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. |
