Sound Mega-commit. Expect further cleanup until code freeze.
For a slightly thorough explaination, please refer to [1] http://people.freebsd.org/~ariff/SOUND_4.TXT.html .
Summary of changes includes:
1 Volume Per-Channel (vpc). Provides private / standalone volume control unique per-stream pcm channel without touching master volume / pcm. Applications can directly use SNDCTL_DSP_[GET|SET][PLAY|REC]VOL, or for backwards compatibility, SOUND_MIXER_PCM through the opened dsp device instead of /dev/mixer. Special "bypass" mode is enabled through /dev/mixer which will automatically detect if the adjustment is made through /dev/mixer and forward its request to this private volume controller. Changes to this volume object will not interfere with other channels.
Requirements: - SNDCTL_DSP_[GET|SET][PLAY|REC]_VOL are newer ioctls (OSSv4) which require specific application modifications (preferred). - No modifications required for using bypass mode, so applications like mplayer or xmms should work out of the box.
Kernel hints: - hint.pcm.%d.vpc (0 = disable vpc).
Kernel sysctls: - hw.snd.vpc_mixer_bypass (default: 1). Enable or disable /dev/mixer bypass mode. - hw.snd.vpc_autoreset (default: 1). By default, closing/opening /dev/dsp will reset the volume back to 0 db gain/attenuation. Setting this to 0 will preserve its settings across device closing/opening. - hw.snd.vpc_reset (default: 0). Panic/reset button to reset all volume settings back to 0 db. - hw.snd.vpc_0db (default: 45). 0 db relative to linear mixer value.
2 High quality fixed-point Bandlimited SINC sampling rate converter, based on Julius O'Smith's Digital Audio Resampling - http://ccrma.stanford.edu/~jos/resample/. It includes a filter design script written in awk (the clumsiest joke I've ever written) - 100% 32bit fixed-point, 64bit accumulator. - Possibly among the fastest (if not fastest) of its kind. - Resampling quality is tunable, either runtime or during kernel compilation (FEEDER_RATE_PRESETS). - Quality can be further customized during kernel compilation by defining FEEDER_RATE_PRESETS in /etc/make.conf.
Kernel sysctls: - hw.snd.feeder_rate_quality. 0 - Zero-order Hold (ZOH). Fastest, bad quality. 1 - Linear Interpolation (LINEAR). Slightly slower than ZOH, better quality but still does not eliminate aliasing. 2 - (and above) - Sinc Interpolation(SINC). Best quality. SINC quality always start from 2 and above.
Rough quality comparisons: - http://people.freebsd.org/~ariff/z_comparison/
3 Bit-perfect mode. Bypasses all feeder/dsp effects. Pure sound will be directly fed into the hardware.
4 Parametric (compile time) Software Equalizer (Bass/Treble mixer). Can be customized by defining FEEDER_EQ_PRESETS in /etc/make.conf.
5 Transparent/Adaptive Virtual Channel. Now you don't have to disable vchans in order to make digital format pass through. It also makes vchans more dynamic by choosing a better format/rate among all the concurrent streams, which means that dev.pcm.X.play.vchanformat/rate becomes sort of optional.
6 Exclusive Stream, with special open() mode O_EXCL. This will "mute" other concurrent vchan streams and only allow a single channel with O_EXCL set to keep producing sound.
Other Changes: * most feeder_* stuffs are compilable in userland. Let's not speculate whether we should go all out for it (save that for FreeBSD 16.0-RELEASE). * kobj signature fixups, thanks to Andriy Gapon <avg@freebsd.org> * pull out channel mixing logic out of vchan.c and create its own feeder_mixer for world justice. * various refactoring here and there, for good or bad. * activation of few more OSSv4 ioctls() (see [1] above). * opt_snd.h for possible compile time configuration: (mostly for debugging purposes, don't try these at home) SND_DEBUG SND_DIAGNOSTIC SND_FEEDER_MULTIFORMAT SND_FEEDER_FULL_MULTIFORMAT SND_FEEDER_RATE_HP SND_PCM_64 SND_OLDSTEREO
Manual page updates are on the way.

