|
|
* 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.

|
|
* 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.

|
* Fix AC3 output.
|
|
* Enable S32_LE format support.
|
|
* 0.0.10

|
|
* 0.0.11
|
|
* Add Model name recognition.
|
|
* 0.0.12
|
|
