2 * Copyright (c) by James Courtier-Dutton <James@superbug.demon.co.uk>
3 * Driver p16v chips
4 * Version: 0.21
5 *
6 * FEATURES currently supported:
7 * Output fixed at S32_LE, 2 channel to hw:0,0
8 * Rates: 44.1, 48, 96, 192.
9 *
10 * Changelog:
11 * 0.8
12 * Use separate card based buffer for periods table.
13 * 0.9
14 * Use 2 channel output streams instead of 8 channel.
15 * (8 channel output streams might be good for ASIO type output)
16 * Corrected speaker output, so Front -> Front etc.
17 * 0.10
18 * Fixed missed interrupts.
19 * 0.11
20 * Add Sound card model number and names.
21 * Add Analog volume controls.
22 * 0.12
23 * Corrected playback interrupts. Now interrupt per period, instead of half period.
24 * 0.13
25 * Use single trigger for multichannel.
26 * 0.14
27 * Mic capture now works at fixed: S32_LE, 96000Hz, Stereo.
28 * 0.15
29 * Force buffer_size / period_size == INTEGER.
30 * 0.16
31 * Update p16v.c to work with changed alsa api.
32 * 0.17
33 * Update p16v.c to work with changed alsa api. Removed boot_devs.
34 * 0.18
35 * Merging with snd-emu10k1 driver.
36 * 0.19
37 * One stereo channel at 24bit now works.
38 * 0.20
39 * Added better register defines.
40 * 0.21
41 * Split from p16v.c
42 *
43 *
44 * BUGS:
45 * Some stability problems when unloading the snd-p16v kernel module.
46 * --
47 *
48 * TODO:
49 * SPDIF out.
50 * Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz.
51 * Currently capture fixed at 48000Hz.
