Computer Sound Breakdown Problem Summary

What is the reason why the computer is hoarse? Usually the sound card is driving the problem. Download a "Driver Wizard" First, then update the sound card driver, it is OK. It is recommended that you use the following methods for troubleshooting:

In the daily use of computers, we sometimes encounter computer sound is not normal, such as:

1, the computer sound big;

2, the computer sound is small;

3, computer sound distortion;

4, computer voice hoarse;

5, the computer sound suddenly gone;

6, computer sound is very card and so on.

The following small series for you to solve the problem of computer sound failure.

Most of the friends of the computer generally used to listen to music on the internet to watch movies, are brought to entertain. So sound becomes an integral part of it, but many of my friends ' computer sounds often have problems like this or that. Most are due to improper operation caused by, of course, a few cases also include hardware problems, today with you detailed analysis of the computer does not sound fault judgment method, as well as the resolution steps.

The cause of hoarseness of Computer voice:

Hardware failure: Check the audio device for damage, we can take our own device to another computer to see if there is still this problem. If there are problems later, refer to this article for a computer without sound hardware problem solution.

Software problems: Many friends have encountered such problems, in the use of anti-virus software after the computer does not sound, in fact, this is due to the virus infected audio files, antivirus software can not remove the virus, so only the infected files deleted together.

Drive problem: According to my years of maintenance cases, most of the reasons for the lack of sound computer is due to this cause. So this is the focus of our discussion. First of all, how to determine that our computer does not sound the problem is caused by the drive problem? First open the computer Device Manager, either "Control Panel/System Properties/Hardware/Device Manager", or right-click on My Computer to select Properties and then tap hardware to enter the Device Manager list. Next to see if there is a yellow question mark or exclamation mark, if the yellow exclamation point is not loaded driver, if the exclamation point is due to the sound card mismatch caused by the exclamation point is the right button to select Uninstall. If it is a question mark, you need to reinstall the driver, for the driver completely do not understand the friend, you can download "Drive Life" or "Drive Wizard", after the installation is opened will automatically prompt you to install the driver, click Update it will automatically install. For experienced friends, it is recommended that you go to the official website to download the latest sound card drivers, the driver will be better than the effect of automatic download.

If it is not connected to the network of friends, or with the Driver wizard, driving life can not be updated friends, it is recommended to download a driver package, this driver package contains most of the computer's sound card, video card, network card and other drivers. You can go to "Tian Nuo time and space" download, pay attention to see your system, and then download the corresponding driver package. My USB flash drive inside put a copy of Windows XP and Windows7 driver, so that others let the computer repair, encountered about the lack of driver problems, directly take out can be used. It should be declared that this method only works when the sound card has a yellow question mark, because it does not automatically update your driver, it will automatically skip if it has already been installed, so you can right-click to delete and then open the driver package installation. This kind of computer does not have the sound problem, must remember to start from the small first, for example to see the sound or the headset sound is adjusted to be the smallest.

One, the computer sound Big solution method:

(a), desktop computer sound large

Computer mainframe fan use for a long time, too much dust on the fan, or the fan is short of oil, resulting in fan speed faster, the more noise, the solution is as follows:

1, regularly clean up the dust on the computer fan, wipe the fan clean.

2, give the fan ball bearings there oil, not too much oil. In general, good fan ball bearings have very little noise.

There are typically three fans in the chassis: CPU fan, video card fan (optional), power supply fan. The best solution is to replace the new fan. If you are frugal and don't want to change, you can also listen to which fan is making the sound and deal with which.

The fan will rotate at a high speed when the computer is fresh, and if the fan is short of oil, the sound will be much smaller after entering the Windows system. In the elimination of the fan due to the vibration caused by not tightening and the sound of an object hit the fan blade, the most likely is the lack of oil caused by, refueling method is very simple, the first to remove the fan from the seat, and then look at the back of the fan (a few in front) is not glued to a circular plastic sheet, is generally not dry will see the fan motor bearings, when the oil here is too dry fan will ring, when looking for some sewing machine oil or car oil, do not too sticky, the idea drops one or two drops of oil into the bearing cavity, see oil-immersed bearings can be (fan must maintain level), pay attention not to let the oil diffuse to the fan surface, otherwise it will affect the adhesive , at this point around the oil hole to glue the plastic sheet glued back and air-dried, dry after the fan back, then turn on, the sound is much smaller?

(b), notebook computer sound large

1, the fan dust too much.

Workaround: Disassemble the laptop, clean the fan regularly and wipe the fan clean.

