4 | * Driver p16v chips | |
5 | * Version: 0.21 | |
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 | * Split from p16v.c | |
43 | * | |
1da177e4 LT |
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. | |
