Cmi9739a Sound Driver For Mac
Hilke Mcnally
I downloaded this driver right from the manufacturer of the audio chip. I have a Biostar M7VIP ver. 1.1 motherboard and WindowsXP had trouble installing the drivers that came with it. This driver installs support for 2, 4 or 6 speaker output. Simply download the file and double-click on it. It will install and ask you to restart your computer. Works great!
If the driver listed is not the right version or operating system, search our driver archive for the correct version. Enter CMedia 9739A into the search box above and then submit. In the results, choose the best match for your PC and operating system.
Once you have downloaded your new driver, you'll need to install it. In Windows, use a built-in utility called Device Manager, which allows you to see all of the devices recognized by your system, and the drivers associated with them.

What would you guys suggest? A new soundcard? What should it be? Or a combo with anything else? Do any of you have any hardware-related docs, a detailed datasheet, for example?
So, the general preliminary product concept will be as following:
IMO biggest drawbacks of Vortex cards were rather related to drivers, especially for DOS and Win 2k+. There was a promising thread in this forum dedicated to development of an alternative DOS driver - not many recent updates unfortunately, however, some documentation is mentioned there, and the topic starter may also have deeper understanding of the subject.
Speaking about hardware, I'd also say that Aureal's simulated FM synthesis sounds pretty poor (way worse than CQM), if no beter driver - here is the place where true OPL could be even more beneficial. Compatibility could be also improved: original cards are quite picky to PCI slots and prone to conflicts with other adapters, and I still recall pain with VIA chipsets 20 years ago, though already w/o details.
Well, in the past I already considered making an "Ultimate" PCI sound card (YMF7x4+AU8830 behind a PCI bridge, interconnected via SPDIF) but finally decided to discard that. In my perception, AU8830 is only useful in A3D 2.0/3.0, it's where it shines. It won't suit for a good DOS card (there are better options, YMF7x4 and Solo-1), or an audiophile grade card, and would make for a mediocre all-round card due to the mentioned bad FM implementation, buggy Win2K/WinXP drivers, compatibility problems. So, to be honest, AU8830 should be used only in Win9x (so, no SMP or 512+ Mb of RAM), for playing A3D titles (but hey, there are lots of them, and many of them are A+ ones!), so the CPU power should be decent too (P3-600 at least) as A3D has its impact on the performance. That's why I'm thinking about this specific A3D Accelerator niche.
The chip has I2S input and output, you could simply drop the shitty codec chips and use modern DAC and ADC instead (lacking mixer though). There's probably some driver change needed to achieve it though...
Hello, this is one of my first topics in MSFN, one of the things i've considered posting is about Windows 95 onboard AC97 audio drivers and inf mods which were needed in some drivers (had to do for some systems). Also to recopilate them as well
The inf modded versions are made due to some AC97 driver packages for Windows 95 (notably Realtek and C-Media), deliberated cut support for many chipset AC97 controllers in the Windows 95 version, but supported in the Windows 98/ME/2000/XP versions even if the driver version is the same as the later one, the mod puts the HW support in the Windows 95 version on par with the Windows 98/ME/2000/XP version
I could not record any sound from my microphone. It has a 3.5mm jack plug that I pug into the standard microphone socket on the front face of my PC box. I use the Sound Recorder software that is native to Windows XP Home Edition (and native in all versions of Windows from Windows 98 onwards).
From here, I went to the C-Media website to download the right driver software. From this point, I thought things would get better. On the other hand, doubt began to creep in because as I was installing the software it prompted me whether to overwrite a few files. Some files on my PC were newer than the ones in the driver file I had downloaded. Er? So I said No to these choices and left the newer files in place. After intalling the software I was prompted to restart my PC, which I did.
MSI chose C-Media's CMI9739A controller chip to output the SiS 963's AC'97 sound. This basic DAC will be able to output satisfying sound for the vast majority of users out there, but avid gamers will look to add-in sound cards such as Creative Lab's Audigy or the Turtle Beach Santa Cruz.
The 655 Max doesn't use a particularly interesting I/O configuration compared to most boards, but it's certainly acceptable nonetheless. Included are two PS/2 ports, two serial ports, one parallel port, four rear USB 2.0 ports, one Gigabit LAN port, and three 1/8' jacks, which are driven by the onboard sound. This will adequately meet the needs of most enthusiasts, though it would have been nice to see an I/O configuration similar to ABIT's MAX series.
A sound card (also known as an audio card) is a computer expansion card that facilitates the input and output of audio signals to and from a computer under control of computer programs. Typical uses of sound cards include providing the audio component for multimedia applications such as music composition, editing video or audio, presentation, education, and entertainment (games). Many computers have sound capabilities built in, while others require additional expansion cards to provide for audio capability.
Sound cards usually feature a digital-to-analog converter (DAC), which converts recorded or generated digital data into an analog format. The output signal is connected to an amplifier, headphones, or external device using standard interconnects, such as a TRS connector or an RCA connector. If the number and size of connectors is too large for the space on the backplate the connectors will be off-board, typically using a breakout box, or an auxiliary backplate. More advanced cards usually include more than one sound chip to provide for higher data rates and multiple simultaneous functionality, eg between digital sound production and synthesized sounds (usually for real-time generation of music and sound effects using minimal data and CPU time). Digital sound reproduction is usually done with multi-channel DACs, which are capable of multiple digital samples simultaneously at different pitches and volumes, or optionally applying real-time effects like filtering or distortion. Multi-channel digital sound playback can also be used for music synthesis when used with a compliance, and even multiple-channel emulation. This approach has become common as manufacturers seek to simplify the design and the cost of sound cards.
Most sound cards have a line in connector for signal from a cassette tape recorder or similar sound source. The sound card digitizes this signal and stores it (under control of appropriate matching computer software) on the computer's hard disk for storage, editing, or further processing. Another common external connector is the microphone connector, for use by a microphone or other low level input device. Input through a microphone jack can then be used by speech recognition software or for Voice over IP applications.
An important characteristic of sound cards is polyphony, which is more than one distinct voice or sound playable simultaneously and independently, and the number of simultaneous channels. These are intended as the number of distinct electrical audio outputs, which may correspond to a speaker configuration such as 2.0 (stereo), 2.1 (stereo and sub woofer), 5.1 etc. Sometimes, the terms "voices" and "channels" are used interchangeably to indicate the degree of polyphony, not the output speaker configuration.
For example, many older sound chips could accommodate three voices, but only one audio channel (ie, a single mono output) for output, requiring all voices to be mixed together. Later cards, such as the AdLib sound card, had a 9 voice polyphony and 1 mono channel as a combined output.
For some years, most PC sound cards have had multiple FM synthesis voices (typically 9 or 16) which were usually used for MIDI music. The full capabilities of advanced cards aren't often completely used; only one (mono) or two (stereo) voice(s) and channel(s) are usually dedicated to playback of digital sound samples, and playing back more than one digital sound sample usually requires a software downmix at a fixed sampling rate. Modern low-cost integrated soundcards (ie, those built into motherboards) such as audio codecs like those meeting the AC'97 standard and even some budget expansion soundcards still work that way. They may provide more than two sound output channels (typically 5.1 or 7.1 surround sound), but they usually have no actual hardware polyphony for either sound effects or MIDI reproduction, these tasks are performed entirely in software. This is similar to the way inexpensive softmodems perform modem tasks in software rather than in hardware).
