Common faults and solutions of integrated sound card

With the gradual improvement of the integration of the motherboard, the integrated sound card has become the current trend of computer development, and with the integrated sound card chip technology to improve, take the independent sound card and the trend of the generation.

According to popular classification, the AC ' 97 sound card is divided into two kinds of hard sound card and soft sound card, of which AC ' 97 hard sound card, the first most independent sound card is hard sound card, and the sound card integrated on the motherboard also has a hard sound card: these sound cards in addition to the audio codec chip, but also on the motherboard integrated digital Control chip, that is, the chip and auxiliary circuits are integrated into the motherboard. These sound card ICS provide a separate digital audio processing unit and ADC-to-DAC conversion system that ultimately outputs analog sound signals. This hard sound card and ordinary independent sound card is not very different, more like a fully integrated on the motherboard of the independent sound card, and due to the increase in integration, the CPU load is reduced, the sound quality has improved, but the corresponding cost has also increased, is now rarely used by motherboard manufacturers.

The AC ' 97 soft sound card only integrates the audio Codec on the motherboard, while the digital control is completely replaced by the CPU, saving a lot of cost. According to the AC ' 97 standard, pin-compatible between different audio Codec97 chips, in principle, can be replaced with each other. That is, the AC ' 97 soft sound card is only a codec chip based on the AC ' 97 standard, does not contain the digital audio processing unit, so the computer when playing audio information, in addition to D/A and A/D conversion of all processing work to be done to the CPU. It can be said that the AC ' 97 soft sound card only simplifies the hardware, and the design is still the implementation of the AC ' 97 standard sound card. There are also some consumers think: soft sound card is no digital control chip, but the use of software simulation, so there are two problems: first of all, its CPU occupancy rate is certainly higher, prone to burst sound, and the next sound quality can not be compared with ordinary independent sound card.

In fact, with the increasing CPU frequency, audio data processing volume has not increased much, so-called CPU occupancy problem has long been neglected. As for the sound quality, although it is difficult to compare with the high-end independent sound card, but with the Soundmax 3.0 drive continuous upgrading and improvement, Enables the AC ' 97 soft sound card to have hardware-level data processing conversion capability and a professional sound playback capability of up to 94dB Snr, increased sensaura for 3D positioning sound, SONDIUS-XG midi soft wave table compatible with XG, and the latest sound algorithm SPX, which will AC ' The 97 soft sound card has been upgraded to an unprecedented height, radically changing the image of consumers in the minds of poor quality.

Sound card in the use of the process often encounter some strange problems, including hardware problems, but also contains numerous software failures, the following will select a number of representative issues, through the understanding of these problems and solutions, consumers can make appropriate treatment according to the situation, timely solution to practical problems.

First, the sound card is silent

If the sound card installation process is normal, the device can be recognized, generally speaking, the likelihood of hardware failure is very small.

1. Whether the speaker or headset is connected correctly.

2. Whether the speaker or headset is in good condition.

3. There is no damage to the audio cable.

Whether the various sound channels in the 4.Windows volume control are blocked.

If all of the above 4 are normal and still have no sound, then we can try to replace the newer version of the driver and remember to install the latest patch for the motherboard or sound card.

Second, play MIDI silent

Some sound cards are very normal when playing MP3, playing games, but you can't play midi files. From the principle point of view, the sound card itself is not a problem, should belong to the setup problem.

can go to the control Panel → multimedia → audio →midi music playback, select the appropriate playback device. Of course it may be in

The MIDI channel in the Windows volume Control is set to silent mode, and the mute check is removed.

Third, play CD silent

If the playback MP3 has a sound, you should be able to troubleshoot the sound card. The biggest possibility is that you are not connected to the CD audio cable.

The CD can be decoded directly on a normal CD-ROM and connected via the 4-wire and sound card supplied with the CD-ROM. The end of the line is connected to the analog audio output on the CD-ROM, and the other end is connected to the CD in the integrated sound card, cd-in generally can be found around the integrated sound card chip, it is important to note that the audio line has the size of the head, you must use the appropriate audio line with it.

Four, unable to play WAV audio files

You cannot play WAV audio files because there is more than one audio device under control Panel → multimedia → devices, disable one.

V. Noise during playback

Snr is generally the culprit of noise, integrated sound card is especially affected by background noise, but with the sound card chip signal-to-noise ratio, most of the integrated sound card signal to noise ratio of more than 75dB, some high-end products, even up to 95dB signal-to-noise, the problem of noise is getting smaller. In addition to the signal-to-noise ratio, clutter electromagnetic interference is the only reason for the noise to occur. Because some integrated sound card using a cheap power amplifier unit, workmanship and materials are more unsightly, SNR is far lower than the standard of high-grade motherboards, natural noise can not be controlled.

As the speaker out uses the amplifier unit on the sound card to amplify the signal, although the output signal is "big and fierce", but the SNR is very low. And line out is bypassing the sound card on the power amplifier unit, the signal directly to the transmission of the circuit to the speaker, if there is background noise may wish to try this method, I believe it will improve a lot. But if you are using inferior speakers, I believe the improvement will not be very big.

Six, sound card when running a large program with a pop-up sound

Because the integrated soft sound card digital audio processing relies on the CPU, this problem can occur if the computer is configured too low.

