12006f3c05 Don't clobber the error returned by uiomove() when starting the audio 
output (in case we got a partial block).  Fixes PR #7722, from
Antti Kantee <pooka@iki.fi>.

9e14ee3c6e Fix two small bugs: 
(1) Fix sense of a strcmp() test so that the monitor subdevice of the
    mixer is properly identified.
(2) Use hw_if->set_port() instead of hw_if->get_port() when changinh
    the monitor level in audiosetinfo().

Fixes PR kern/7661.

6292c7eda0 Make midi_attach_mi() and audioprint() available also if MIDIBUS 
(but not necessarily MIDI) is defined.
Fixes PR port-i386/6615 (Krister Walfridsson <cato@ulysses.df.lth.se>).
(XXX this should probably go into a separate file to get rid of
the #ifdef mess)

db3051d720 fix problems in many d_mmap routines: 
- returned EOPNOTSUPP rather than -1.
	- no check for negative offset.
many of these fix potential security problems in these drivers.


XXX XXX XXX
the d_mmap cdev routine should be changed to have a prototype like:
	paddr_t (*d_mmap) __P((dev_t, off_t, int));

cd09067eb4 * Redo the way the way the MIDI driver attaches to audio devices. 
* Improve the midisyn layer a little.
* Add a driver for the Yamaha OPL[23] FM synths.
  The opl driver is not finished yet; it sounds pretty awful.

For some strange reason I cannot get any FM sound from my SB64 cards,
but a regular SB16 works fine.

48bae9ee88 Add MIDI support. The MIDI devices can be accessed as ``raw'' through 
the /dev/rmidiN devices, or with a sequencer interface via /dev/music.
So far the only supported MIDI device is the MPU401 port on SoundBlaster
(and only on SB on isapnp, since we do not have locators with multiple
values yet).

e7029fc0da Make the audio API (almost) SunOS compatible. 
The changes is to allow some limited mixer manipulation through
the audio device (instead of the mixer device).
This rendered 4 methods in audio_hw_if unused so garbage collect these.

6616d47838 - Change audio_hw_if a little: set_param now sets the play and record modes 
at the same time instead by using two different calls.  This enables
  it to check more easily if the combined mode is all right.
- Improve the error checking in audio.c.
- Add a new audio property, AUDIO_PROP_INDEPENDENT, show if the
  play and record settings are independent.
- Fix some buglets in audio.c.
