История звуковых карт Creative Technology: от C/MS до Sound Blaster 1.0

Family of sound cards by Creative Technology

The history of Creative sound cards started with the release of the Creative Music System ("C/MS") CT 1300 board in August 1987. It contained two Philips SAA1099 integrated circuits, which, together, provided 12 channels of square wave "bee in a box" stereo sound, four channels of which can be used for noise. These ICs were featured earlier in various popular electronics magazines around the world. For many years Creative tended to use off the shelf components and manufacturers' reference designs for their early products. The various integrated circuits had white or black paper stickers fully covering their top thus hiding their identity. On the C/MS board in particular, the Philips chips had white pieces of paper with a fantasy CMS 301 inscription on them: real Creative parts usually had consistent CT number references. Surprisingly, the board also contained a large 40 pin DIP integrated circuit, bearing a CT 1302A CTPL 8708 (Creative Technology Programmable Logic) serigraphed inscription and looking exactly like the DSP of the later Sound Blaster. This chip allows software to automatically detect the card by certain register reads and writes. Including the use of Creative Technology.

A year later, in 1988, Creative marketed the C/MS via Radio Shack under the name Game Blaster. This card was identical in every way to the precursor C/MS hardware. Whereas the C/MS package came with five floppy disks full of utilities and song files, Creative supplied only a single floppy with the basic utilities and game patches to allow Sierra Online's games using the Sierra Creative Interpreter engine to play music with the card and it also included a later revision of the game Silpheed that added C/MS support.

In 2017 hobbyists developed a clone CT1300 PCB.

The Sound Blaster 1.0 (code named "Killer Kard"), CT1320A, was released in 1989. In addition to Game Blaster features, it has a 9 voice (11 voices in drum mode) FM synthesizer using the Yamaha YM3812 chip, also known as OPL2. It provided compatibility with the market leader AdLib sound card, which had gained support in PC games in the preceding year. Creative used the "DSP" acronym to designate the digital audio part of the Sound Blaster. This stood for Digital Sound Processor, rather than the more common digital signal processor, and is a simple microcontroller from the Intel MCS 51 family (supplied by Intel and Matra MHS, among others). It can play back 8 bit monaural sampled sound at up to 23 kHz sampling frequency and record 8 bit at up to 12 kHz. The sole DSP like features of the circuit are ADPCM decompression and a primitive non MPU 401 compatible MIDI interface. The ADPCM decompression schemes supported are 2 to 1, 3 to 1 and 4 to 1. The CT1320B variety of the Sound Blaster 1.0 typically has C/MS chips installed in sockets rather than soldered on the PCB, though units do exist with the C/MS chips soldered on. Some sources note that the original Sound Blaster 1.0 was produced under the CT1310 number. This however is a topic of ongoing debate. Creative refers to CT1310 for the Sound Blaster 1.0 on its website. In less than a year, the Sound Blaster became the top selling expansion card for the PC. It achieved this by providing an AdLib compatible product, with additional features, for the same, and often lower, price. The inclusion of a game port was important to its early success. PCs of this era did not include a game port. Game port cards were costly (around US$50) and used one of the few expansion slots PCs had at the time. Given the choice between an AdLib card or a fully compatible Sound Blaster card that came with a game port, saved a slot, and included the "DSP" for not much more in price, many consumers opted for the Sound Blaster. In game support for the digital portion of the card did not happen until after the Sound Blaster had gained dominance. When Microsoft announced Multimedia PC (MPC) in November 1990, it suggested to developers that they use the Sound Blaster as it was the only sound card that came close to complying with the MPC standard. The press speculated that Microsoft based the MPC standard on the Sound Blaster's specifications. By 1993 Computer Gaming World wondered "why would a gamer" buy a competing AdLib card that was not Sound Blaster compatible. Creative advertised the Sound Blaster 16 ("the 16 bit sound standard") with the slogan "Get Real", emphasizing its "real 100% Sound Blaster compatibility" and rhetorically asking "why those other manufacturers spend so much time comparing themselves to Sound Blaster".

Compute! in 1989 stated that with Sound Blaster, "IBM compatible computers have taken the lead in sound and music for personal computers". Naming it a Compute! Choice, the magazine described the quality of the opening music of Space Quest III with the card as "extraordinary", praising the quality compared to the Roland MT 32 and Ad Lib versions. Compute! approved of the card's DMA and Creative's dissemination of technical information, and concluded that while the more expensive MT 32 was superior, Sound Blaster's audio quality was better than that of Ad Lib or Game Blaster.

