is 946db35c9b Modifications to aucc.c for more input formats and 14bit stereo output.
By Bernardo Innocenti, submitted as PR 6787.
Some KNF-ifying done by myself, so you might want to blame me instead
if the original patch worked for you.

augustss 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.

is a90ace971a Workaround for the "xanim volume setting problem":
We play mono samples on all 4 channels.
However, we get the volume settings for mono samples as a symmetic two-channel
setting... the other two channels used to stay at max volume...
I believe that something else is wrong here, but dont want to change MI
code (which in turn influences a couple of MD driver) thus late in the release
cycle.

augustss 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.

augustss 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.

augustss 332ad95e76 Change the MI audio driver so it attaches to the MD driver in the
normal way.  This requires adding a line to the config files to
get audio to work again.

augustss 658656bb99 Audio changes:
- Change the way attach and open works to allow multiple audio
	  devices.
	- Split the mulaw.c file into two to avoid dragging in mulaw
	  convertsion when they are not needed.  Add 16 bit alaw/mulaw tables.
	- Change the way audio properties are gotten.
	- Recognize more versions os SoundBlaster.

augustss a63034762b Audio: Remove the machine dependant code I put in audio.c by mistake.
This adds another method to audio_hw_if.  Also remove a field from
audio_hw_if that was not read-only.

augustss d828d675e3 Update forgotten audio driver for changes in audio_hw_if. 1997-07-28 10:04:35 +00:00

augustss 5b3b56dd1a Garbage collect some unused routines. 1997-07-15 07:51:04 +00:00
augustss 8727da130b In the name of backwards compatibility AUDIO_ENCODING_LINEAR has been
renamed AUDIO_ENCODING_SLINEAR and AUDIO_ENCODING_LINEAR reverts to the
NetBSD 1.2 sematics.  A kernel with COMPAT_12 defined will accept
AUDIO_ENCODING_LINEAR and treat it as before, without COMPAT_12 it
will be rejected.
1997-07-15 07:46:04 +00:00
is c7e3ab1310 - Fix gain control.
- play mono stuff on all channels.
1997-07-10 22:18:42 +00:00
is e76096387d Make multichannel output work. The cc parameter to hw_start_output is
a byte counter, it seems. Somebody should really write man 9 audio_if.
While here, make debug output invisible #ifndef AUCCDEBUG.
1997-07-09 22:37:08 +00:00
is 5171612d6c Multichannel output still doesn't work, but while working on it, I repaired
the double buffering code, and setting a couple of other parameters works now.
1997-07-04 21:00:15 +00:00
is 7fe3065765 Make aucc work in the presence of LEV6_DEFER. 1997-06-23 23:46:23 +00:00
kleink df92c57dc5 Change last commit to use `#error'. 1997-06-21 22:46:43 +00:00
is ff79d0a7dd Make this fail to compile with LEV6_DEFER.
XXX This isn't nice, but stopping the  system clock isn't nice, either.
We will repair this soon.
1997-06-21 21:52:37 +00:00
is 4b718644a7 Add RCS ids, and clean up some unused in newstyle audio hardware drivers
functions.
1997-06-20 21:45:11 +00:00
is 4a4420172f Actually commit the sample rate to the hardware.
While we're here, add missing parts of (software encoded) ULINEAR encoding.

is c577eb43ec A bit more of KNF. 1997-06-15 21:11:33 +00:00
is b14e608272 Amiga custom chip audio hardware driver, by Stefan Thesing
(thesing@cs.uni-sb.de), heavily hacked upon by me to
- make it work with -current audio system
- make it shut off Amiga audio DMA only at appropriate places.
XXX A couple of bugs still remain, which well be handled later.
XXX Among them: only mono output; doesn't refuse to handle input, but chokes;
will not play last millichunk (is this 20 ms?) of data.
