Integrated sound card can not drive

Q: My motherboard integrated AD1881A sound card, install the driver several times, always can not be used, what is the sound card driver installation problem or a problem?

A: Even with the same AD1881A sound chip, but some motherboards use some version of the driver is still not compatible to happen, and if the driver did not install the new driver to uninstall the old version, then the two will often conflict, resulting in the sound card does not work. Therefore recommend that you download some version of the SOUNDMAX driver installation, and if not compatible with other versions to change, here to remind you, not the new version of its compatibility with the more the better, sometimes the opposite. Dell latitude d520 adapter Driver to install the new version, be sure to uninstall the old version of the driver after the installation, or prone to driver conflict.

Why reduce the CPU frequency

Q: My computer configuration is: Athlon XP 1800 + CPU, Jetway J-V400 MAX (Digital Dragon) motherboard, Colorful GeForce4 MX440-8 × graphics card, 256MB DDR266 memory. Remember the Athlon XP 1800 + should be the actual frequency of 1.53GHz, why the boot show my CPU clocked at 1.15GHz?

A: Athlon XP 1800 + FSB is the standard work of 133MHz, the multiplier is 11.5, if you set 100MHz FSB, then display the frequency is 1.15GHz for granted, as long as the FSB set to 133MHz, or use the default board CPU frequency identification mode, the boot will show clocked at 1.53GHz.

No reason to restart the system to play games

Q: My NIKON EN-EL14 battery computer configuration is: P4 1.6GHz, Asus P4B266-C motherboard (i845D chipset), 128MB DDR RAM +256 MB Transcend Millennium GeIL DDR RAM, ASUS V7100 PRO/416 graphics, innovative Audigy sound card, IBM 60GB hard drive, operating system is Win XP, anti-virus software installed KV2004. Computer applications in general normal, but running “Need for Speed V Porsche Tour”, the phenomenon appears no reason to restart, re-install the system after the phenomenon remains the same, and play other 3D games there have no reason to restart the phenomenon. First suspected memory problems, respectively, using a single memory into the system, play the game will restart for no reason. Is this why?

A: If you exclude the memory of the reason, I suggest you look at cards, in general, applications do not crash the computer, play 3D games in the crash, most likely because the game play graphics chip overheating, please check the card’s cooling system to see if there is no problem. In addition, some components such as memory card problems when playing games may be abnormal, causing the system crash or restart, you can replace the method used to test the stability of what graphics card, thus eliminating the problem.

Cause abnormal display

Q: I just bought back a second hand Panasonic PF70 CRT monitors, in the normal business at the trial. Take home a few days, there has been slow after boot display phenomenon, that is just getting machine monitor screen is black, into the system for a while, the ACER aspire 5630 adapter display only light up. What is the reason?

A: The symptoms from the above analysis, the circuit part of your display problems, resulting in this failure may be due to the phenomenon of aging of the display tube socket, or anode circuit component aging, resulting in warm-up time is too long, this is due to circuit aging is not the result of aging CRT. In order to determine the monitor, you can also try to replace a normal display. Because the display is a high integration of electronic equipment, coupled with high-pressure work, it is recommended not to demolish their own maintenance, to the repair shop for repairs.

Hard to read long bright light causes

Q: My computer is turned on, even for a long time (eg 20 minutes) do nothing, the hard disk light is lit to read, just run the program than the brightness low, slightly shiny. Other friends of the computer does not operate when the length of the hard disk light does not light reading, and how is this going?

A: The SONY NP-77 Battery hard drive does not work under normal circumstances, the hard disk light is not shining to read. From the description of the situation, estimated background programs running, and these background programs do not rule out similar Trojan programs. Also, if you open the BIOS hard drive’s health status monitoring feature, hard drives will be conducted from time to time the state of their own self, so that the hard disk can also cause intermittent flashes.

1. With effective anti-virus software killing the virus to see if a virus like Trojans;
2. Enter the BIOS, check if the monitoring function of hard drive options, there are closed; 3. If the problem is not resolved, please check the manual control switch signal line and the board is properly connected;
4. If not, work hard for a try, should be able to solve the problem.

Issues related to Intel Hyper-Threading Technology

Q: Intel 865PERL board whether to support Intel Hyper-Threading Hyper-Threading Technology? Dual-channel technology and Hyper-Threading Technology Hyper-Threading What is the relationship? Is not any support for 800MHz FSB motherboard to support Hyper-Threading Hyper-Threading Technology?

A: Intel 865PERL i865PE motherboard chipset, supports Hyper-Threading Hyper-Threading technology. Hyper-Threading Dell latitude e5500 adapter CPU needs CPU, motherboard chipset, operating system and other aspects of support, whether the motherboard supports Hyper-Threading technology is used by the motherboard chipset decision, rather than determined by the front-side bus. Therefore supports the 800MHz FSB motherboard may not support Hyper-Threading technology. Technology is a dual-channel memory controller technology, Hyper-Threading technology and it is no direct relationship.

