1 /*
2  *  Copyright (c) by James Courtier-Dutton <James@superbug.demon.co.uk>
3  *  Driver p16v chips
4  *  Version: 0.25
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  *    Integrated with snd-emu10k1 driver.
42  *  0.22
43  *    Removed #if 0 ... #endif
44  *  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.
51  *  0.25
52  *    Include capture buffer sizes.
53  *
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.
