3 * Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit
48510070 4 * Version: 0.0.25
1da177e4
LT		 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
7199acdc
JCD		 80 * 0.0.23
81 * Implement support for Line-in capture on SB Live 24bit.
b18cd538
TP		 82 * 0.0.24
83 * Add support for mute control on SB Live 24bit (cards w/ SPI DAC)
48510070
TP		 84 * 0.0.25
85 * Powerdown SPI DAC channels when not in use
1da177e4

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.
