+ *  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.
+ *
+ *    --
+ *  GENERAL INFO:
+ *    Model: SB0240
+ *    P16V Chip: CA0151-DBS

+ *  Copyright (c) by James Courtier-Dutton <James@superbug.demon.co.uk>
+ *  Driver p16v chips
+ *  Version: 0.21
+ *
+ *  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.

+/* Previously the voice allocator started at 0 every time.  The new voice 
+ * allocator uses a round robin scheme.  The next free voice is tracked in 
+ * the card record and each allocation begins where the last left off.  The 
+ * hardware requires stereo interleaved voices be aligned to an even/odd 
+ * boundary.  For multichannel voice allocation we ensure than the block of 
+ * voices does not cross the 32 voice boundary.  This simplifies the 
+ * multichannel support and ensures we can use a single write to the 
+ * (set|clear)_loop_stop registers.  Otherwise (for example) the voices would 
+ * get out of sync when pausing/resuming a stream.
