07076ce1f7 Bump the buffersize from 0x1000 to 0x4000. 
0x1000 gets underflows on my dell 7500 whenever I moved the mouse.
(reported as "hwptr went backwards...", with jumpy sound)
Sounds great now....

612276f48c do not blindly assume 8khz is supported on open(). try for 8khz but respect 
minspeed/maxspeed specified by the hw driver.

ab3978871b adjust dma channels for vibra16x; recording should now work. full duplex does 
not work on vibra16x, so is disabled.

eadd0f839e split up sb16 and sb/sbpro drivers 
we do not support sb versions <2.00, and the sb8 driver has not been tested
yet.

these drivers are not yet enabled by default.

46aa3347cb Convert all users of fldoff() to offsetof(). fldoff() is bad 
because it only takes a struct tag which makes it impossible to
use unions, typedefs etc.

Define __offsetof() in <machine/ansi.h>

Define offsetof() in terms of __offsetof() in <stddef.h> and <sys/types.h>

Remove myriad of local offsetof() definitions.

Remove includes of <stddef.h> in kernel code.

NB: Kernelcode should *never* include from /usr/include !

Make <sys/queue.h> include <machine/ansi.h> to avoid polluting the API.

Deprecate <struct.h> with a warning.  The warning turns into an error on
01-12-2000 and the file gets removed entirely on 01-01-2001.

db90128160 Avoid the modules madness I inadvertently introduced by making the 
cloning infrastructure standard in kern_conf.  Modules are now
the same with or without devfs support.

If you need to detect if devfs is present, in modules or elsewhere,
check the integer variable "devfs_present".

This happily removes an ugly hack from kern/vfs_conf.c.

This forces a rename of the eventhandler and the standard clone
helper function.

Include <sys/eventhandler.h> in <sys/conf.h>: it's a helper #include
like <sys/queue.h>

Remove all #includes of opt_devfs.h they no longer matter.

15/16 of the buffer is skipped or we go backwards by < 1/16 of buffer size.

which sound unit the /dev/{dsp,mixer,dspW,audio} links point at.  this can

modify driver capability reporting format to list every audio format

that mono was unsupported.
