Changelog for version 2.4
-------------------------
Since 2.3b
- Fixed bug which made it impossible to make long recordings to disk.
Recording was not restarted after a buffer overflow situation.
- Limited mixer support for GUS.
- Numerous improvements to the GUS driver by Andrew Robinson. Including
some click removal etc.
Since 2.3
- Fixed some minor bugs in the SB16 driver.
Since 2.2b
- Full SB16 DSP support. 8/16 bit, mono/stereo
- The SCO and FreeBSD versions should be in sync now. There are some
problems with SB16 and GUS in the freebsd versions.
The DMA buffer allocation of the SCO version has been polished but
there could still be some problems. At least it hogs memory.
The DMA channel
configuration method used in the sco/System is a hack.
- Support for the MPU emulation of the SB16.
- Some big arrays are now allocated boot time. This makes the bss segment
smaller which makes it possible to use the full driver with
NetBSD. These arrays are not allocated if no suitable soundcard is available.
- Fixed a bug in the compute_and_set_volume in gus_wave.c
- Fixed the too fast mono playback problem of SB Pro and PAS16.
Since 2.2
- Stereo recording for SB Pro. Somehow it was missing and nobody
had noticed it earlier.
- Minor polishing.
- Interpreting of boot time arguments (sound=) for Linux.
- Breakup of sb_dsp.c. Parts of the code has been moved to
sb_mixer.c and sb_midi.c
Since 2.1
- Preliminary support for SB16.
- The SB16 mixer is supported in it's native mode.
- Digitized voice capability up to 44.1 kHz/8 bit/mono
(16 bit and stereo support coming in the next release).
- Fixed some bugs in the digitized voice driver for PAS16.
- Proper initialization of the SB emulation of latest PAS16 models.
- Significantly improved /dev/dsp and /dev/audio support.
- Now supports half duplex mode. It's now possible to record and
playback without closing and reopening the device.
- It's possible to use smaller buffers than earlier. There is a new
ioctl(fd, SNDCTL_DSP_SUBDIVIDE, &n) where n should be 1, 2 or 4.
This call instructs the driver to use smaller buffers. The default
buffer size (0.5 to 1.0 seconds) is divided by n. Should be called
immediately after opening the device.
Since 2.0
Just cosmetic changes.

Release notes for the Linux Sound Driver 1.99.9
-----------------------------------------------
Release notes for the Linux Sound Driver 2.4
--------------------------------------------
******** THIS IS A BETA TEST RELEASE ********
which means that there can be some untested things. In theory
there is a risk that this driver causes some trouble to your system.
You should not use this driver before backing up your disks.
NOTE! The sound driver is a part of the Linux kernel distribution also.
Check that your kernel doesn't have more recent version than this
when installing a separately distributed sound driver. The
version number of this driver is defined in the makefile.
This version contains a driver for the SB16 also.
The SB16 driver requires separate DMA channels for the 8 and 16 bit
modes. There should be a way to share the 8 bit DMA channels between
these modes but this feature is not supported yet.
The SB16 DSP support is by Joerg Schubert (jsb@sth.ruhr-uni-bochum.de).
The SB16 driver has also the Midi input capability even at the same
time with the /dev/dsp. Also the WaveBlaster daughter board is supported.
No support for the ASP chip yet (the ASP chip can be installed but it's
not used by the driver).
You will need the snd-util-2.4.tar.gz and snd-data-0.1.tar.Z
packages to use this driver. They should be in the same
ftp site or BBS from where you got this driver. For
example at nic.funet.fi:pub/OS/Linux/*.
Welcome to use the Gravis UltraSound driver for Linux. This
driver still supports the same cards than version 1.0c
(SoundBlaster, SB Pro, Pro Audio Spectrum 16 and AdLib).
In addition there is rather limited support for MPU-401
There is a new version of the tracker program available (tracker-3_19.lzh) but
I don't know where it is available. The tracker 3.10 has bugs and it don't work
without some fixes. Look at the README of the snd-util-2.3.
If you are looking for the installation instructions, please
look at linux/Readme.
This version supports the following soundcards:
GUS, SoundBlaster, SB Pro, SB16, Pro Audio Spectrum 16 and AdLib.
In addition there is rather limited support for MPU-401.
