| * Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit |
| * Version: 0.0.23 |
| * |
| * FEATURES currently supported: |
| * Front, Rear and Center/LFE. |
| * Surround40 and Surround51. |
| * Capture from MIC an LINE IN input. |
| * SPDIF digital playback of PCM stereo and AC3/DTS works. |
| * (One can use a standard mono mini-jack to one RCA plugs cable. |
| * or one can use a standard stereo mini-jack to two RCA plugs cable. |
| * Plug one of the RCA plugs into the Coax input of the external decoder/receiver.) |
| * ( In theory one could output 3 different AC3 streams at once, to 3 different SPDIF outputs. ) |
| * Notes on how to capture sound: |
| * The AC97 is used in the PLAYBACK direction. |
| * The output from the AC97 chip, instead of reaching the speakers, is fed into the Philips 1361T ADC. |
| * So, to record from the MIC, set the MIC Playback volume to max, |
| * unmute the MIC and turn up the MASTER Playback volume. |
| * So, to prevent feedback when capturing, minimise the "Capture feedback into Playback" volume. |
| * |
| * The only playback controls that currently do anything are: - |
| * Analog Front |
| * Analog Rear |
| * Analog Center/LFE |
| * SPDIF Front |
| * SPDIF Rear |
| * SPDIF Center/LFE |
| * |
| * For capture from Mic in or Line in. |
| * Digital/Analog ( switch must be in Analog mode for CAPTURE. ) |
| * |
| * CAPTURE feedback into PLAYBACK |
| * |
| * Changelog: |
| * Support interrupts per period. |
| * Removed noise from Center/LFE channel when in Analog mode. |
| * Rename and remove mixer controls. |
| * 0.0.6 |
| * Use separate card based DMA buffer for periods table list. |
| * 0.0.7 |
| * Change remove and rename ctrls into lists. |
| * 0.0.8 |
| * Try to fix capture sources. |
| * 0.0.9 |
| * Fix AC3 output. |
| * Enable S32_LE format support. |
| * 0.0.10 |
| * Enable playback 48000 and 96000 rates. (Rates other that these do not work, even with "plug:front".) |
| * 0.0.11 |
| * Add Model name recognition. |
| * 0.0.12 |
| * Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period. |
| * Remove redundent "voice" handling. |
| * 0.0.13 |
| * Single trigger call for multi channels. |
| * 0.0.14 |
| * Set limits based on what the sound card hardware can do. |
| * playback periods_min=2, periods_max=8 |
| * capture hw constraints require period_size = n * 64 bytes. |
| * playback hw constraints require period_size = n * 64 bytes. |
| * 0.0.15 |
| * Minor updates. |
| * 0.0.16 |
| * Implement 192000 sample rate. |
| * 0.0.17 |
| * Add support for SB0410 and SB0413. |
| * 0.0.18 |
| * Modified Copyright message. |
| * 0.0.19 |
| * Finally fix support for SB Live 24 bit. SB0410 and SB0413. |
| * The output codec needs resetting, otherwise all output is muted. |
| * 0.0.20 |
| * Merge "pci_disable_device(pci);" fixes. |
| * 0.0.21 |
| * Add 4 capture channels. (SPDIF only comes in on channel 0. ) |
| * Add SPDIF capture using optional digital I/O module for SB Live 24bit. (Analog capture does not yet work.) |
| * 0.0.22 |
| * Add support for MSI K8N Diamond Motherboard with onboard SB Live 24bit without AC97. From kiksen, bug #901 |
| * 0.0.23 |
| * Implement support for Line-in capture on SB Live 24bit. |
| * |
| * BUGS: |
| * Some stability problems when unloading the snd-ca0106 kernel module. |
| * -- |
| * |
| * TODO: |
| * 4 Capture channels, only one implemented so far. |
| * Other capture rates apart from 48khz not implemented. |
| * MIDI |
