4 | Changelog for version 3.8o | |
5 | -------------------------- | |
6 | ||
7 | Since 3.8h | |
8 | - Included support for OPL3-SA1 and SoftOSS | |
9 | ||
10 | Since 3.8 | |
11 | - Fixed SNDCTL_DSP_GETOSPACE | |
12 | - Compatibility fixes for Linux 2.1.47 | |
13 | ||
14 | Since 3.8-beta21 | |
15 | - Fixed all known bugs (I think). | |
16 | ||
17 | Since 3.8-beta8 | |
18 | - Lot of fixes to audio playback code in dmabuf.c | |
19 | ||
20 | Since 3.8-beta6 | |
21 | - Fixed the famous Quake delay bug. | |
22 | ||
23 | Since 3.8-beta5 | |
24 | - Fixed many bugs in audio playback. | |
25 | ||
26 | Since 3.8-beta4 | |
27 | - Just minor changes. | |
28 | ||
29 | Since 3.8-beta1 | |
30 | - Major rewrite of audio playback handling. | |
31 | - Added AWE32 support by Takashi Iwai (in ./lowlevel/). | |
32 | ||
33 | Since 3.7-beta# | |
34 | - Passing of ioctl() parameters between soundcard.c and other modules has been | |
35 | changed so that arg always points to kernel space. | |
36 | - Some bugfixes. | |
37 | ||
38 | Since 3.7-beta5 | |
39 | - Disabled MIDI input with GUS PnP (Interwave). There seems to be constant | |
40 | stream of received 0x00 bytes when the MIDI receiver is enabled. | |
41 | ||
42 | Since 3.5 | |
43 | - Changes almost everywhere. | |
44 | - Support for OPTi 82C924-based sound cards. | |
45 | ||
46 | Since 3.5.4-beta8 | |
47 | - Fixed a bug in handling of non-fragment sized writes in 16 bit/stereo mode | |
48 | with GUS. | |
49 | - Limited minimum fragment size with some audio devices (GUS=512 and | |
50 | SB=32). These devices require more time to "recover" from processing | |
51 | of each fragment. | |
52 | ||
53 | Since 3.5.4-beta6/7 | |
54 | - There seems to be problems in the OPTi 82C930 so cards based on this | |
55 | chip don't necessarily work yet. There are problems in detecting the | |
56 | MIDI interface. Also mixer volumes may be seriously wrong on some systems. | |
57 | You can safely use this driver version with C930 if it looks to work. | |
58 | However please don't complain if you have problems with it. C930 support | |
59 | should be fixed in future releases. | |
60 | - Got initialization of GUS PnP to work. With this version GUS PnP should | |
61 | work in GUS compatible mode after initialization using isapnptools. | |
62 | - Fixed a bug in handling of full duplex cards in write only mode. This has | |
63 | been causing "audio device opening" errors with RealAudio player. | |
64 | ||
65 | Since 3.5.4.beta5 | |
66 | - Changes to OPTi 82C930 driver. | |
67 | - Major changes to the Soundscape driver. The driver requires now just one | |
68 | DMA channel. The extra audio/dsp device (the "Not functional" one) used | |
69 | for code download in the earlier versions has been eliminated. There is now | |
70 | just one /dev/dsp# device which is used both for code download and audio. | |
71 | ||
72 | Since 3.5.4.beta4 | |
73 | - Minor changes. | |
74 | ||
75 | Since 3.5.4-beta2 | |
76 | - Fixed silent playback with ESS 688/1688. | |
77 | - Got SB16 to work without the 16 bit DMA channel (only the 8 bit one | |
78 | is required for 8 and 16 bit modes). | |
79 | - Added the "lowlevel" subdirectory for additional low level drivers that | |
80 | are not part of USS core. See lowlevel/README for more info. | |
81 | - Included support for ACI mixer (by Markus Kuhn). ACI is a mixer used in | |
82 | miroPCM sound cards. See lowlevel/aci.readme for more info. | |
83 | - Support for Aztech Washington chipset (AZT2316 ASIC). | |
84 | ||
85 | Since 3.5.4-beta1 | |
86 | - Reduced clicking with AD1848. | |
87 | - Support for OPTi 82C930. Only half duplex at this time. 16 bit playback | |
88 | is sometimes just white noise (occurs randomly). | |
89 | ||
90 | Since 3.5.2 | |
91 | - Major changes to the SB/Jazz16/ESS driver (most parts rewritten). | |
92 | The most noticeable new feature is support for multiple SB cards at the same | |
93 | time. | |
94 | - Renamed sb16_midi.c to uart401.c. Also modified it to work also with | |
95 | other MPU401 UART compatible cards than SB16/ESS/Jazz. | |
96 | - Some changes which reduce clicking in audio playback. | |
97 | - Copying policy is now GPL. | |
98 | ||
99 | Since 3.5.1 | |
100 | - TB Maui initialization support | |
101 | Since 3.5 | |
102 | - Improved handling of playback underrun situations. | |
103 | ||
104 | Since 3.5-beta10 | |
105 | - Bug fixing | |
106 | ||
107 | Since 3.5-beta9 | |
108 | - Fixed for compatibility with Linux 1.3.70 and later. | |
109 | - Changed boot time passing of 16 bit DMA channel number to SB driver. | |
110 | ||
111 | Since 3.5-beta8 | |
112 | - Minor changes | |
113 | ||
114 | Since 3.5-beta7 | |
115 | - enhancements to configure program (by Jeff Tranter): | |
116 | - prompts are in same format as 1.3.x Linux kernel config program | |
117 | - on-line help for each question | |
118 | - fixed some compile warnings detected by gcc/g++ -Wall | |
119 | - minor grammatical changes to prompts | |
120 | ||
121 | Since 3.5-beta6 | |
122 | - Fixed bugs in mmap() support. | |
123 | - Minor changes to Maui driver. | |
124 | ||
125 | Since 3.5-beta5 | |
126 | - Fixed crash after recording with ESS688. It's generally a good | |
127 | idea to stop inbound DMA transfers before freeing the memory | |
128 | buffer. | |
129 | - Fixed handling of AD1845 codec (for example Shuttle Sound System). | |
130 | - Few other fixes. | |
131 | ||
132 | Since 3.5-beta4 | |
133 | - Fixed bug in handling of uninitialized instruments with GUS. | |
134 | ||
135 | Since 3.5-beta3 | |
136 | - Few changes which decrease popping at end/beginning of audio playback. | |
137 | ||
138 | Since 3.5-beta2 | |
139 | - Removed MAD16+CS4231 hack made in previous version since it didn't | |
140 | help. | |
141 | - Fixed the above bug in proper way and in proper place. Many thanks | |
142 | to James Hightower. | |
143 | ||
144 | Since 3.5-beta1 | |
145 | - Bug fixes. | |
146 | - Full duplex audio with MAD16+CS4231 may work now. The driver configures | |
147 | SB DMA of MAD16 so that it doesn't conflict with codec's DMA channels. | |
148 | The side effect is that all 8 bit DMA channels (0,1,3) are populated in | |
149 | duplex mode. | |
150 | ||
151 | Since 3.5-alpha9 | |
152 | - Bug fixes (mostly in Jazz16 and ESS1688/688 supports). | |
153 | - Temporarily disabled recording with ESS1688/688 since it causes crash. | |
154 | - Changed audio buffer partitioning algorithm so that it selects | |
155 | smaller fragment size than earlier. This improves real time capabilities | |
156 | of the driver and makes recording to disk to work better. Unfortunately | |
157 | this change breaks some programs which assume that fragments cannot be | |
158 | shorter than 4096 bytes. | |
159 | ||
160 | Since 3.5-alpha8 | |
161 | - Bug fixes | |
162 | ||
163 | Since 3.5-alpha7 | |
164 | - Linux kernel compatible configuration (_EXPERIMENTAL_). Enable | |
165 | using command "cd /linux/drivers/sound;make script" and then | |
166 | just run kernel's make config normally. | |
167 | - Minor fixes to the SB support. Hopefully the driver works with | |
168 | all SB models now. | |
169 | - Added support for ESS ES1688 "AudioDrive" based cards. | |
170 | ||
171 | Since 3.5-alpha6 | |
172 | - SB Pro and SB16 supports are no longer separately selectable options. | |
173 | Enabling SB enables them too. | |
174 | - Changed all #ifndef EXCLUDE_xx stuff to #ifdef CONFIG_xx. Modified | |
175 | configure to handle this. | |
176 | - Removed initialization messages from the | |
177 | modularized version. They can be enabled by using init_trace=1 in | |
178 | the insmod command line (insmod sound init_trace=1). | |
179 | - More AIX stuff. | |
180 | - Added support for synchronizing dsp/audio devices with /dev/sequencer. | |
181 | - mmap() support for dsp/audio devices. | |
182 | ||
183 | Since 3.5-alpha5 | |
184 | - AIX port. | |
185 | - Changed some xxx_PATCH macros in soundcard.h to work with | |
186 | big endian machines. | |
187 | ||
188 | Since 3.5-alpha4 | |
189 | - Removed the 'setfx' stuff from the version distributed with kernel | |
190 | sources. Running 'setfx' is required again. | |
191 | ||
192 | Since 3.5-alpha3 | |
193 | - Moved stuff from the 'setfx' program to the AudioTrix Pro driver. | |
194 | ||
195 | Since 3.5-alpha2 | |
196 | - Modifications to makefile and configure.c. Unnecessary sources | |
197 | are no longer compiled. Newly created local.h is also copied to | |
198 | /etc/soundconf. "make oldconfig" reads /etc/soundconf and produces | |
199 | new local.h which is compatible with current version of the driver. | |
200 | - Some fixes to the SB16 support. | |
201 | - Fixed random protection fault in gus_wave.c | |
202 | ||
203 | Since 3.5-alpha1 | |
204 | - Modified to work with Linux-1.3.33 and later | |
205 | - Some minor changes | |
206 | ||
207 | Since 3.0.2 | |
208 | - Support for CS4232 based PnP cards (AcerMagic S23 etc). | |
209 | - Full duplex support for some CS4231, CS4232 and AD1845 based cards | |
210 | (GUS MAX, AudioTrix Pro, AcerMagic S23 and many MAD16/Mozart cards | |
211 | having a codec mentioned above). | |
212 | - Almost fully rewritten loadable modules support. | |
213 | - Fixed some bugs. | |
214 | - Huge amount of testing (more testing is still required). | |
215 | - mmap() support (works with some cards). Requires much more testing. | |
216 | - Sample/patch/program loading for TB Maui/Tropez. No initialization | |
217 | since TB doesn't allow me to release that code. | |
218 | - Using CS4231 compatible codecs as timer for /dev/music. | |
219 | ||
220 | Since 3.0.1 | |
221 | - Added allocation of I/O ports, DMA channels and interrupts | |
222 | to the initialization code. This may break modules support since | |
223 | the driver may not free some resources on unload. Should be fixed soon. | |
224 | ||
225 | Since 3.0 | |
226 | - Some important bug fixes. | |
227 | - select() for /dev/dsp and /dev/audio (Linux only). | |
228 | (To use select() with read, you have to call read() to start | |
229 | the recording. Calling write() kills recording immediately so | |
230 | use select() carefully when you are writing a half duplex app. | |
231 | Full duplex mode is not implemented yet.) Select works also with | |
232 | /dev/sequencer and /dev/music. Maybe with /dev/midi## too. | |
233 | ||
234 | Since 3.0-beta2 | |
235 | - Minor fixes. | |
236 | - Added Readme.cards | |
237 | ||
238 | Since 3.0-beta1 | |
239 | - Minor fixes to the modules support. | |
240 | - Eliminated call to sb_free_irq() in ad1848.c | |
241 | - Rewritten MAD16&Mozart support (not tested with MAD16 Pro). | |
242 | - Fix to DMA initialization of PSS cards. | |
243 | - Some fixes to ad1848/cs42xx mixer support (GUS MAX, MSS, etc.) | |
244 | - Fixed some bugs in the PSS driver which caused I/O errors with | |
245 | the MSS mode (/dev/dsp). | |
246 | ||
247 | Since 3.0-950506 | |
248 | - Recording with GUS MAX fixed. It works when the driver is configured | |
249 | to use two DMA channels with GUS MAX (16 bit ones recommended). | |
250 | ||
251 | Since 3.0-94xxxx | |
252 | - Too many changes | |
253 | ||
254 | Since 3.0-940818 | |
255 | - Fixes for Linux 1.1.4x. | |
256 | - Disables Disney Sound System with SG NX Pro 16 (less noise). | |
257 | ||
258 | Since 2.90-2 | |
259 | - Fixes to soundcard.h | |
260 | - Non blocking mode to /dev/sequencer | |
261 | - Experimental detection code for Ensoniq Soundscape. | |
262 | ||
263 | Since 2.90 | |
264 | - Minor and major bug fixes | |
265 | ||
266 | Since pre-3.0-940712 | |
267 | - GUS MAX support | |
268 | - Partially working MSS/WSS support (could work with some cards). | |
269 | - Hardware u-Law and A-Law support with AD1848/CS4248 and CS4231 codecs | |
270 | (GUS MAX, GUS16, WSS etc). Hardware ADPCM is possible with GUS16 and | |
271 | GUS MAX, but it doesn't work yet. | |
272 | Since pre-3.0-940426 | |
273 | - AD1848/CS4248/CS4231 codec support (MSS, GUS MAX, Aztec, Orchid etc). | |
274 | This codec chip is used in various sound cards. This version is developed | |
275 | for the 16 bit daughtercard of GUS. It should work with other cards also | |
276 | if the following requirements are met: | |
277 | - The I/O, IRQ and DMA settings are jumper selectable or | |
278 | the card is initialized by booting DOS before booting Linux (etc.). | |
279 | - You add the IO, IRQ and DMA settings manually to the local.h. | |
280 | (Just define GUS16_BASE, GUS16_IRQ and GUS16_DMA). Note that | |
281 | the base address bust be the base address of the codec chip not the | |
282 | card itself. For the GUS16 these are the same but most MSS compatible | |
283 | cards have the codec located at card_base+4. | |