(and compatible) midi cards. Also the OPL-3 synthesizer
of the SB Pro and PAS16 cards is now supported in the 4 OP
modes.
Most of the features of the /dev/sequencer device file are
available just for GUS owners.
The SoundBlaster 16 and SB 16 ASP cards are not supported.
They could work in mono mode with speeds < 22 kHz.
The OPL-3 chicp of the SB 16 should work (without problems?).
Is there anybody willing to implement the SB 16 support
(have the SB 16 and the SDK for it)?
This is the first version of the driver which has almost
all of the features which I have planned to include into
version 2.0. Some features are still missing and some ones
doesn't work.
NOTE! There are separate driver for CD-ROMS supported by
some soundcards. The driver for CDU31A (Fusion 16) is
called cdu31a-0.6.diff.z. It will be contained in the
Linux version 0.99.12. The driver for the CD-ROM of SB Pro
is sbpcd0.4.tar.gz (these were the latest versions when I wrote
this). These files should be at least at sunsite.unc.edu.
As far as I know, there is no driver for the SCSI interface of PAS16
(yet).
Also the SCSI interface of the PAS16 should be supported by
Linux 0.99.13k and later.
There is also a driver for joystick. Look for file joystick-0.5.tar.gz
(sunsite).
Since this driver is a sound driver, it will not contain support
for SCSI/CD-ROM/Joystick -devices.
Compatibility with the earlier versions
---------------------------------------
This is just like the version 1.99.7/1.99.8. There is just some minor
enhancements. Most of them are portability fixes. If you are porting
this driver to any OS, please look at the 386bsd/os.h. There is some
new macros and some macros have more parameters. In addition this file
contains some usefull comments.
In this version the ultrasound.h no longer includes the sys/soundcard.h
You have to change the gmod.c of the snd-util-2.0 package and to add an
include for it.
**** There is some ISC and 386bsd stuff in this driver. Please stay away ****
This stuff is here just because I want to be in sync with the porters. These
ports don't work yet.
IMPORTANT!!!!!!!!!!!!!!!!!!!!!!
This version is not binary or source compatible with the version 1.0c.
The ioctl() interface has changed completely since version 1.0c. All
programs using this driver must be at least recompiled.
The snd-util-1.99.6 package contains some utilities for this version.
The snd-util-2.0 package contains some utilities for this version.
The version 1.0c and earlier used a 'nonportable' ioctl calling scheme
where the input argument was passed by value and the output value was
@ -78,59 +79,46 @@ After version 1.99.0 this must be done as the following:
If you have an application written for the version 1.0, you should search
for the strings SNDCTL_ and SOUND_ and to check the parameters.
The following ioctl calls have changed:
SNDCTL_SEQ_GETOUTCOUNT
SNDCTL_SEQ_GETINCOUNT
SNDCTL_SEQ_TESTMIDI
SNDCTL_DSP_SPEED
SNDCTL_DSP_STEREO
SNDCTL_DSP_GETBLKSIZE
SNDCTL_DSP_SAMPLESIZE
SOUND_PCM_WRITE_CHANNELS
SOUND_PCM_WRITE_FILTER
SOUND_PCM_READ_RATE
SOUND_PCM_READ_CHANNELS
SOUND_PCM_READ_BITS
SOUND_PCM_READ_FILTER
SOUND_PCM_WRITE_BITS
SOUND_PCM_WRITE_RATE
SOUND_MIXER_READ_* (several ones)
SOUND_MIXER_WRITE_* (several ones)
Since the this version will support more than one synthesizer devices
at the same time, the ioctl(SNDCTL_FM_LOAD_INSTR) is obsolete. In addition
there is some new fields which must be initialized. Look at the sbiset.c in
the snd-util-1.99.6 package for further info.
the snd-util-2.0 package for further info.
The GUS patch format has changed since the version 1.99.3. You have to
use latest versions of the programs in the sound/gustest directory. In
addition the version 0.4g of the Adagio package supports this format.
This version is almost 100% compatible with the alpha test version (1.99.9). The
difference is in the installation procedure.
New features
Using this driver with other operating systems than Linux
---------------------------------------------------------
This package contains just the Linux version. The version 2.3
for SCO is available at nic.funet.fi:pub/OS/Linux/ALPHA/sound.
The version 2.3 doesn't work well with xxxxxBSD. Use the version
2.3 for them.
