4 * Driver p16v chips
5 * Version: 0.25
6 *
7 * FEATURES currently supported:
8 * Output fixed at S32_LE, 2 channel to hw:0,0
9 * Rates: 44.1, 48, 96, 192.
10 *
11 * Changelog:
12 * 0.8
13 * Use separate card based buffer for periods table.
14 * 0.9
15 * Use 2 channel output streams instead of 8 channel.
16 * (8 channel output streams might be good for ASIO type output)
17 * Corrected speaker output, so Front -> Front etc.
18 * 0.10
19 * Fixed missed interrupts.
20 * 0.11
21 * Add Sound card model number and names.
22 * Add Analog volume controls.
23 * 0.12
24 * Corrected playback interrupts. Now interrupt per period, instead of half period.
25 * 0.13
26 * Use single trigger for multichannel.
27 * 0.14
28 * Mic capture now works at fixed: S32_LE, 96000Hz, Stereo.
29 * 0.15
30 * Force buffer_size / period_size == INTEGER.
31 * 0.16
32 * Update p16v.c to work with changed alsa api.
33 * 0.17
34 * Update p16v.c to work with changed alsa api. Removed boot_devs.
35 * 0.18
36 * Merging with snd-emu10k1 driver.
37 * 0.19
38 * One stereo channel at 24bit now works.
39 * 0.20
40 * Added better register defines.
41 * 0.21
42 * Integrated with snd-emu10k1 driver.
43 * 0.22
44 * Removed #if 0 ... #endif
45 * 0.23
46 * Implement different capture rates.
47 * 0.24
48 * Implement different capture source channels.
49 * e.g. When HD Capture source is set to SPDIF,
50 * setting HD Capture channel to 0 captures from CDROM digital input.
51 * setting HD Capture channel to 1 captures from SPDIF in.
52 * 0.25
53 * Include capture buffer sizes.
54 *
55 * BUGS:
56 * Some stability problems when unloading the snd-p16v kernel module.
57 * --
58 *
59 * TODO:
60 * SPDIF out.
61 * Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz.
62 * Currently capture fixed at 48000Hz.
63 *