MFp4 (114068): Use bus_get_dma_tag() to obtain the parent DMA tag to make the drivers a little bit more non-ia32/amd64 friendly.
There is no man page for bus_get_dma_tag, so this is modelled after rev. 1.62 of src/sys/dev/sound/pci/es137x.c by marius.

Audio drivers failed to detect failure condition and attempted to assign DMA address to the wrong address. It can cause system lockup or other mysterious errors. Since most sound cards requires low DMA address(BUS_SPACE_MAXADDR_24BIT) sndbuf_alloc() would fail when the audio driver is loaded after long running of operations.

Rename the sound device drivers:
- `sound' The generic sound driver, always required.
- `snd_*' Device-dependent drivers, named after the sound module names. Configure accordingly to your hardware.
In addition, rename the `snd_pcm' module to `sound' in order to sync with the driver names.

The newpcm headers currently #define away INTR_MPSAFE and INTR_TYPE_AV because they bogusly check for defined(INTR_MPSAFE) -- something which never was a #define. Correct the definitions.
This make INTR_TYPE_AV finally get used instead of the lower-priority INTR_TYPE_TTY, so it's quite possible some improvement will be had on sound driver performance. It would also make all the drivers marked INTR_MPSAFE actually run without Giant (which does seem to work for me), but: INTR_MPSAFE HAS BEEN REMOVED FROM EVERY SOUND DRIVER! It needs to be re-added on a case-by-case basis since there is no one who will vouch for which sound drivers, if any, willy actually operate correctly without Giant, since there hasn't been testing because of this bug disabling INTR_MPSAFE.

Mega busdma API commit.
Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg. Lockfunc allows a driver to provide a function for managing its locking semantics while using busdma. At the moment, this is used for the asynchronous busdma_swi and callback mechanism. Two lockfunc implementations are provided: busdma_lock_mutex() performs standard mutex operations on the mutex that is specified from lockfuncarg. dftl_lock() is a panic implementation and is defaulted to when NULL, NULL are passed to bus_dma_tag_create(). The only time that NULL, NULL should ever be used is when the driver ensures that bus_dmamap_load() will not be deferred. Drivers that do not provide their own locking can pass busdma_lock_mutex,&Giant args in order to preserve the former behaviour.
sparc64 and powerpc do not provide real busdma_swi functions, so this is largely a noop on those platforms. The busdma_swi on is64 is not properly locked yet, so warnings will be emitted on this platform when busdma callback deferrals happen.
If anyone gets panics or warnings from dflt_lock() being called, please let me know right away.

many changes:
* add new channels to the end of the list so channels used in order of addition
* de-globalise definition of struct snddev_info and provide accessor functions where necessary.
* move the $FreeBSD$ tag in each .c file into a macro and allow the /dev/sndstat handler to display these when set to maximum verbosity to aid debugging.
* allow each device to register its own sndstat handler to reduce the amount of groping sndstat must do in foreign structs.

use a global devclass for all drivers - i'm not entirely sure why this worked before.
mixer, dsp and sndstat are seperate devices - give them their own cdevsws instead of demuxing requests sent to a single cdevsw.
use the si_drv1/si_drv2 fields in dev_t structures for holding information specific to an open instance of mixer/dsp.
nuke /dev/{dsp,dspW,audio}[0-9]* links - this functionality is now provided using cloning.

mega-commit.
this introduces a new buffering mechanism which results in dramatic simplification of the channel manager.
as several structures have changed, we take the opportunity to move their definitions into the source files where they are used, make them private and de-typedef them.
the sound drivers are updated to use snd_setup_intr instead of bus_setup_intr, and to comply with the de-typedefed structures.
the ac97, mixer and channel layers have been updated with finegrained locking, as have some drivers- not all though. the rest will follow soon.

modify chn_setblocksize() to pick a default soft-blocksize appropriate to the sample rate and format in use. it will aim for a power of two size small enough to generate block sizes of at most 20ms. it will also set the hard-blocksize taking into account rate/format conversions in use.

Update for pnp adjustments regarding NPNP.
Also, optimize out a mess of #if's that were duplicating work already done by config(8). For example, if a file is marked as "dev/sound/pci/foo.c optional pcm pci" then it's only added if pcm *and* pci are present, so #if NPCM > 0 and #if NPCI > 0 are totally redundant. A bit more work is still needed.
