James Courtier-Dutton22bc30c2005-05-07 16:13:40 +02004 * Version: 0.25
Linus Torvalds1da177e2005-04-16 15:20:36 -07005 *
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 * Integrated with snd-emu10k1 driver.
42 * 0.22
43 * Removed #if 0 ... #endif
James Courtier-Duttonf927c8f2005-05-07 15:34:13 +020044 * 0.23
45 * Implement different capture rates.
46 * 0.24
47 * Implement different capture source channels.
48 * e.g. When HD Capture source is set to SPDIF,
49 * setting HD Capture channel to 0 captures from CDROM digital input.
50 * setting HD Capture channel to 1 captures from SPDIF in.
James Courtier-Dutton22bc30c2005-05-07 16:13:40 +020051 * 0.25
52 * Include capture buffer sizes.
Linus Torvalds1da177e2005-04-16 15:20:36 -070053 *
54 * BUGS:
55 * Some stability problems when unloading the snd-p16v kernel module.
56 * --
57 *
58 * TODO:
59 * SPDIF out.
60 * Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz.
61 * Currently capture fixed at 48000Hz.