The use of SATA drives in Win98

Q: My computer configuration is: Intel original motherboard 865PE, Seagate 7200.7 SATA hard drive, install Windows 98SE, in the “Device Manager” in the “hard disk controller,” before the exclamation mark appears, and can not find the drive, but in Win there is no problem under XP. What is the reason?

A: This is because the original motherboard Intel 865PE SATA hard drive with Win 98SE to use, you need some settings in the BIOS, the system can correctly identify the SATA hard drive. In Win XP system is not set in the BIOS directly using the NIKON EN-4 Battery BIOS to default values. After entering the following BIOS settings (BIOS version P06 for example): Click the “Advanced” → “Drive Configaration” → “ATA / IDE Configaration” → “Legacy IDE Channels”, its value is set to “SATA P0/P1, PATA PRI “, the” PCI IDE BUST MASTER “is set to” ENABLE “, the” HARD DISK PRE-DELAY “is set to” DISABLE “, IDE to SATA hard drive options all set to” AUTO “.

Athlon XP 1800 + overclocked to test the impact of

Q: My computer’s CPU is the Athlon XP 1800 +, running 3DMark2001 SE score of 8284; overclocked to Athlon XP 2500 +, running 3DMark 2001 SE score of 9306, compared with Barton core Athlon XP 2500 + score lower, is not overclocked The Athlon XP 1800 + is not able to achieve the performance of Athlon XP 2500 + it?

A: Your Athlon XP 1800 + The secondary cache is 256KB, and the Barton core Athlon XP 2500 + The secondary cache is 512KB, even if the Athlon XP 1800 + overclocked to 2500 +, the secondary cache is 256KB, so its performance keep up with Barton core Athlon XP 2500 +. The CPU’s performance on tests of 3DMark2001 SE is great , graphics cards (Graduation Photo Taking Skills) and other accessories in the same circumstances, with Barton core Athlon XP 2500 + system, its 3DMark2001 SE score of positive tests than with Athlon XP 2500 + (by the Athlon XP 1800 + overclocked from) the system high. So overclocking Although you can improve system performance, but due to hardware limitations imposed, the general can not be overclocked to reach the same level of hardware performance levels.

Sound card technical knowledge

1, the advanced interfaces.

First PCI sound card to sum up the new technology. PCI sound card to say the previous ISA sound card with the biggest difference is that they used to transmit different data bus, ISA sound card’s name suggests, with the ISA bus is a traditional bus. This bus has been extended by a few decades, many of its drawbacks, the biggest drawback is its low bandwidth, the transmission rate only 6MBps, while providing up to 133MBps PCI transfer rate is 20 times the ISA. Sound card with PCI interface, the maximum data transfer rate of 133MB / s, while the ISA sound card interface transfer rate is only 6MB / s, which unlike the ISA sound card PCI sound card as a result of the data bandwidth of the system is running low and become a “bottleneck . ” With PCI interface card can realize more technology features, which can be stored wave table samples of the hard drive in the system, with the higher bandwidth of PCI is to use that take, which makes the wave form greatly reduce the cost of the sound card.
In terms of plug and play, SONY np-fw50 battery PCI sound card is also much better than the ISA sound card, it is because of this, the new PC98 standard ISA bus design has been canceled, the upcoming new BX motherboard is necessary to cancel the ISA slot, then, You want to use ISA sound card has a chance to use it!

2, excellent sound and high signal to noise ratio.

PCI sound cards typically have higher signal to noise ratio (most up to 90dB), some as high as 195dB or more. Higher signal to noise ratio to ensure that the sound output when the sound is more pure, noise can be reduced to a minimum. The sound is good or bad depends on the product chip and the selected sound card work. If possible, purchase a good idea to the lyrics sound card, of course, now when we buy the sound card does not have to audition generally, but if we buy a sound card, you can listen carefully this card’s effect If he felt bad, might get back to replace it.

3, MIDIl playback

MIDI is the acronym for Musical Instrument Digital Interface, the background music in the production of computer games has a wide range of applications. IBM thinkpad x60s battery MIDI file itself does not contain said auditory characteristics of the sound waveform data, it just records a series of performances of digital information and control of events triggered by MIDI commands, so its effectiveness depends largely on the play used playback MIDI Synthesis device. One of the advantages of PCI sound cards can use the advanced DLS (DownLoadedSound) technology, the sound wave table stored in the hard disk, through the sound card chip processing, transferred to the memory when playing MIDI. This will not only provide a good synthesis results MIDI wave table can be removed from the sound card on the ISA must be equipped with a sound library memory, reducing production costs. In addition to high-capacity wave table MIDI synthesis of good results also depends on the sound card wavetable synthesis chip supports the maximum polyphony.

