James Courtier-Dutton 001f758990 [ALSA] Improve SPDIF playback via the P16V/CA0151 chip. 
EMU10K1/EMU10K2 driver
Although we can set 44100 as the output rate, the SPDIF can do it, but the Analog output cannot.
The SPDIF has the bug, whereby the Left channel arrives one sample late, so although we don't do any resampling,
it is not good for AC3 non-audio output.

* Copyright (c) by James Courtier-Dutton <James@superbug.demon.co.uk>
* Driver p16v chips
* Version: 0.22
*
* FEATURES currently supported:
* Output fixed at S32_LE, 2 channel to hw:0,0
* Rates: 44.1, 48, 96, 192.
*
* Changelog:
* 0.8
* Use separate card based buffer for periods table.
* 0.9
* Use 2 channel output streams instead of 8 channel.
* (8 channel output streams might be good for ASIO type output)
* Corrected speaker output, so Front -> Front etc.
* 0.10
* Fixed missed interrupts.
* 0.11
* Add Sound card model number and names.
* Add Analog volume controls.
* 0.12
* Corrected playback interrupts. Now interrupt per period, instead of half period.
* 0.13
* Use single trigger for multichannel.
* 0.14
* Mic capture now works at fixed: S32_LE, 96000Hz, Stereo.
* 0.15
* Force buffer_size / period_size == INTEGER.
* 0.16
* Update p16v.c to work with changed alsa api.
* 0.17
* Update p16v.c to work with changed alsa api. Removed boot_devs.
* 0.18
* Merging with snd-emu10k1 driver.
* 0.19
* One stereo channel at 24bit now works.
* 0.20
* Added better register defines.
* 0.21
* Integrated with snd-emu10k1 driver.
* 0.22
* Removed #if 0 ... #endif
*
*
* BUGS:
* Some stability problems when unloading the snd-p16v kernel module.
* --
*
* TODO:
* SPDIF out.
* Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz.
* Currently capture fixed at 48000Hz.
*
