Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 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. |

| 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. |

| 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 |

| 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 |
