7 * FEATURES currently supported:
8 * Output fixed at S32_LE, 2 channel to hw:0,0
9 * Rates: 44.1, 48, 96, 192.
13 * Use separate card based buffer for periods table.
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.
19 * Fixed missed interrupts.
21 * Add Sound card model number and names.
22 * Add Analog volume controls.
24 * Corrected playback interrupts. Now interrupt per period, instead of half period.
26 * Use single trigger for multichannel.
28 * Mic capture now works at fixed: S32_LE, 96000Hz, Stereo.
30 * Force buffer_size / period_size == INTEGER.
32 * Update p16v.c to work with changed alsa api.
34 * Update p16v.c to work with changed alsa api. Removed boot_devs.
36 * Merging with snd-emu10k1 driver.
38 * One stereo channel at 24bit now works.
40 * Added better register defines.
42 * Integrated with snd-emu10k1 driver.
44 * Removed #if 0 ... #endif
46 * Implement different capture rates.
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.
53 * Include capture buffer sizes.
56 * Some stability problems when unloading the snd-p16v kernel module.
61 * Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz.
62 * Currently capture fixed at 48000Hz.
67 * P16V Chip: CA0151-DBS
68 * Audigy 2 Chip: CA0102-IAT
69 * AC97 Codec: STAC 9721
70 * ADC: Philips 1361T (Stereo 24bit)
71 * DAC: CS4382-K (8-channel, 24bit, 192Khz)
