Capture channels, only one implemented so far.
93  * Other capture rates apart from 48khz not implemented.