A laptop fan, typically on a heatsink. Notebook calorific value, than desktop computer, much smaller.

2, the fan has quality problems: Old fan, or fan page problems.

The laptop does not heat well, and the fan spins faster, resulting in a very loud sound. In this case, the new fan must be replaced.

Second, the computer sound Small solution method:

Sound card and speaker common failure mainly silent, small voice, only one speaker sound, voice modulation, there is a burst sound, crackling sound, etc., causing the main reasons for this failure are silent, the volume is too small, sound card driver problems, speaker damage, sound card module damage, BIOS setup problems, sound card and other equipment conflicts, bad sound card contact, Sound card is damaged and so on.

Computer silent troubleshooting methods are as follows:

(1) First check the taskbar to the right of the "small horn". If there is, then the sound card is normal, the cause of the failure may be the system sound is too small, or set the mute, or the speaker failure caused. You can continue to check for sound output through the headset, and if so, it is a malfunction of the speaker.

(2) If there is no "trumpet" on the right side of the taskbar, click the Control Panel/sound and Audio Devices command, open the sound and Audio Device Properties dialog box, click the Sound tab in the dialog box, and then click one of the program events (such as an error in the program) in the Program events column, and then select a type of sound, Then see if the Preview button on the right is black. If it is black, the sound card is normal and the fault may be because the system volume is too small or muted, or the speaker is faulty.

(3) If the preview button in the Sound tab is dimmed, then click Control Panel/System Properties/Hardware/Device Manager to see if there is a yellow "?" in the Device Manager window. 's Options.

(4) If there is a yellow "?", see if the option is a sound card device option (there are often keywords such as "audio" or "sound" in the device options). If the option is for a sound card device, the sound card driver is not installed and the sound card driver is reinstalled to resolve the silent problem.

(5) If there is a yellow "?" The option does not refer to a sound card device, or no yellow "?" option, then look at the sound, video and Game Controllers tab under the Yellow "!" 's Options.

(6) If there is a yellow "!", it may be a sound card driver mismatch, or the sound card is caused by aging. Then delete with "!" option to reinstall the sound card driver.

(7) If there is no sound card option in the Device Manager window, and the sound card is an integrated sound card, then restart your computer to enter the BIOS program. Then check that the peripheral device option is set to "Disabled" in the BIOS, and if so, change it to "Enable". If this setting i "Enable", it may be the motherboard sound card circuit damage, repair the sound card circuit.

(8) If the sound card is not an integrated sound card, then open the chassis and check if the sound card is installed. If not installed, after re-installation, the power test can be, if the sound card has been installed, and then remove the sound card, and then clean the motherboard sound card slot and the sound card above the dust (especially to check whether the gold finger is bad, etc.), clean, and then reinstall, General fault can be ruled out.

(9) If the sound card is not normal, then there is a problem with the sound card, replace the method to check whether the sound card is damaged or incompatible with the motherboard. If the sound card is damaged or incompatible with the motherboard, replace the sound card.

Third, the computer sound is not normal how to do?

The computer sound is not normal malfunction, can be handled by the following ways

(a), check whether the latest sound card drivers are installed.

(b), the quality of speakers may be problematic. Lower-quality speakers tend to be more distorted than higher-quality loudspeakers in bass. If the speaker is of low quality, the playback effect can only be improved by a hardware upgrade.

(iii), sound distortion may be due to the volume sent to the speaker is too high, beyond the processing range of the speaker, you should try to reduce the volume sent to the speaker.

(d), check that the "Use single mode DMA" setting is correct. Check that the "Use single mode DMA" setting is turned on:

1. Click Start, point to Settings, click Control Panel, and then double-click System.

2. On the Device Manager tab, double-click Sound, Video, and game controllers, and then double-click the sound card. If you do not know the name of your sound card, consult your sound card documentation.

3. Click Properties, and then click the Settings tab. Click Advanced Settings, and then click to select the Use single mode DMA check box. If the Advanced Settings button does not appear on the Settings tab, the sound card does not support this feature. Click OK consecutively, return to Control Panel, and then close Control Panel.

(v) A hardware device conflict may exist on the computer. Check that the Device Manager tab contains the device and there is no conflict. Click Start, point to Settings, click Control Panel, and then double-click System. On the Device Manager tab, check that the device is present and that there are no yellow circles with an exclamation point next to the device. If a yellow circle with an exclamation point appears next to the device, the device may be using the same settings as other devices on your computer. If you find a yellow circle with an exclamation point: Double-click the device, and then click the Resources tab. In the conflicting devices list, look for resource conflicts. If there is a resource conflict, reconfigure one of the devices to use different resources to eliminate the conflict.

