* Copyright (c) 2004 James Courtier-Dutton <James@superbug.demon.co.uk>
|
|
* 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

|
* 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
|
|

|
|
* Implement support for Line-in capture on SB Live 24bit.
|
|
*
|
|
* BUGS:
|
|
* Some stability problems when unloading the snd-ca0106 kernel module.