4,3 D sound support

ISA, many times advertised “3D Audio” sound card, but smaller bandwidth ISA sound card interfaces, and its three-dimensional sound processing and playback capabilities are very limited. It can be said, 3D sound field is the introduction of a sound card into the SONY NP-FC11 Battery PCI era of technological breakthroughs. PCI sound card products currently support 3D sound into two, A3D (AurealSemiconductor development of a breakthrough interactive 3D positional audio technology) and EAX (Environmental Audio Extensions environmental audio extensions, the main duty is to serve the game by adding 3D reverb .) After the time of entering WINDOWS 95/98, 3D positional audio (listening Debate bit) has become a hot topic, there have been Qsound Q3D, SenSaura, Au
real innovation and put forward their own 3D algorithm, the development of the EAX Environmental Audio, with the position before the sound is very different. However, due to differences in size, and game manufacturers are not very much concerned about this one feature, coupled with its consumers know little about, 3D CANON np-e3 battery positional audio, and not really accepted by the market.

5, multi-channel output

3D positional audio is just the beginning in order to simulate the two-channel 3D sound, and later on the development of the four channels, so that more realistic effects, but so far all this is only used in the above GAME, the only real “Positioning “effect, in general, or audio MP3 player, the only copy in front of the rear of the sound source, no orientation at all, then some companies excessively advertised four-channel output, in fact, listening to MP3, the user they used to do four-channel output sound separately is the same meaning.

6, sound card compatibility problems

Although the CANON nb-5l battery performance is very good PCI sound card, but there are many problems, such as the user MVP3 and ALI5 chipset motherboard, some motherboards are not compatible sound card may be. Also the integrated motherboard sound chip, many are low-end products, higher quality requirements of the users do not recommend purchase of such board, to avoid future replacement of the sound card a waste of resources. For the high-end sound card, never matching cheap speakers, sound card, no matter how otherwise can not be demonstrated.

7, SPDIF digital audio interface

The sound as a digital signal transmission to minimize distortion. SPDIF for connecting the output of the digital recording device specifically, but the SPDIF input interface receives the appropriate drive, you can get analog audio inputs than the use of much better sound quality.

8, AC-3 decoding

3D positional audio was originally thought that this way comes to an end, at this time, with the rise of DVD, plus WINDVD / POWERDVD DVD playback software such as the maturity and support.

This is still SONY NP-FM50 battery software decoding method, and so far, really make a 5.1 output only ForteMefia this software company, said other companies are also developing in this direction. For other companies, innovation is basically not for its product launch this software decoding scheme, will continue to SB Live! Digital output coupled with its full range of AC-Decoder +5. 1 channel decoding is still C / P value of the highest way, but the products can be found in the market are not many.

9, other issues

There are some common questions about the PCI sound card, first of all, some 32-bit PCI sound card nominal / 64 does not refer to its audio samples, the median is the 32/64 bit, but to their maximum polyphony is 32 / 64, which is broadcast in the use of MIDI wavetable synthesizer and other sound files, the maximum number is 32/64 were also pronounced, this effect when playing MIDI, sound samples to the concrete is still 16-bit, do not forget The CD is now making 16-bit sampling, and now professional digital voice recorder was only 20 bits of precision, not to mention the amateur computer sound card. There is also the compatibility of PCI sound card, perhaps it has already bought a lot of friends PCI sound card problem most frequently encountered is its compatibility, in particular, its DOS, particularly the problems. Because olympus li-40b battery PCI sound card sound synthesis sound card the same way as in the past are very different, not compatible with DOS, the original IRQ, DMA interrupt. Therefore, most DOS games do not recognize PCI sound card, there would be no sound. But these problems do not exist under Win95 the. As for how to resolve the compatibility issue under DOS has no good solution yet, if you buy sound card primarily for use in DOS, that ISA sound card or buy it.

I write to you, I believe we will be on a basic understanding of sound, in fact, in the purchase card Shihai should note the following questions:
1, the full analysis of their actual needs, cut will not see a good sound card to buy at the same time, Do not buy blind pursuit of high-end sound card comparisons psychology.
2, if you usually use the sound card is only used in literary work, or play some DOS games, take a look at DVD, then not take too much to buy high-end sound card, as long as 100 yuan to buy the sound card already meet your needs the. If you are more advanced now play computer games, then take 300 or so sound card is already very good. If you are a super music enthusiast, then you should buy high-end sound card a little.
3, sound card during the purchase, be sure to see if a decent sound card manual.
4, able to do so, you buy those big battery shop manufacturers introduced the sound card, because of their quality and security, and sales and service is more perfect.

