for both structs, the new members are 'bps' and 'msb', which
describe the number of bytes per sample and data alignment in the
sample, respectively. drivers must properly set these fields in
the 'query_encoding', 'set_parameters' and 'get_default_params'
hardware interface methods.

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

instead of 8-bit mono mulaw @ 8kHz.
this is just the infrastructure; no drivers are specifying a default
yet.

record modes. This makes possible to have blocks of the same duration if the
play and record formats are different. The API change is backward
compatible, so it shouldn't be noticed by current audio ports.

for audio(4) to try to keep up.

data structure these ioctls use, audio_bufinfo.
these ioctls return information about the play and record buffers
into the audio_bufinfo structure.
these are being added to aid in porting non-native audio applications
and libraries, and to fix issues in our OSS audio emulation. these
ioctls exist only on OpenBSD and should not be used in code intended
for distribution.

- update documentation to match this behaviour.

ioctl(fd, AUDIO_INITINFO, &info);
to initialize the audioinfo struct. This does not work as there
is no AUDIO_INITINFO ioctl command. Rather, the structure should be
initialized with something that looks like this:
AUDIO_INITINFO(&info);

- update to reality
- grammar, punctuation, rewording
- since this page describes both the mixer and audio devices,
add mention of the mixer device in relevant places
- use standard conventions for documenting ioctls
- macro and other mdoc fixes
- add some unmentioned audio devices and other cross-refs to
"see also"
help and ok jmc

- quote .Cd's
- add/remove .Pp's as necessary
- fix some .Re/.Rs's
- simplify macros

Tatoku Ogaito, banged into shape for OpenBSD by me. Recording has not been
tested yet, but mpg123 works fine. Sound still works after suspend/resume.
XXX: On the IBM ThinkPad X20, must disable pcibios else the cs4281 won't
generate interrupts. Cause yet unknown but probably not the driver's fault.
YMMV on other laptops with this chip.
