The Daily maintenance and maintenance skill of computer sound card

Everyone may have encountered a sound card has no sound problem, some people may think it is their own sound card is not used, in fact, there are many aspects of the reason, as long as we pay attention to these problems will be able to avoid sound card without sound problem, we did a little summary.

If your sound card does not make a sound, there are several common reasons for this:

1, the speaker is not open, please open it.

2, the speaker socket is not properly installed, please install accurately in the speaker socket.

3, sound card driver missing Please reinstall the sound card driver. (The driver for your sound card is easily lost).

4, sound card and other board conflicts please set the sound card set values correctly.

5, the sound card troubleshooting the above items only after the sound card itself has failed, please replace the new sound card.

In the CPU, motherboard, graphics and other large parts, purchase is not ambiguous. And in the sound card and other small parts of the purchase, but is a totally, can feel 2, 300 yuan to buy a sound card even if very generous. Most don't pay for a sound card--An integrated AC ' 97 soft sound card on the motherboard. However, some of the so-called computer experts on such a white card to send a high demand for the poor, it has been repeatedly condemned.

1, what is the AC ' 97 soft sound card?

People often put AC ' 97 as a synonym for sound card, in fact, this is a misunderstanding of the understanding. This year, multimedia technology has become increasingly popular and widely used on personal computers. In order to be able to provide high-quality, low-cost sound architecture on the PC. In June 1996, Intel, Creative Labs, NS, analog device and Yamaha, led by Intel, presented Audio Codec ' 97 (AC ' 97, meaning "audio multimedia digital Signal codec") for five PC manufacturers. of the specification standard. The biggest innovation is the "dual-chip" structure that allows the conversion of ADC (Analog-to-digital conversion, analog to digital) and DAC (Digital-to-analog conversion, digital analog) to be as detached from the system as possible, This avoids the clutter generated by the conversion of most digital/analog signals, resulting in better sound quality.

At present all of the sound cards are supported by AC ' 97. It is not simply referring to the integrated soft sound card on the motherboard. And the AC ' 97 soft sound card is another concept. It is just a codec chip based on AC ' 97, no digital audio processing unit, so when the computer plays audio information, except D/A and A/D conversion all the processing work should be handed over to the CPU to complete. It can be said that the AC ' 97 soft sound card simply simplifies the hardware, while the design idea is still implementing the AC ' 97 specification standard of the sound card. The current AC ' 97 soft sound card has analog devices ad188x (AD1881, AD1885, AD1886), alc201/a, VIA vt1611a.

2, AC ' 97 really that bad?

If you ask a friend who understands computers: How about AC ' 97 soft sound cards? They almost always unanimous. Why? The author concludes the following reasons.

A. High CPU usage

Because the AC ' 97 soft sound card is only responsible for D/A and A/D conversion, and most of the work to be done to the CPU, so ghost XP SP3 system resource occupancy rate also increased. This is a fatal wound before the CPU performance is low. When playing a large 3D game, using an AC ' 97 soft sound card can cause problems such as slowing down, skipping frames and even Huati. This left a terrible impression on many people (AC ' 97: It's not my fault, ~~!). However, this does not seem to be a problem at the moment. CPU's frequency war also enters the climax, the CPU's frequency is flourishing, the newest PENTIUM4 's frequency is up to 2.6G, and the tallest athlonxp also has reached the 1.667G, has the frequency so high CPU to do the backing, the AC ' 97 looks can be relieved. This is like a soft cat, when the CPU performance rapidly increased, occupy the point of resources enough to let people accept, because of this reason, many users slowly accept the cheap and soft cat, I believe the AC ' 97 soft sound card will be the same.

B. Poor sound quality

It is often said that the AC ' 97 soft sound card is just a thing that makes the computer make noise, which is blamed for its poor sound quality. AC ' 97 does not have the same sound quality as those of high-end sound cards. After all, it's free. But compared with those 100 or 200-yuan sound card, the gap is not so wide. The signal-to-noise ratio (SNR) of all AC ' 97 soft cards can reach more than 75dB. Despite the clutter from the electronic components around the motherboard, the problem is negligible on a highly skilled motherboard.

Small knowledge: Signal-to-noise ratio (snr,signal to noise Ratio) refers to the signal and no signal inherent noise, the performance is generally the background noise. The ratio of strength to common logarithms is multiplied by 10, the Unit is DB (db). When the signal-to-noise ratio is below 75dB, the noise may be detected in a quiet environment, while playing music is not obvious. When the signal-to-noise ratio reaches around 95dB, it is difficult to hear the noise of the human ear.