Sound Card Base Knowledge

Comments Off

Since 1998, sound card interface has been shifted from the ISA PCI. Now in addition to some older machines are configured ISA sound card other than the market as early as Yishi rare sight of. PCI sound card with its fast transfer rates, low CPU utilization and better 3D sound, sony np-bg1 battery MIDI outstanding performance and won the market.

First, the basic structure of the sound card

1. Audio processing chips: the main wave to complete the sampling and synthesis WAVE, MIDI music synthesis, while mixing, effects also in its internal implementation, is the most basic parts of the sound card.
2. Game / MIDI port: for connecting joysticks, handles, steering wheel game controller outside, but can also be used to connect the MIDI keyboard and the keyboard.
3. Linear output jacks (LINE OUT): used to dealing with a good sound card input to the active speaker, headphones and amplifiers.
4. Microphone input jack (MICIN): used to connect microphones, mainly used in speech recognition, entertainment and recording and so on.
5. Linear input jacks (LINE IN): used to Walkman and other Dell inspiron 1520 Battery external devices or TV sound signals into a computer.
6. Interface, automatic telephone answering device (TAD, Telephone Answering Device): with MODEM card and software will enable computers with automatic telephone answering function.
7. Analog CD audio input (CD-IN): to drive the analog audio signal from the access.
8. Auxiliary audio input (AUX-IN): used to MPEG encoder / decoder card, TV card, DVD Decompression Card sound signal input devices such as sound cards, making the sound signals of various devices through the sound card to the speakers.
9. Digital CD audio input (CD-SPDIF): role is to receive digital audio signals from the drive to ensure that minimize sound distortion.
10. Digital daughter card expansion pin (SPDIF-EXT): used for supporting daughter card connections, digital CANON nb-2lh battery signal input and output. Can make the sound card and a dedicated digital recording equipment is connected (such as: DAT, MD), and can output AC-3 signals.

With the improvement of the overall performance of computers, people continue to pursue a more perfect music and sound effects, and thus demand more and more the sound card, sound card today, a wide range of terminology has long been the “siege”, then we to see what they really mean is it!

Second, the sound of the basic terminology

Sample median: the value of the KODAK klic-7001 battery samples or sampling. It is used to measure the sound wave changes in a parameter, that is, the resolution of the sound card. The greater its value, the higher the resolution, the ability to sound stronger. Sound the human ear due to limited precision, multi-media computer with 16-bit sound card.

Sampling frequency: the sampling frequency, means the number of times per second to obtain voice samples. The higher the sampling frequency, the sound quality is better, the more reduction of sound true, but it accounts for more resources. Because the resolution of the human ear is limited, too high a frequency can not tell the difference. In the 16-bit sound card in 22KHz, 44KHz, such as several levels, including, 22KHz audio quality equivalent to an ordinary FM radio, 44KHz is equivalent to CD sound quality, and now commonly used sampling frequency of no more than 48KHz.

MIDI: Musical Instrument Digital CASIO np-20 battery Interface is short, which means Musical Instrument Digital Interface. It is an electronic musical instrument as well as between electronic instruments and computer communication between the unity agreement. Many popular games, entertainment software and have a lot to MID, RMI extension of MIDI format music files. MIDI file is a descriptive “music language”, it will play the music information to be described in bytes. For example, at a time, using an instrument, what the notes start to the end of what tone, what is to be accompanied by, and so, That MIDI file itself does not contain waveform data, MIDI files are very small. MIDI music to form the computer must be synthesized. Early ISA sound card is commonly used in FM synthesis, the “frequency modulation.” It uses the principles of sound oscillations were synthesized on the MIDI processing, due to the limitations of the technology itself, the effect is hardly satisfactory. And now is used mostly wavetable synthesis sound card, and it will first issue a variety of real musical instruments can all sounds (including all range, tone) were sampled, stored as a wave table file. During playback, MIDI file according to the information recorded music to give directions to the wave form, from the “table” in the voices one by one to find the corresponding information through the synthesis, processing it later playback. Because it uses a real instrument samples, so the effect of natural is better than FM. General Dell XPS M1530 battery wave form of the instrument sound information to 44.1KHz, 16Bit accuracy of recording, in order to achieve the most realistic playback. In theory, the wave table synthesis capacity of the larger the better. Placement based on the sample files and the special microprocessor or CPU to handle the different wavetable synthesis and is often divided into soft and hard wave form wave form.

MP3 WAV: sound files is by using a specialized algorithm for the ratio of 1 to 10, compressed into small files for storage. The WAV is a sound recording itself, so it accounts for a large hard disk space. For example: 16-bit 44.1KHz stereo sound, a minute to take about 10MB of cheap sony batteries capacity, and far more backward than MIDI.