Iv. solving the problem of computer sound distortion

1. Check to see if the latest sound card driver is installed.

2. There may be a problem with the speaker quality. Lower-quality speakers tend to be more distorted than higher-quality loudspeakers in bass. If the speaker is of low quality, the playback effect can only be improved by a hardware upgrade.

3. Sound distortion may be caused by too high a volume to be sent to the speaker, beyond the speaker's processing range, and you should try to reduce the volume sent to the speaker.

4. There may be a hardware device conflict on the computer. Check that the Device Manager tab contains the device and there is no conflict. Click Start, point to Settings, click Control Panel, and then double-click System. On the Device Manager tab, check that the device is present and that there are no yellow circles with an exclamation point next to the device. If a yellow circle with an exclamation point appears next to the device, the device may be using the same settings as other devices on your computer. If you find a yellow circle with an exclamation point: Double-click the device, and then click the Resources tab. In the conflicting devices list, look for resource conflicts. If there is a resource conflict, reconfigure one of the devices to use different resources to eliminate the conflict. For specific operational information, please refer to the device documentation or contact the manufacturer.

5. Check that the "Use single mode DMA" setting is correct. Check that the Use single mode DMA setting is turned on: Click Start, point to Settings, click Control Panel, and then double-click System. On the Device Manager tab, double-click Sound, Video, and game controllers, and then double-click the sound card. If you do not know the name of your sound card, consult your sound card documentation.

Five, the computer does not sound hardware problem solution

Today, I'd like to introduce you to the solution of hardware problems that cause the computer to have no sound. As the title shows, the first thing to make sure that your computer doesn't have a sound problem is that it doesn't have anything to do with the system.

First check the host with the headset or audio connection cable is not a problem, such as loosening, disconnection and so on. Second, to determine whether the power supply has not been opened, headphones or audio volume switch is not open to the smallest. Next you need to open the box to check the sound card and the slot on the motherboard for good contact. Generally, after we have dialed the sound card, you can clean it with an eraser and plug it in again.

(a), after the installation of hardware equipment, the computer does not sound how to do

This is the case when a new network card is installed, or other hardware devices, the computer will not sound.

There are generally only three solutions to this problem, and one is to re-update the conflicting drivers. The second approach is to change the interrupts in the BIOS to eliminate the conflict. The third option is to replace the hardware.

Most of this happens because of the disruption and compatibility between hardware, the compatibility between hardware issues, generally as long as it is not particularly new equipment, manufacturers will give the latest driver to solve such problems. In this case, we just need to follow the first approach. And it might be a little more cumbersome to break the conflict. First, go to Device Manager to see the IRQ interrupt that just replaced the hardware, and then manually set up the IRQ inside to eliminate the problem of interrupt conflict. If it does not solve the problem, then you need to enter the BIOS, shut down the computer can not be used on the device, so that there are many IRQ interrupts, of course, such as memory, card, such as hardware more than one slot, the other slot can sometimes solve the problem, because it will change the hardware above the various IRQ interrupts, This time we can enter the BIOS, in the PNP/PCI selected reset configutionration data re-open, which is set to enable, then the computer will empty the PCI device table, reassign IRQ interrupts, The probability of a recurrence of this conflict is very small. The last thing that happens is that only the hardware is replaced, which is basically because the device is very new.

There is still less problem with the computer having no sound after installing the hardware device, but there are still some. The computer I have worked on has encountered more than 10 cases, so be prepared.

(b), the BIOS error setting causes the computer to have no sound

This happens because some novice just started to learn BIOS settings, accidentally set the wrong BIOS inside the option caused by. This situation is more troublesome for newbies, because look at the BIOS itself does not know just where to do the setup. As a result of the changes made in the BIOS, the computer will still have no sound even if the system is re-made. There are only three ways to solve this situation.

1. Find the BIOS sound card option and change it back. A common BIOS modification method is described below. First enter the BIOS, select the I/O Device configuration, Onboard AC97 Audio Controller, and change it to Enanle or auto. My computer is HP, the BIOS of other computers may be different from mine. But we can find the appropriate words to enter the settings.

2. Restore the BIOS to default. Enter the BIOS, then select the load Setup Defaults BIOS or the word like restore Setup Defaults. I personally recommend this method, for those who do not know how to set up a friend, this method is the simplest and most effective.

3, the BIOS discharge, this method needs to disassemble the boot box. Remove the BIOS battery. The positive and negative pole butt discharge can be. I won't say much about this method.

