Amancio. There is some SoundSource support here that is primitive and probably doesn't work, but I'll let the two submitters let me know how my integration of that was since I don't have this card to test. I've only tested this on my GUS MAX since it's all I have. This all probably needs to be re-done anyway since we're widely variant from the original VOXWARE source in the current layout.

Changelog for version 3.0-950506
|
|
------------------------------------
|
|
|
|
Since 3.0-94xxxx
|
|
- Too many changes
|
|
|
|
Since 3.0-940818
|
|
- Fixes for Linux 1.1.4x.
|
|
- Disables Disney Sound System with SG NX Pro 16 (less noise).
|
|
|
|
Since 2.90-2
|
|
- Fixes to soundcard.h
|
|
- Non blocking mode to /dev/sequencer
|
|
- Experimental detection code for Ensoniq Soundscape.
|
|
|
|
Since 2.90
|
|
- Minor and major bug fixes
|
|
|
|
Since pre-3.0-940712
|
|
- GUS MAX support
|
|
- Partially working MSS/WSS support (could work with some cards).
|
|
- Hardware u-Law and A-Law support with AD1848/CS4248 and CS4231 codecs
|
|
(GUS MAX, GUS16, WSS etc). Hardware ADPCM is possible with GUS16 and
|
|
GUS MAX, but it doesn't work yet.
|
|
Since pre-3.0-940426
|
|
- AD1848/CS4248/CS4231 codec support (MSS, GUS MAX, Aztec, Orchid etc).
|
|
This codec chip is used in various soundcards. This version is developed
|
|
for the 16 bit daughtercard of GUS. It should work with other cards also
|
|
if the following requirements are met:
|
|
- The I/O, IRQ and DMA settings are jumper selectable or
|
|
the card is initialized by booting DOS before booting Linux (etc.).
|
|
- You add the IO, IRQ and DMA settings manually to the local.h.
|
|
(Just define GUS16_BASE, GUS16_IRQ and GUS16_DMA). Note that
|
|
the base address bust be the base address of the codec chip not the
|
|
card itself. For the GUS16 these are the same but most MSS compatible
|
|
cards have the codec located at card_base+4.
|
|
- Some minor changes
|
|
|
|
Since 2.5 (******* MAJOR REWRITE ***********)
|
|
|
|
This version is based on v2.3. I have tried to maintain two versions
|
|
together so that this one should have the same features than v2.5.
|
|
Something may still be missing. If you notice such things, please let me
|
|
know.
|
|
|
|
The Readme.v30 contains more details.
|
|
|
|
- /dev/midi## devices.
|
|
- /dev/sequencer2
|
|
|
|
Since 2.5-beta2
|
|
- Some fine tuning to the GUS v3.7 mixer code.
|
|
- Fixed speed limits for the plain SB (1.0 to 2.0).
|
|
|
|
Since 2.5-beta
|
|
- Fixed OPL-3 detection with SB. Caused problems with PAS16.
|
|
- GUS v3.7 mixer support.
|
|
|
|
Since 2.4
|
|
- Mixer support for Sound Galaxy NX Pro (define __SGNXPRO__ on your local.h).
|
|
- Fixed truncated sound on /dev/dsp when the device is closed.
|
|
- Linear volume mode for GUS
|
|
- Pitch bends larger than +/- 2 octaves.
|
|
- MIDI recording for SB and SB Pro. (Untested).
|
|
- Some other fixes.
|
|
- SB16 MIDI and DSP drivers only initialized if SB16 actually installed.
|
|
- Implemented better detection for OPL-3. This should be useful if you
|
|
have an old SB Pro (the non-OPL-3 one) or a SB 2.0 clone which has a OPL-3.
|
|
- SVR4.2 support by Ian Hartas. Initial ALPHA TEST version (untested).
|
|
|
|
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.