/dev/sndstat
------------
There is also some changes which make this version more usable than
the version 1.0c.
- /dev/dsp and /dev/audio
The DMA buffering is now little bit more intelligent than earlier. The
buffer size is selected run-time so that a buffer holds data for 0.5 to
1.0 seconds of recording or playback. This makes recording more comfortable
than with version 1.0. With the previous version there was sometimes more
than 10 seconds of delay before the driver returned the first input byte.
There is also support for more than one digitized voice devices. The device
files /dev/dsp1 and /dev/audio1 (minor 19 and 20) are available with PAS16.
The /dev/dsp (/dev/audio) is connected to the PCM circuit of the PAS16 itself
and the /dev/dsp1 (/dev/audio1) to the SB emulation of PAS16 card. Two
dsp/audio devices are available also if you have combination of SB and GUS.
With GUS and PAS16 you will have even three dsp/audio devices. These devices
can be used independently and can be active at the same time (3 channels
at the same time propably don't work).
The dsp/audio support of PAS16 should be much cleaner now since the
constant clicking sound between the DMA blocks (about once per second) has
been eliminated.
The stereo playback of GUS doesn't work perfectly. There is lot of
clicking in the output.
- /dev/mixer
No changes.
There is no mixer for the GUS yet.
- /dev/sequencer
This part has the most changes. Mostly to support the rich
features of the Gravis UltraSound. There is also the support
for the OPL-3 synthesizer chip.
- /dev/sndstat
The /dev/sndstat is now available in the SCO and BSD versions also.
This is a new devicefile for debugging purposes. A better place for
it is in the /proc -directory but I was just too lazy to implement it

Known bugs
----------
- There was clicking during stereo playback to /dev/dsp with GUS.
* Fixed in 1.99.9 *
- High speed recording of long audio samples (>20 second) to disk
is not possible. Everything works until next sync() which delays the
recording process too much. A delay longer than 0.1 to 0.3 seconds is
too much.
- The SB16 driver sometimes swaps the left and right channels together.
- Midi input doesn't work with SB and SB Pro (SB16 works).
- It's not possible to open /dev/dsp (or /dev/audio) while the
/dev/sequencer is open for output and GUS is the only soundcard
installed. It's possible if /dev/dsp is opened before /dev/sequencer
@ -180,12 +173,70 @@ Known bugs
- MPU-401 driver hangs the computer on boot if there is no MPU-401 installed.
It uses by default the I/O port 0x330 whic is used by Adaptec 1542 SCSI
adapter.
- There are some problems in midi input with MPU-401 and the SB16 midi
(MPU-401 emulation). This makes it impossible to read long sysex dumps
using these devices.
- The /dev/sequencer playback to GUS sounds sometimes rather weird. Hitting
^C and playing again should solve this problem. This is propably caused by
incompatibilities between GUS and certain VLB motherboards. Try to avoid
incompatibilities between GUS and certain VLB motherboards (like mine).
Try to avoid
switching between VTs while patches are being loaded to the GUS.
- There was some problems with GUS and Mitsumi CD in version 1.99.8. Fixed
in 1.99.9.
- /dev/audio sounded like stereo with GUS. Fixed in 1.99.9.
This problem disappears completely if you define GUS_PATCH_NO_DMA in the
local.h (after make config in linux). The drawback is that patch loading
without DMA takes several times longer than with DMA.
- There is a skeleton of the patch manager support. It don't work in
this version.
Future development
------------------
- Since this driver is no longer just the Linux Sound Driver, it's time
to give it a new name. I have planned to use name VoxWare.
- I'm writing a Hacker's guide to the VoxWare sound driver. Should
be ready within this(/next) year (alpha version).
- Completion of the ISC, SCO and BSD ports. Port to SVR4.2.
- I'm interested to implement/include support for new soundcards and
operating systems.
Hint for the soundcard and OS manufacturers:
I'm collecting soundcards (high end ones) and SDKs for them. In
addition I'm collecting PC operating systems. I will be happy if
somebody sends me such items. In addition such kind of donation
makes it easier to change the VoxWare driver to support your
soundcard or operating system. However, please contact me before
sending anything.
I will propably release some fix versions within this and next year. At
least when the non-Linux versions get ready. The next major release (3.0)
will be quite complete rewrite and released after about a year (end of 94 or
beginning of 95).
