+ * Copyright (c) 2004 James Courtier-Dutton <James@superbug.demon.co.uk>
+ * Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit
+ * Version: 0.0.25
+ *
+ * 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
+ *
+ * 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