Released in 1990, the Sound Blaster 1.5, CT1320C, dropped the C/MS chips, which were no longer popular with game developers. Instead, the board had two empty sockets, which could be user upgraded by purchasing the C/MS chips directly from Creative or Phillips SAA 1099s from another source. Otherwise the card functions identically to the Sound Blaster 1.0. The CT1320U variety has the same layout as the CT1320C.

The final revision of the original Sound Blaster, the Sound Blaster 2.0 was released in October 1991, CT1350, added support for "auto init" DMA, which assisted in producing a continuous loop of double buffered sound output. Similar to version 1.0 and 1.5, it used a 1 channel 8 bit DAC. However, the maximum sampling rate was increased to 44 kHz for playback, and 15 kHz for record. The DSP's MIDI UART was upgraded to full duplex and offered time stamping features, but was not yet compatible with the MPU 401 interface used by professional MIDI equipment. The Sound Blaster 2.0's PCB layout used more highly integrated components, both shrinking the board's size and reducing manufacturing cost. Owners of previous revision Sound Blaster boards could upgrade their board by purchasing the V2.00 DSP chip from Creative Labs, and swapping the older DSP V1.0x with the newer replacement. The upgraded board gained the auto init DMA and new MIDI capabilities of the Sound Blaster 2.0 but not the expanded sampling rates. The upgrade was necessary for full compatibility with the Windows 3.0 Multimedia Extensions upgrade.

Sound Blaster MCV, CT5320, was a version created for IBM PS/2 model 50 and higher and their ISA incompatible Micro Channel architecture. The MCV Sound Blaster has some issues outputting audio while running on PS/2s with CPUs running faster than 16 MHz. However, the joystick interface is still inoperable on PS/2s it was designed for due to the slow speed Schottky chips that have been installed. None of these timing issues affect the Yamaha YM3812. Some of the MCV Sound Blasters were released with faster Schottkys which eradicated some of the problems.

Model CT1330, announced in May 1991, was the first significant redesign of the card's core features, and complied with the Microsoft MPC standard The Sound Blaster Pro supported faster digital input and output sampling rates (up to 22.05 kHz stereo or 44.1 kHz mono), added a "mixer" to provide a crude master volume control (independent of the volume of sound sources feeding the mixer), and a crude high pass or low pass filter. The Sound Blaster Pro used a pair of YM3812 chips to provide stereo music synthesis (one for each channel). The Sound Blaster Pro was fully backward compatible with the original Sound Blaster line, and by extension, the AdLib sound card. The Sound Blaster Pro was the first Creative sound card to have a built in CD ROM interface. Most Sound Blaster Pro cards featured a proprietary interface for a Panasonic (Matsushita MKE) drive. The Sound Blaster Pro cards are basically 8 bit ISA cards, they use only the lower 8 data bits of the ISA bus. While at first glance it appears to be a 16 bit ISA card, it does not have 'fingers' for data transfer on the higher "AT" portion of the bus connector. It uses the 16 bit extension to the ISA bus to provide the user with an additional choice for an IRQ (10) and DMA (0)m channel only found on the 16 bit portion of the edge connector. A short lived joint developed project between Creative and Tandy resulted in the Creative/Tandy Multimedia Sound Adapter, 849–3030. This Sound Blaster Pro derived card was factory installed in Tandy Multimedia PCs. It combined the CT1330 with Tandy joystick and MIDI ports (not MPU 401 compatible).

The Sound Blaster Pro 2 MCV, CT5330, was a version created for IBM PS/2 model 50 and higher and their MicroChannel bus.

The Sound Blaster ViBRA16 was an inexpensive single chip implementation of the Sound Blaster 16 for the OEM market. Creative Labs also used this chip for the Sound Blaster 32, Phone Blaster and Phone Blaster 28.8 (VIBRA plus modem, CT3120 and CT3220.) and many other value edition cards. External Yamaha OPL3 FM music synthesis was retained in earlier boards built around the ViBRA16 or ViBRA16s controllers, whilst the later (and more common) ViBRA16 boards used CQM (Creative Quadratic Modulation) developed by E mu Systems. This series included the ViBRA16 (CT2501), ViBRA16s (CT2502, CT2504), ViBRA16c (CT2505) PnP and ViBRA16XV (CT2511) chips. The primary advantage of the ViBRA16 was the inclusion of a 14.4 kbit/s telephony Modem; it also functioned as a telephone.

Released in March 1994, the Sound Blaster AWE32 (Advanced WavEffects) introduced an all new MIDI synthesizer section based on the EMU8000. The AWE32 consisted of two distinct audio sections; the Creative digital audio section (audio codec, optional CSP/ASP chip socket, Yamaha OPL3), and the E mu MIDI synthesizer section. The synthesizer section consisted of the EMU8000 sampler and effects processor, an EMU8011 1 MB sample ROM, and 512 KB of sample RAM (expandable to 28 MB). To fit the new hardware, the AWE32 was a full length ISA card, measuring .

A derivative of the AWE32 design, the Sound Blaster 32 (SB32) was a value oriented offering from Creative. Announced on June 6, 1995, the SB32 became the new entry level card in the AWE32 product line (previously held by the AWE32 Value.) The SB32 retained the AWE32's EMU8000/EMU8011 MIDI synthesis engine and built in instrument ROM, but dropped the onboard RAM, the Wave Blaster header, and the CSP port. The SB32 used the Vibra chip to reduce component count, which meant bass/treble/gain control was limited compared to the AWE32. The loss of onboard RAM is offset by the inclusion of 30 pin SIMM RAM sockets, which allow up to 28 MB RAM to be installed and used by the EMU engine.

The AWE32's successor, the Sound Blaster AWE64 (November 1996), was significantly smaller, being a "half length ISA card" (that term is misleading—see the pictures for size comparison). It offered similar features to the AWE32, but also had a few notable improvements, including support for greater polyphony, although this was a product of 32 extra software emulated channels. The 30 pin SIMM slots from AWE32/SB32 were replaced with a proprietary memory format which could be (expensively) purchased from Creative. The main improvements were better compatibility with older SB models, and an improved signal to noise ratio. The AWE64 came in two versions: A standard version (later rebranded as Value) with 512KB of RAM and a Gold version with 4 MB of RAM and a separate S/PDIF output.

In 1998, Creative acquired Ensoniq Corporation, manufacturer of the AudioPCI, a card popular with OEMs at the time. It was a full featured solution with wavetable MIDI (sample based synthesizer), 4 speaker DirectSound3D surround sound, A3D emulation, and DOS legacy support via a terminate and stay resident program. It was cheap due to lack of hardware acceleration. It is full duplex but at least in MS Windows cannot play back several sources at once. Creative released many cards using the original AudioPCI chip, Ensoniq ES1370, and several boards using revised versions of this chip (ES1371 and ES1373), and some with Creative labeled AudioPCI chips. Boards using AudioPCI tech are usually easily identifiable by the board design and the chip size because they all look quite similar. Such boards include Sound Blaster PCI64 (April 1998), PCI128 (July 1998), Creative Ensoniq AudioPCI, Vibra PCI and Sound Blaster 16 PCI. An ES137x chip contains three stereo sample rate converters, some buffers and a PCI busmaster interface. Analogue interfacing is done by a codec chip, which runs at a fixed sampling frequency of 44 (Ensoniq Audio PCI) or 48 kHz (Creative's versions). (ISA soundcards had not resampled but switched between different time bases.) ES137x do not support SoundFonts but a filter less MIDI engine with wavetable (sample table) sets of 2, 4, and 8MB size.

When the Sound Blaster Live! was introduced in August 1998, the use of a programmable digital signal processor in PC audio was not unprecedented, as IBM had already done that with cheap Mwave sound and modem cards and Turtle Beach with their professional Hurricane soundcards. The Live! was built around Creative's new EMU10K1 chip, which contained 2.44 million transistors and was advertised of processing a flashy 1,000 MIPS. The EMU10K1 (and its successors) did not use on card RAM/ROM storage for instrument samples, instead it used a PCI busmaster interface to access sample data stored in the host PC's system memory. A/D and D/A converters as well as analogue mixing is done by an AC'97 chip running at 48 kHz sampling rate. All members of the SB Live! family have at least four channel analog audio outputs and a 15 pin MIDI/Joystick multiport. For game titles, EAX 1.0 (and later 2.0) (environmental audio extensions, which briefly competed with the now defunct A3D 2.0) added hardware accelerated acoustic effects. The EMU10K1 provided high quality 64 voice sample based synthesizer (a. k. a. wavetable), with self produced or third party customized patches or "Soundfonts", and the ability to resample the audio output as input and apply a range of real time DSP effects to any set of audio subchannels present in the device. The first model and flagship of the SB/Live family was the SB Live! Gold. Featuring gold tracings on all major analog traces and external sockets, an EMI suppressing printed circuit board substrate and lacquer, the Gold came standard with a daughterboard that implemented a separate 4 channel alternative mini DIN digital output to Creative branded internal DAC speaker sets, a S/P DIF digital audio Input and Output with separate software mappings, and a fully decoded MIDI interface with separate Input and Output (along with on mini DIN converter.) The Gold highlighted many features aimed at music composition; ease of use (plug and play for musicians), real time loopback recording of the MIDI synthesizer (with full freedom of Soundfonts, and environmental effects such as reverb, etc. ), and bundled MIDI software. The mainstream model was the Sound Blaster Live! Like the Gold, the Live featured multi speaker analog output (up to four channels), and identical music/sound generation capabilities (without the bundled MIDI software and interfacing equipment.) Later versions of the Live!, usually called Live! 5.1, offered 5.1 channel support which adds a center channel speaker and LFE subwoofer output, most useful for movie watching. The Live! 5.1 could also use one of the 3.5 mm jack ports as an SPDIF out, which allowed the connection of an external decoder. Creative also released a Sound Blaster Live! Player 1024 edition, which is identical to the regular Sound Blaster Live!, but with the addition of some extra software.

The Sound Blaster PCI 512 (CT4790) is an EMU10K1 based sound card designed to fill a lower cost segment than the Live! Value. It is capable of most of the Live! Value's features aside from being limited to 512 MIDI voice polyphony (a software based limitation), lacking digital I/O, removal of expansion headers, and only stereo or quadraphonic output support. The card's circuit layout is somewhat simpler than that of the Live! series.

The Sound Blaster Audigy (August 2001) featured the Audigy processor (EMU10K2), an improved version of the EMU10K1 processor that shipped with the Sound Blaster Live!. The Audigy could process up to four EAX environments simultaneously with its upgraded on chip DSP and native EAX 3.0 ADVANCED HD support, and supported up to 5.1 channel output. The Audigy was controversially advertised as a 24 bit sound card. The EMU10K2's audio transport (DMA engine) was fixed at 16 bit sample precision at 48 kHz (like the EMU10K1 in the original Live! ), and all audio had to be resampled to 48 kHz in order to be accepted by the DSP (for recording or rendering to output.) Sound Blaster Audigy 2 (September 2002) featured an updated EMU10K2 processor, sometimes referred to as EMU10K2.5, with an improved DMA engine capable of 24 bit precision. Up to 192 kHz was supported for stereo playback/record, while 6.1 was capped at 96 kHz. In addition, Audigy 2 supported up to 6.1 (later 7.1) speakers and had improved signal to noise ratio (SNR) over the Audigy (106 vs. 100 decibels (A)). It also featured built in Dolby Digital EX 6.1 and 7.1 decoding for improved DVD play back. The Audigy 2 line were the first sound cards to receive THX certification. Sound Blaster Audigy 2 ZS (September 2003) is essentially an Audigy 2 with updated DAC and op amps. Audigy 2 ZS uses the Cirrus Logic CS4382 DAC together with the op amps and can produce an output SNR of 108 dB. There were a few slight printed circuit board modifications and 7.1 audio support was added. Sound Blaster Audigy 4 Pro (November 2004) was an Audigy 2 ZS with updated DACs and ADCs, the new DAC being the Cirrus Logic CS4398, boosting the output SNR to 113 dB. Other than a breakout box, it has no distinguishable difference from the Audigy 2 ZS. The DSP is identical to the Audigy 2 ZS's but Creative put an "Audigy 4" sticker to cover the chip, making it appear as if it is a new chip. The Audigy 4 Pro is not to be confused with the Audigy 4 (Value) which contains lower quality DACs and does not have golden plated jacks. The Audigy 4 (Value) is more in line with the Audigy 2 Value series. The Audigy 4 had a shorter life span than its predecessors, due to the short window between it and the next generation Sound Blaster X Fi. Sound Blaster Audigy Rx (September 2013) is similar to the Audigy 4 but with a dedicated 600 ohm headphone amplifier and a PCIe 1x interface. Sound Blaster Audigy Fx (September 2013) also features a 600 ohm amplifier and a PCIe interface, but lacks the EMU10K DSP.

The X Fi (for "Extreme Fidelity") was released in August 2005 and as of 2012 came in XtremeGamer, Titanium, Titanium Fatal1ty Professional, Titanium Fatal1ty Champion and Elite Pro configurations. The 130 nm EMU20K1 (or EMU20K2 for Titanium series models) audio chip operates at 400 MHz and has 51 million transistors. The computational power of this processor, i. e. its performance, is estimated as 10,000 MIPS, which is about 24 times higher than the estimated performance of its predecessor, the Audigy processor. Beginning with the 2008 Titanium models, newer X Fi cards switched from PCI to PCI Express x1 connectors. With the X Fi's "Active Modal Architecture" (AMA), the user can choose one of three optimization modes: Gaming, Entertainment, and Creation; each enabling a combination of the features of the chipset. The X Fi uses EAX 5.0 which supports up to 128 3D positioned voices with up to four effects applied to each. This release also included the 24 bit crystallizer, which is intended to pronounce percussion elements by placing some emphasis on low and high pitched parts of the sound. The X Fi, at its release, offered some of the most powerful mixing capabilities available, making it a powerful entry level card for home musicians. The other big improvement in the X Fi over the previous Audigy designs was the complete overhaul of the resampling engine on the card. The previous Audigy cards had their DSPs locked at 48/16, meaning any content that did not match was resampled on the card in hardware; which was done poorly and resulted in a lot of intermodulation distortion. Many hardcore users worked around this by means of resampling their content using high quality software decoders, usually in the form of a plugin in their media player. Creative completely re wrote the resampling method used on the X Fi and dedicated more than half of the power of the DSP to the process; resulting in a very clean resample.

The Recon3D series was announced in September 2011 and includes the Recon3D PCIe, Recon3D Fatal1ty Professional and Recon3D Fatal1ty Champion. The cards use the new integrated Sound Core3D chip, which features the Quartet DSP from the X Fi series as well as integrated DAC, ADC and I/O interface in a 56 pin package. The Asia only Recon3D Professional Audio is basically a Recon3D PCIe with some extra accessories such as cables. The Recon3D series of sound cards do not support ASIO. The Recon3D comes with a bundled software called the SBX Pro Studio. SBX Pro Studio allows users to adjust the amount of virtual Surround, Crystallizer, Bass, Smart Volume and Dialog Plus for their Recon3D sound cards. The Recon3D also has got the Crystal Voice feature that reduces the pickup of background noises like the hairdryer or vacuum cleaner when a beamforming microphone is used. Reviews have been generally positive, but pricing and small model differences have raised questions. Especially the low and mid priced models Recon3D PCIe and Recon3D Fatal1ty Professional have only cosmetic differences, but considerable price difference: the Fatal1ty Professional, adds a beamforming microphone, some red LED lights and a metal shroud over the board, but has no real hardware improvements.

The Sound BlasterX AE 5 was announced in June 2017, the first discrete sound card made by Creative in five years since the introduction of the Z series. The card is the first in the Sound Blaster series to use a 32 bit/384 kHz SABRE 32 Ultra DAC (ES9016K2M), along with a custom designed discrete headphone amplifier (1 W output power and low output impedance of 1 Ohm so it can provide high damping factor for virtually any dynamic headphone). The card has an additional RGB lighting courtesy of a MOLEX power connection and accompanying RGB LED strip. In late 2017, a white colored model of the sound card called the Sound BlasterX AE 5 Pure Edition was released with 4 RGB LED strips instead of one with the standard black model. In 2020, the AE 5 Plus was released which is similar to the previous model, but the sound card comes with hardware Dolby Digital Live and DTS encoding. There is a white colored Pure Edition released alongside the standard black model.

The Sound Blaster AE 7 was released in July 2019 alongside the Sound Blaster AE 9. and it features an ACM (Audio Control Module), which connects to the sound card via two of the audio ports available on the card itself. This soundcard is equipped with an ESS SABRE 9038 DAC, and it features an external Audio Control Module which connects to the sound card with a mini HDMI cable,

Sound BlasterAxx is a series of USB powered speakers that has the features of a sound card. The speakers also have built in microphones. The series of speakers work with Mac OS X other than Microsoft Windows.