(c), the computer suddenly no sound what to do

Some friends have a strange problem with the computer without sound, with the use of a sudden no sound. According to reason to say that they do not have any changes, the system should be no problem, there was a sound before, said obvious card also no problem, hardware equipment, the probability of problems is very small, this problem is often plagued by many friends. Today, we will explain the computer with the use of a sudden no sound of several solutions.

Such a computer problem, the first to recall that their computer suddenly did not sound when there is no software, many software conflicts will also cause the computer no sound, this failure, some because the old sound card does not support multi-audio streaming, and does not support ACPI interrupt sharing features. If that's the reason, you can update the software or see if your sound card is up to date. Of course, if there is no solution, you can also send your feedback to the manufacturer.

Second, it is recommended to reinstall the sound card driver, the most standard solution is to boot into safe mode, uninstall the sound card (this time it will not automatically reinstall). Next normal boot into the system, according to the prompts to reinstall the sound card driver. Go to the control Panel to see whether the various settings are correct, if all is correct and still no sound, this time you can consider whether the sound card is bad, if it is integrated, may also need to change the entire motherboard. Of course, before this situation, it is best to confirm that your installed sound card driver is correct, the most secure is to go to the official website to download.

(iv), after updating the sound card driver or no sound how to do

As we all know, there is no sound card driver, the computer is certainly no voice, now the ghost system is generally installed after the automatic installation of all the drivers. But often many friends just installed after the system found that the sound card is not missing, but still no sound, this time we can try to go to their own computer system of the official website to download a sound card driver.

If the sound card is installed, our computer still has no sound, and the sound card does not have a problem, this time we can check to see if the sound card driver is disabled reasons. Because the sound card is temporarily disabled when some software is installed, the software will automatically re-turn on the sound card driver after the installation is complete. If there are unexpected issues such as installation errors and so on. Then the results can be imagined. About the sound card is disabled, we can try to reopen the following method.

First go to Device Manager, expand the "sound, video and game controller" option, find the sound card entry, right-click (if the sound card driver is disabled, its small horn icon will have a fork in front of it.) ), another possibility is that the sound is turned off in the sound properties. The solution is to first go to the Control Panel, open the "sound and Audio Devices" option, in the pop-up Properties window, select "Volume" and then adjust the sound to the appropriate location. If you don't have a "small horn" icon in the lower right corner of your desktop, you can also check the box in front of "put the volume adjustment icon in the taskbar." After exiting you will find that the computer has no sound problem has been resolved.

(v), the virus causes the computer to have no sound solution

Many friends have encountered such problems, in the use of anti-virus software after the computer does not sound, in fact, this is due to the virus infected audio files, antivirus software can not remove the virus, so only the infected files deleted together.

This situation, in fact, is also very good solution. General antivirus software after the removal of virus files are not directly deleted, it will be saved in the backup directory, just in case the accidental deletion of files caused a variety of system problems, we can find in the anti-virus record, restore it. But this can be described as a palliative, although the sound is back, but the virus has come back, in this case, we could write down the deleted file name, and then go to another good computer copy a new, paste to the same location. Of course you can also extract from the Ghost System package.

Another solution to this problem is to reinstall the driver after it has been removed. This approach can be resolved if the virus is infected with an audio driver file. But if it is the main audio program, then this method is powerless.

(vi), the lower right corner of the computer does not have a small horn icon what to do

Many friends in the use of the computer may have encountered the computer in the lower right corner without a small horn icon problem, encountered this problem is very simple solution, before the solution to the first to determine what is the problem. Excluding the hardware problems of audio devices, generally leading to the lower right corner of the computer there is no small horn icon for two reasons, the first sound card problems, there are improper settings caused by such problems. For some novice friends, the distinction between the two conditions is also very simple, if the reason for the sound card, then the lower right corner of the icon will not only, and will be accompanied by computer no sound symptoms. If your computer still has sound, then it is your improper settings caused, it is easy to encounter this reason, just need to go into the control Panel to set up a bit.

In the first case, you can see if your sound card is installed properly in Device Manager (no successful installation, or a yellow question mark if there is a problem), you can download a driver life, or a Driver wizard update (the software will automatically prompt you to update which). If this is the second case, you need to go to the control Panel. After entering the rear panel, click on the sound and audio device and put the volume icon in the taskbar. If there is no effect, it may be caused by the loss of system files Sndvol32, this time you can go to another computer to copy a good, you can also extract a copy from the System Ghost package to c:windowssystem32 under also can.