The Gospel of C.ac ' 97 soft sound card

As you can see, the AC ' 97 soft sound card in the current situation, although the "cheap", but at least not the "beauty of things" category. But now it's okay, many AC ' 97 soft sound card users can make an upgrade free of charge, making it a great, high-performance sound card (as opposed to those cheap sound cards). What can have this kind of mana? That's the drive.

Soundmax 3.0

Soundmax 3.0 is a joint release of analog devices and Intel, which is suitable for a full range of analog soft sound cards (although claiming to support only AD1885, you can support a full range of Smwdm.inf sound cards by modifying ad188x files). Enables the AC ' 97 soft sound card to have the hardware level data processing conversion ability and the highest 94dB professional sound playback ability. Soundmax 3.0 has become an outstanding representative of the AC ' 97 high performance solution for Soft sound cards. With Soundmax, we can make our cheap AC ' 97 soft sound card emit high quality 3D sound and excellent midi compositing effect. Soundmax 3.0 in the use of Sensaura for 3D positioning sound, midi soft wave table is the use of XG compatible with the SONDIUS-XG, as long as the computer performance is sufficient, soft wave table at the same time there is no limit to the number of sound. It is worth mentioning that a new sound algorithm, SPX, is added to Soundmax 3.0, which allows the game to use this algorithm to change the infinite sound, even if the same game situation will be due to a few different factors to produce each of the different sound changes, the game is not a static sound, and the fun increases. But so far, the games that support SPX are still in the minority, and that doesn't matter, Soundmax 3.0 is also compatible with the current popular audio APIs, including Microsoft Directsound/directx 8.0, Aureal A3D 1.0, EAX 1.0 and 2.0 and many of the sound features we don't know.

Realtek alc201/a AC ' 97

In SoundMAX3.0 red through the sky, Realtek for alc201/a tailored a driver, in effect, the slightest less than the Soundmax 3.0. It also enables alc201/a to have a hardware-level data processing conversion capability and a maximum of 95dB Snr, as well as an improved CPU occupancy rate. At the same time with up to 26 kinds of environmental effects for users to choose. Use alc201/a soft sound card friend, don't miss Oh!

The new driver not only reduces CPU occupancy, improves sound quality, but also enables the AC ' 97 soft sound card to fully support three-dimensional sound and midi wave-table synthesis. In addition, due to the specificity of the AC ' 97 soft sound card. The chipset manufacturers will spare no effort to support the advent of these two excellent drivers, should change the AC ' 97 soft sound card in the hearts of the poor impression of the people. Believe that the manufacturers will continue to introduce a better driver.

D.Ac ' 97 soft sound card for which users?

Ordinary users If your audio application is just listening to MP3, playing ordinary games, then money to buy a sound card will inevitably some waste. The AC ' 97 soft sound card can fully meet your needs. One might say that the AC ' 97 soft sound card has a poor quality, unless you have the golden ear of the Master of Music, you will not be able to hear the difference between an AC ' 97 soft sound card and an upscale sound card. DIY to pay attention to "practical, adequate", money to spend on the blade.

Game users now many games, especially the CS-represented FPS game, in the graphics requirements, sound effects have become very important. Listening to the voice of the card will require a strong sound and positioning ability. In this regard, in addition to SB live and Aureal series of sound cards, many low-cost sound card can not achieve good results. The AC ' 97 soft sound card does not have this performance. But a strong drive does give it a powerful impetus. For example, AD1885 installed on the Soundmax 3.0, in the CS in the sound and positioning effect, compared to the CMI8738 and other low-cost sound card much better. But if your last name is Channado, go and buy Creative's top-grade sound card, which is more suited to your needs.

E. What do we think of the AC ' 97 soft sound card?

Because of the high CPU occupancy rate and poor sound quality, resulting in AC ' 97 soft sound card from the birth to the present, is a synonym for inferior. Although the CPU speed is increasing, Soundmax 3.0, Realtek drive to varying degrees in the day after tomorrow to make up for AC ' 97 soft sound card defects. However, using the AC ' 97 soft sound card can still slow down the system at a high load. However, the AC ' 97 soft sound card is a relatively affordable solution for ordinary users and game users in general. By driving, we can completely turn a free sound card into a hundreds of yuan worth of sound card. And this process is completely free of charge. If there are still people say that AC ' 97 soft sound card is chicken, nothing, then his mind is too old.

Through our today's explanation, you probably all learned about the concept of sound card technology, so later in the purchase of sound card and use of the process should be noted that we must notice.
