3 * Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit
6 * FEATURES currently supported:
7 * See ca0106_main.c for features.
10 * Support interrupts per period.
11 * Removed noise from Center/LFE channel when in Analog mode.
12 * Rename and remove mixer controls.
14 * Use separate card based DMA buffer for periods table list.
16 * Change remove and rename ctrls into lists.
18 * Try to fix capture sources.
21 * Enable S32_LE format support.
23 * Enable playback 48000 and 96000 rates. (Rates other that these do not work, even with "plug:front".)
25 * Add Model name recognition.
27 * Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period.
28 * Remove redundent "voice" handling.
30 * Single trigger call for multi channels.
32 * Set limits based on what the sound card hardware can do.
33 * playback periods_min=2, periods_max=8
34 * capture hw constraints require period_size = n * 64 bytes.
35 * playback hw constraints require period_size = n * 64 bytes.
37 * Separate ca0106.c into separate functional .c files.
39 * Modified Copyright message.
41 * Add iec958 file in proc file system to show status of SPDIF in.
43 * Implement support for Line-in capture on SB Live 24bit.
45 * This code was initially based on code from ALSA's emu10k1x.c which is:
