I need a DOS driver for the ADI AD1881 audio codec, using an ISA soundcard is sadly not an option on this particular machine... it looks like SoundMax (Analog Devices) only sold the chip, no drivers. all the OEMs seem to have broken links to their DOS drivers (Damn you HP) but its an Acer board. although its not the mobo that matters, its the codec itself.]
I know I am necroing this post but I have a laptop with the same audio chipset that I think I'd like to run just pure DOS on. Has there been any updates to this? Anyone thing the DOS AC97 driver would work?
AC 97 is all called "Audio Codec 97", meaning "audio multimedia digital Signal codec". This is by Intel, analog devices and other related manufacturers to develop the audio circuit system standards, and has been widely recognized by the industry. AC 97 is a technical specification, in short, it employs a dual-chip architecture that allows ADC and DAC to remain relatively independent as far as possible, in order to reduce interference and improve sound quality. Now on the market of multimedia sound card, in addition to CMI8738, and so on a few exceptions, mostly follow the AC 97 standard, including the famous innovation Sound Blaster live! series sound card. I would like to clarify here that many friends treat the AC 97 sound card with the soft sound card, or confuse the AC 97 sound card with the motherboard integrated sound card, in fact these are not correct. As we have seen from the above definition of the AC 97 sound card, it represents only an audio processing technology, an abstract specification, not a specific sound card product category. So the so-called AC 97 soft sound card, refers to the use of CPU to replace the traditional hard sound card audio processing chips for a variety of voice processing work, and then the processing of digital signals to external DAC or onboard codec (hardware decoder) output of a class of products. From the current situation, the AC 97 soft sound card is mainly integrated with the main board, but also similar to the traditional hard sound card as the appearance of independent board face products, this kind of products mainly using CNR interface, like the Ruili company launched the Cnr-soundmax sound card, using 3 AD1885 Codec work together to achieve 6-channel output effect; many companies, such as Hercules, have similar products. On the other hand, the motherboard integrated sound card is not necessarily an AC 97 soft sound card, even not necessarily AC 97 sound card, the former such as innovative ct5880/es1373, etc. belong to the motherboard integrated AC 97 hard sound card, such products in addition to the sound chip, on the motherboard will also be integrated with a codec chip , such as CMI8738, etc. also belong to the motherboard integrated hard sound card, but it does not meet the AC 97 technical specifications, so there is no additional integrated codec chip. In fact, other than having no sound processing chip, the other hardware components of the AC 97 soft sound card do not differ from the working principle and the AC 97 hard sound card. For AC 97 soft sound card, the factors that affect its performance may have a lot of, but in particular, the type of codec chip, PCB wiring of the pros and cons of the corresponding driver and the degree of perfection is most important. In these three key elements, the codec chip responsible for DA, AD (analog-to-digital/modulus) conversion determines the type of driver used, so many people tend to use the codec model as the AC 97 soft sound card model. One might worry that the quality of an AC 97 soft sound card can be compared to a traditional hard sound card by eliminating the traditional sound-processing chips and relying on software simulations and CPU operations. At the same time CPU resource occupancy rate will be high? In fact, there is absolutely no need for us to worry about this. In performance, the traditional hard sound card can certainly rely on its high-speed DSP chip to obtain a certain performance advantages, but now the CPU performance has been more powerful, to Soundmax as the representative of the audio processing technology and the corresponding driver has been increasingly mature, in this case, AC 97 soft sound card not only in the sound quality can be fully guaranteed, but also because of the characteristics of software simulation can have almost unlimited upgrade potential: Imagine, if a sound card manufacturers launched a landmark new sound card, then you can take its driver directly to their old sound card upgrade it? and AC 97 soft sound card has no such concern, hit a oundmax for example, from the 2.0 version to 3.0 version of the progress, its amplitude is no less than innovative Audigy to SB live! upgrade, and we have to do is simply in support of Soundmax 3.0 technology AC 97 soft sound card on the change driver only! So, what is Soundmax technology? And those AC 97 soft sound cards support this technology? Please keep looking down.
Similar to the technical specification of AC 97, Sounmax is also a technical specification--to put it more in detail, a sound card technology based on the AC 97 specification "Implementation Details". However, with the AC 97 "soft and hard take-all" approach is different, Soundmax technology is born to sympathize with the "soft" weak, special attention to explore the potential of codec chips, with hardware-level data processing conversion capabilities and the highest 94dB professional sound playback ability, is mainly for AC 97 soft sound card support technology Solutions This technology solution has been developed for Soundmax with SPX (sound product extension) technology, referred to as Sound MAX 3.0 technology. The Soundmax 3.0 technology was developed by analog devices and Intel, with the greatest feature being the integration of the SPX audio effect algorithm. The algorithm mainly improves the sound effects of 3D games, built-in physical modeling, event modeling, and also has the technology of digital signal processing of soft DSP which can be upgraded. SPX technology can simulate the real-time sound effects of 3D gaming scenes flexibly and realistically, this dynamic algorithm allows the game to support it to change the infinite sound, even the same game situation will be due to a few different factors and produce random sound changes, the game is no longer the same sound, the fun will increase. In addition, the Soundmax 3.0 technology also has the following characteristics:
As long as the user has a motherboard (including i810/i815/i820/i830/i840/i845/i850, etc.) with a i810 or later chipset, and the codec chip model on the motherboard is AD1885 or higher, you can install Soundmax directly 4.0 were driven. And the Via VT8233 Bridge chip and SIS chipset integrated audio Controller has the highest priority, for motherboards using such chipsets, codec chip only play the role of decoding, so the Soundmax 4.0 driver can not be applied. Motherboards like the Via KT266 (A)/via Apollo pro266/sis 630/sis 635/sis 735 chipset are not available at all 730/sis MAX 4.0, and other non-Intel chipsets can be problematic even when installed. , so it is not recommended.
There is a lot more to a sound card that can affect audio quality than just these three, but as the core components, they certainly set the baseline for a sound card's capabilities. There are about 107 different ICs mentioned, including drivers and datasheets where I have managed to find them. In some cases, I have also included the original press release.
The job of the audio codec ("COder-DECoder") is to encode and decode a digital stream of data or signal, working in conjunction with the DAC (see further down this page). Below is some information on the more common codec chips found on PC sound cards.
They had an integrated OPL3-SA3 for backward compatibility to Ad Lib, Sound Blaster, Sound Blaster Pro and Windows Sound System, and also have the same MPU-401-compatible interface for external General MIDI synthesizers. In addition, the YMF724 includes a 64-voice GM/DS-XG wavetable synthesizer with 2-channel output, interface to AC'97 codec, S/PDIF output, a Dolby AC-3 decoder, and 3D positional audio via DirectSound3D and QSound.
It also gets a built-in third-generation 16-bit Sigma-Delta codec by ECTIVA, which is further integrated with a low distortion complex mixer featuring 3D audio expansion. The OPTiSound 82C933 produces a spatial or widened stereo image from ordinary left and right channel inputs, without any initial encoding of input signals.
Cirrus Logic, Inc. produced some of the highest quality audio codecs, mainly used in home theatre receivers. In 1991 they acquired Crystal Semiconductor, a supplier of analog and mixed-signal converter ICs. The Crystal codecs were then marketed as Cirrus Logic's budget line. All these codec chips have the prefix "CS".
One of Crystal's first audio codecs for sound cards, introduced in 1993.16-bit input resolution.Not full duplex. Up to 50 kHz maximum input sampling rate. This is a clone of Windows Sound System. Found on:
codecs and exact hardware identifier. As mentioned above, HDA is only part of the work here, it gets the audio out of the main chipset in digital format (on a bus called I2S). This is not enough, there is another step needed which is routing that I2S signal to the output, converting it to actual audio, amplifying it, etc. This is handled by a separate chip called a "codec". Sometimes it is initialized by the BIOS, but this is not always the case.
Most audio drivers are made up of two parts a Controller + a Codec. The ProductID and VendorID are for the audio controller only - the important additional codec is NOT so easily identified. Some newer versions of existing codecs are missing at the moment.
Displaying 2D windows supports device-specific 2D drivers as well, but nowadays most of these are no longer needed as the modesetting can handle most hardware on its own. As the DRM/DRI got some additional interfaces for what used to be hardware-specific (setting resolutions, refresh rates, etc) and software requiring accelerated 2D drawing was optimized OpenGL-based renderers, dedicated 2D acceleration is slowly going away. Since around 2012, the 3D part of the graphics card deals with 2D operations. 2b1af7f3a8