284 | - Some minor changes | |
285 | ||
286 | Since 2.5 (******* MAJOR REWRITE ***********) | |
287 | ||
288 | This version is based on v2.3. I have tried to maintain two versions | |
289 | together so that this one should have the same features than v2.5. | |
290 | Something may still be missing. If you notice such things, please let me | |
291 | know. | |
292 | ||
293 | The Readme.v30 contains more details. | |
294 | ||
295 | - /dev/midi## devices. | |
296 | - /dev/sequencer2 | |
297 | ||
298 | Since 2.5-beta2 | |
299 | - Some fine tuning to the GUS v3.7 mixer code. | |
300 | - Fixed speed limits for the plain SB (1.0 to 2.0). | |
301 | ||
302 | Since 2.5-beta | |
303 | - Fixed OPL-3 detection with SB. Caused problems with PAS16. | |
304 | - GUS v3.7 mixer support. | |
305 | ||
306 | Since 2.4 | |
307 | - Mixer support for Sound Galaxy NX Pro (define __SGNXPRO__ on your local.h). | |
308 | - Fixed truncated sound on /dev/dsp when the device is closed. | |
309 | - Linear volume mode for GUS | |
310 | - Pitch bends larger than +/- 2 octaves. | |
311 | - MIDI recording for SB and SB Pro. (Untested). | |
312 | - Some other fixes. | |
313 | - SB16 MIDI and DSP drivers only initialized if SB16 actually installed. | |
314 | - Implemented better detection for OPL-3. This should be useful if you | |
315 | have an old SB Pro (the non-OPL-3 one) or a SB 2.0 clone which has a OPL-3. | |
316 | - SVR4.2 support by Ian Hartas. Initial ALPHA TEST version (untested). | |
317 | ||
318 | Since 2.3b | |
319 | - Fixed bug which made it impossible to make long recordings to disk. | |
320 | Recording was not restarted after a buffer overflow situation. | |
321 | - Limited mixer support for GUS. | |
322 | - Numerous improvements to the GUS driver by Andrew Robinson. Including | |
323 | some click removal etc. | |
324 | ||
325 | Since 2.3 | |
326 | - Fixed some minor bugs in the SB16 driver. | |
327 | ||
328 | Since 2.2b | |
329 | - Full SB16 DSP support. 8/16 bit, mono/stereo | |
330 | - The SCO and FreeBSD versions should be in sync now. There are some | |
331 | problems with SB16 and GUS in the FreeBSD versions. | |
332 | The DMA buffer allocation of the SCO version has been polished but | |
333 | there could still be some problems. At least it hogs memory. | |
334 | The DMA channel | |
335 | configuration method used in the SCO/System is a hack. | |
336 | - Support for the MPU emulation of the SB16. | |
337 | - Some big arrays are now allocated boot time. This makes the BSS segment | |
338 | smaller which makes it possible to use the full driver with | |
339 | NetBSD. These arrays are not allocated if no suitable sound card is available. | |
340 | - Fixed a bug in the compute_and_set_volume in gus_wave.c | |
341 | - Fixed the too fast mono playback problem of SB Pro and PAS16. | |
342 | ||
343 | Since 2.2 | |
344 | - Stereo recording for SB Pro. Somehow it was missing and nobody | |
345 | had noticed it earlier. | |
346 | - Minor polishing. | |
347 | - Interpreting of boot time arguments (sound=) for Linux. | |
348 | - Breakup of sb_dsp.c. Parts of the code has been moved to | |
349 | sb_mixer.c and sb_midi.c | |
350 | ||
351 | Since 2.1 | |
352 | - Preliminary support for SB16. | |
353 | - The SB16 mixer is supported in its native mode. | |
354 | - Digitized voice capability up to 44.1 kHz/8 bit/mono | |
355 | (16 bit and stereo support coming in the next release). | |
356 | - Fixed some bugs in the digitized voice driver for PAS16. | |
357 | - Proper initialization of the SB emulation of latest PAS16 models. | |
358 | ||
359 | - Significantly improved /dev/dsp and /dev/audio support. | |
360 | - Now supports half duplex mode. It's now possible to record and | |
361 | playback without closing and reopening the device. | |
362 | - It's possible to use smaller buffers than earlier. There is a new | |
363 | ioctl(fd, SNDCTL_DSP_SUBDIVIDE, &n) where n should be 1, 2 or 4. | |
364 | This call instructs the driver to use smaller buffers. The default | |
365 | buffer size (0.5 to 1.0 seconds) is divided by n. Should be called | |
366 | immediately after opening the device. | |
367 | ||
368 | Since 2.0 | |
369 | Just cosmetic changes. |