In the Control Panel, select system → Device Manager, select the disk drive, locate the hard drive's parameter entry, double-click the parameter entry, and in the popup interface, remove the check mark in front of the DMA option of the hard drive. However, when the DMA data interface is turned off, the performance of the system is reduced, or the latest motherboard patches and sound card patches are installed, and the latest drivers can be replaced with some results.

Seven, after installing the new Direct X, the sound card does not sound

Some sound cards have drivers that are incompatible with the new version of Direct X, causing the sound card to not sound at the new Direct X.

If your sound card doesn't sound after you install a new version of Direct X, you'll need to replace the old one with a new driver for your sound card or a "Direct X free" tool to uninstall Direct X.

Eight, Direct x diagnostic display does not support hardware buffering, sound card does not sound

The software buffer is too small to cause audible noise.

Open Control Panel, multimedia properties → device → media control device → waveform audio device, there is a setup option to change the default 4-second software buffer capacity to the maximum of 9 seconds.

After overclocking, the sound card will not be used properly

Due to overclocking, some integrated sound cards work in abnormal frequency, there will be a burst sound, not audible and so on.

I recommend not overclocking, so that the normal work of the sound card is no problem. If you must use overclocking, as far as possible to work at the standard frequency, so that the integrated sound card can also work at normal frequencies, generally can also ensure normal use.

Ten, the sound card cannot record

Most of the integrated sound cards are full-duplex sound cards, while the recording portion of the individual damage probability is very small.

First check that the jack is "mic in", then double-click on the "Small horn" icon and select "Properties → recording" On the menu to see if the settings are correct. Next, in "control Panel → multimedia → device", adjust "mixer device" and "line input device", set them to "use" status. Then to the "control Panel → multimedia → audio → recording preferred Device", click on the Small Microphone icon to enter the "recording control", where you can preset the required audio channels, and then you can use the recording function. If this little thing turns gray, try removing the card to reload.

Of course there are special cases: because the integrated sound card generally does not have a power amplifier chip, can not promote high-end recording equipment, so that can not be recorded, in this case, the replacement of high-grade sound card, or replace the higher-grade motherboard. The author's apple mic can only be used on ASUS motherboard or SB live sound card. Of course, if you do not care about the effect of mic, you can replace a low-grade mic to solve the problem.

The integrated sound card is similar to the fast-forward effect when playing any audio file

As the sound card has been audible, I believe the problem may be set and drive.

If your computer is overclocking, you should first reduce the frequency and then turn off the speed of your sound card, and if that doesn't work, you should look for patches and new drivers for your motherboard and sound card.

12. Cannot use four channels properly

Some integrated sound cards are able to sound properly and cannot use the four-channel mode, believing that the problem is set.

Many sound cards are through the software to simulate the four-channel, simply the sound of the front speaker to copy to the rear speaker, so that when playing MP3 and or listen to the CD is a four-channel, and in the 3D play or play DVD when there is no way to say these sound cards, is not the true four-channel.

13, when running the network chat program, the sound is intermittent

In fact, this problem does not close the sound card thing, because the network traffic restrictions, network bandwidth can not smoothly transfer sound signals.

As far as possible in the network chat do not open large programs, do not have to download such large traffic network operation, if you can replace the network access mode, increase the bandwidth, will be a one-time solution.

14. After replacing the sound card multiple times, the Windows prompt does not discover the hardware driver when the integrated sound card is reused

This type of failure typically occurs when the driver is loaded for the first time, or in Config.sys, automatic batch file Autoexec.bat, Dosstart. A sound card driver is already running in the bat file.

You can delete a driver file that is running inside, and of course, you can remove the three files mentioned above to resolve the failure. If there are no files in the above three files, and the driver is not loaded, you need to modify the registry, click on the "Start" menu--"Run", enter "regedit" in the dialog box to return to the sound card related to the registry key Delete (such as the sound card model is ALc650, click the registry key "edit "--" find ", enter ALS300, then delete the found bytes, then press F3 to continue looking for the next, then delete the found option.

XV, BIOS settings

The onboard sound card is shielded from user misoperation that is unfamiliar to the BIOS.

Enter BIOS, select I/O Device configuration→onboard AC97 Audio Controller, select Enanle or Auto. This process is passed on the author's Asus Motherboard, on other motherboards also basically similar, if it is award BIOS, enter the BIOS "Intergratedperipherals", and then select "AC97 Audio" Change "Auto" for "Disable" Save it.

16. After installing the network card or other equipment, the sound card no longer sounds

This problem is more representative, mostly due to compatibility issues and disruptive conflicts.

The problem of driver compatibility is better solved, the user can update the driver of each product. And breaking the conflict is more troublesome. First go to the control Panel → system → Device Manager, query the respective IRQ interrupt, and can directly set the IRQ manually, eliminate the conflict. If the Device Manager is unable to eliminate the conflict, the best way is to go back to the BIOS, close some unwanted devices, and empty out the extra IRQ interrupts. You can also switch the network card or other device to a slot, which will also change the respective IRQ interrupts in order to eliminate the conflict. After swapping the slots, you should enter "reset Configutionration Data" into the "PNP/PCI" entry in the BIOS to enable, empty the PCI device table, and reassign the IRQ interrupts.
