|
* Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit |
|
* Version: 0.0.25 |
|
* |
|
* 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. |
|
* 0.0.24 |
|
* Add support for mute control on SB Live 24bit (cards w/ SPI DAC) |
|
* 0.0.25 |
|
* Powerdown SPI DAC channels when not in use |
|