The Sound BlasterAxx SBX series was released in year 2012. There are three models in the series, the Sound BlasterAxx SBX 8, Sound BlasterAxx SBX 10 and Sound BlasterAxx SBX 20. All three speakers have a bass port, Headphone Out and Aux in/Mic in 3.5mm jacks behind. The speakers do not contain rechargeable batteries and they require a USB power source. The speakers work with the Sound BlasterAxx control panel software for adjustment of SBX Pro Studio and Crystal Voice settings. The Sound BlasterAxx Control Panel has got a Mac OS X version other than the Microsoft Windows version. The Sound BlasterAxx SBX 8 is the only speaker that does not have Bluetooth capability. The Sound BlasterAxx SBX 10 and Sound BlasterAxx SBX 20 are Bluetooth capable and can be used for answering phones calls from iOS and Android smart phones. The Bluetooth version for the speakers is Bluetooth 2.1(Enhanced Data Rate). The Bluetooth codecs supported are SBC and AAC, aptX is not supported. The speakers also do not support ASIO and do not have the Scout Mode feature. SBX Pro Studio effects such as SBX Surround, SBX Crystallizer, SBX Bass, SBX Smart Volume and SBX Dialog Plus can be adjusted by the Sound Blaster Central mobile app.

In the beginning of 2014, Creative Labs released the Sound BlasterAxx AXX 200 portable Bluetooth speaker. Like the speakers of the Sound BlasterAxx SBX series, it has a built in SB Axx1 sound chip and works with both Mac OS X and Microsoft Windows computers. Its dimensions are 64.0 x 72.3 x 200.6 mm (2.51 x 2.84 x 7.9 inches) and it weighs 0.5 kg (1.1 lbs). The Sound BlasterAxx AXX 200 has a built in 5200mAh Lithium ion battery, allowing it to be used as a portable Bluetooth speaker. It has a microSD card slot for playing WMA/MP3 tracks from a microSD card. Calls and voices can be recorded through its microphone; the recordings are stored in the microSD card. It also has a megaphone function. Its Bluetooth version is Bluetooth 2.1(Enhanced Date Rate) and supports SBC, AAC and aptX Bluetooth codecs. It can be paired with Bluetooth devices via NFC(Near Field Communication). Same as the Sound BlasterAxx SBX series of speakers, it does not support ASIO and does not have the Scout Mode feature.

Some drivers from the Audigy 2 ZS have been soft modded by enthusiasts. These can be installed on Creative's older cards, including Sound Blaster Live!, Audigy, and Audigy 2. It has been claimed to offer improved sound quality, hardware acceleration of higher EAX versions in games, 64 channel mixing for Audigy 1, and an overall improvement in the card's performance. Several forum posts across the web have reported favorable results with this technique, excepting Live! users where the drivers only add the ability to use the newer software applications (i. e. the newer mixer applet). Comments on forums from developers of the software mod have said that Live's hardware is not capable of EAX3 nor 64 channels of hardware sound mixing. Later, in 2004, Creative released updated drivers top to bottom for the Audigy through Audigy 4 line that put these cards basically at feature parity on a software level. As of 2006, the entire Audigy lineup uses the same driver package. DSP decoding at the driver level on other cards than Audigy 2 ZS and 4 is still not supported by official drivers, but it works with soft modded drivers on the other cards with hardware DSP (like Audigy 2 6.1). When Windows Vista was released, there was only a single beta driver for the Creative Audigy series that was usable on the operating system with minimal functionality and frequent instability reported by users. A Creative Forum activist named Daniel K. modified drivers from the X Fi and applied it to the Audigy and Live! series, restoring most if not all of the features that came with the original XP setup CD in Vista. X Fi drivers have noticeably better sound quality under Vista, and more bug fixes because of the newer build (last modified version is 2.15.0004EQ April). He managed to enable the X Fi Crystallizer to work on Audigy series cards in software, however because of the patents involved, he was forced to remove all the modified drivers and DLL patch. Creative then released a newer official Audigy Vista driver (2.18.0000 as of 28 July 2008) due to public and consumer pressure. However, some form of agreement between Creative and Daniel K has been achieved, as he returned to the Creative forums, posting updated versions of his modified drivers. He released the final version of his modded driver package as of January 12, 2012.

All recent Linux distributions support Sound Blaster Cards via kernel drivers. In case of non Plug and Play ISA cards, a configuration file in must be reconfigured, writing for example with Sound Blaster 16 card installed:
X Fi series cards have basic support in Linux, but the advanced features like signal routing, relay control or external I/O consoles are not supported. Support for the newer Sound Blaster cards (Z and AE series) was added to the kernel during 4.19 – 4.20 release timeframe.
