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. |

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. |

64 | * Minor updates. |
65 | * 0.0.16 |
66 | * Implement 192000 sample rate. |

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 |
