There seems to be constant +stream of received 0x00 bytes when the MIDI receiver is enabled. + +Since 3.5 +- Changes almost everywhere. +- Support for OPTi 82C924-based sound cards. + +Since 3.5.4-beta8 +- Fixed a bug in handling of non-fragment sized writes in 16 bit/stereo mode + with GUS. +- Limited minimum fragment size with some audio devices (GUS=512 and + SB=32). These devices require more time to "recover" from processing + of each fragment. + +Since 3.5.4-beta6/7 +- There seems to be problems in the OPTi 82C930 so cards based on this + chip don't necessarily work yet. There are problems in detecting the + MIDI interface. Also mixer volumes may be seriously wrong on some systems. + You can safely use this driver version with C930 if it looks to work. + However please don't complain if you have problems with it. C930 support + should be fixed in future releases. +- Got initialization of GUS PnP to work. With this version GUS PnP should + work in GUS compatible mode after initialization using isapnptools. +- Fixed a bug in handling of full duplex cards in write only mode. This has + been causing "audio device opening" errors with RealAudio player. + +Since 3.5.4.beta5 +- Changes to OPTi 82C930 driver. +- Major changes to the Soundscape driver. The driver requires now just one + DMA channel. The extra audio/dsp device (the "Not functional" one) used + for code download in the earlier versions has been eliminated. There is now + just one /dev/dsp# device which is used both for code download and audio. + +Since 3.5.4.beta4 +- Minor changes. + +Since 3.5.4-beta2 +- Fixed silent playback with ESS 688/1688. +- Got SB16 to work without the 16 bit DMA channel (only the 8 bit one + is required for 8 and 16 bit modes). +- Added the "lowlevel" subdirectory for additional low level drivers that + are not part of USS core. See lowlevel/README for more info. +- Included support for ACI mixer (by Markus Kuhn). ACI is a mixer used in + miroPCM sound cards. See lowlevel/aci.readme for more info. +- Support for Aztech Washington chipset (AZT2316 ASIC). + +Since 3.5.4-beta1 +- Reduced clicking with AD1848. +- Support for OPTi 82C930. Only half duplex at this time. 16 bit playback + is sometimes just white noise (occurs randomly). + +Since 3.5.2 +- Major changes to the SB/Jazz16/ESS driver (most parts rewritten). + The most noticeable new feature is support for multiple SB cards at the same + time. +- Renamed sb16_midi.c to uart401.c. Also modified it to work also with + other MPU401 UART compatible cards than SB16/ESS/Jazz. +- Some changes which reduce clicking in audio playback. +- Copying policy is now GPL. + +Since 3.5.1 +- TB Maui initialization support +Since 3.5 +- Improved handling of playback underrun situations. + +Since 3.5-beta10 +- Bug fixing + +Since 3.5-beta9 +- Fixed for compatibility with Linux 1.3.70 and later. +- Changed boot time passing of 16 bit DMA channel number to SB driver. + +Since 3.5-beta8 +- Minor changes + +Since 3.5-beta7 +- enhancements to configure program (by Jeff Tranter): + - prompts are in same format as 1.3.x Linux kernel config program + - on-line help for each question + - fixed some compile warnings detected by gcc/g++ -Wall + - minor grammatical changes to prompts + +Since 3.5-beta6 +- Fixed bugs in mmap() support. +- Minor changes to Maui driver. + +Since 3.5-beta5 +- Fixed crash after recording with ESS688. It's generally a good + idea to stop inbound DMA transfers before freeing the memory + buffer. +- Fixed handling of AD1845 codec (for example Shuttle Sound System). +- Few other fixes. + +Since 3.5-beta4 +- Fixed bug in handling of uninitialized instruments with GUS. + +Since 3.5-beta3 +- Few changes which decrease popping at end/beginning of audio playback. + +Since 3.5-beta2 +- Removed MAD16+CS4231 hack made in previous version since it didn't + help. +- Fixed the above bug in proper way and in proper place. Many thanks + to James Hightower. + +Since 3.5-beta1 +- Bug fixes. +- Full duplex audio with MAD16+CS4231 may work now. The driver configures + SB DMA of MAD16 so that it doesn't conflict with codec's DMA channels. + The side effect is that all 8 bit DMA channels (0,1,3) are populated in + duplex mode. + +Since 3.5-alpha9 +- Bug fixes (mostly in Jazz16 and ESS1688/688 supports). +- Temporarily disabled recording with ESS1688/688 since it causes crash. +- Changed audio buffer partitioning algorithm so that it selects + smaller fragment size than earlier. This improves real time capabilities + of the driver and makes recording to disk to work better. Unfortunately + this change breaks some programs which assume that fragments cannot be + shorter than 4096 bytes. + +Since 3.5-alpha8 +- Bug fixes + +Since 3.5-alpha7 +- Linux kernel compatible configuration (_EXPERIMENTAL_). Enable + using command "cd /linux/drivers/sound;make script" and then + just run kernel's make config normally. +- Minor fixes to the SB support. Hopefully the driver works with + all SB models now. +- Added support for ESS ES1688 "AudioDrive" based cards. + +Since 3.5-alpha6 +- SB Pro and SB16 supports are no longer separately selectable options. + Enabling SB enables them too. +- Changed all #ifndef EXCLUDE_xx stuff to #ifdef CONFIG_xx. Modified +configure to handle this. +- Removed initialization messages from the +modularized version. They can be enabled by using init_trace=1 in +the insmod command line (insmod sound init_trace=1). +- More AIX stuff. +- Added support for synchronizing dsp/audio devices with /dev/sequencer. +- mmap() support for dsp/audio devices. + +Since 3.5-alpha5 +- AIX port. +- Changed some xxx_PATCH macros in soundcard.h to work with + big endian machines. + +Since 3.5-alpha4 +- Removed the 'setfx' stuff from the version distributed with kernel + sources. Running 'setfx' is required again. + +Since 3.5-alpha3 +- Moved stuff from the 'setfx' program to the AudioTrix Pro driver. + +Since 3.5-alpha2 +- Modifications to makefile and configure.c. Unnecessary sources + are no longer compiled. Newly created local.h is also copied to + /etc/soundconf. "make oldconfig" reads /etc/soundconf and produces + new local.h which is compatible with current version of the driver. +- Some fixes to the SB16 support. +- Fixed random protection fault in gus_wave.c + +Since 3.5-alpha1 +- Modified to work with Linux-1.3.33 and later +- Some minor changes + +Since 3.0.2 +- Support for CS4232 based PnP cards (AcerMagic S23 etc). +- Full duplex support for some CS4231, CS4232 and AD1845 based cards +(GUS MAX, AudioTrix Pro, AcerMagic S23 and many MAD16/Mozart cards +having a codec mentioned above). +- Almost fully rewritten loadable modules support. +- Fixed some bugs. +- Huge amount of testing (more testing is still required). +- mmap() support (works with some cards). Requires much more testing. +- Sample/patch/program loading for TB Maui/Tropez. No initialization +since TB doesn't allow me to release that code. +- Using CS4231 compatible codecs as timer for /dev/music. + +Since 3.0.1 +- Added allocation of I/O ports, DMA channels and interrupts +to the initialization code. This may break modules support since +the driver may not free some resources on unload. Should be fixed soon. + +Since 3.0 +- Some important bug fixes. +- select() for /dev/dsp and /dev/audio (Linux only). +(To use select() with read, you have to call read() to start +the recording. Calling write() kills recording immediately so +use select() carefully when you are writing a half duplex app. +Full duplex mode is not implemented yet.) Select works also with +/dev/sequencer and /dev/music. Maybe with /dev/midi## too. + +Since 3.0-beta2 +- Minor fixes. +- Added Readme.cards + +Since 3.0-beta1 +- Minor fixes to the modules support. +- Eliminated call to sb_free_irq() in ad1848.c +- Rewritten MAD16&Mozart support (not tested with MAD16 Pro). +- Fix to DMA initialization of PSS cards. +- Some fixes to ad1848/cs42xx mixer support (GUS MAX, MSS, etc.) +- Fixed some bugs in the PSS driver which caused I/O errors with + the MSS mode (/dev/dsp). + +Since 3.0-950506 +- Recording with GUS MAX fixed. It works when the driver is configured + to use two DMA channels with GUS MAX (16 bit ones recommended). + +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 sound cards. 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 sound card 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 its 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. |
