Changelog for version 2.5
|
|
-------------------------
|
|
|
|
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 usefull 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.
