6 * FEATURES currently supported:
7 * Output fixed at S32_LE, 2 channel to hw:0,0
8 * Rates: 44.1, 48, 96, 192.
12 * Use separate card based buffer for periods table.
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.
18 * Fixed missed interrupts.
20 * Add Sound card model number and names.
21 * Add Analog volume controls.
23 * Corrected playback interrupts. Now interrupt per period, instead of half period.
25 * Use single trigger for multichannel.
27 * Mic capture now works at fixed: S32_LE, 96000Hz, Stereo.
29 * Force buffer_size / period_size == INTEGER.
31 * Update p16v.c to work with changed alsa api.
33 * Update p16v.c to work with changed alsa api. Removed boot_devs.
35 * Merging with snd-emu10k1 driver.
37 * One stereo channel at 24bit now works.
39 * Added better register defines.
41 * Integrated with snd-emu10k1 driver.
43 * Removed #if 0 ... #endif
47 * Some stability problems when unloading the snd-p16v kernel module.
52 * Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz.
53 * Currently capture fixed at 48000Hz.
58 * P16V Chip: CA0151-DBS
59 * Audigy 2 Chip: CA0102-IAT
60 * AC97 Codec: STAC 9721
61 * ADC: Philips 1361T (Stereo 24bit)
62 * DAC: CS4382-K (8-channel, 24bit, 192Khz)
