What should I do if my computer sounds hoarse? Usually when we use computers, we often encounter problems with computer sound, such as hoarseness. What's going on? Is there any way to solve it?

Next, let's take a look at how to solve the problem of abnormal computer sound.

In the daily use of computers, we sometimes encounter abnormal computer sounds, such as:

1. The computer sound is loud;

2. The computer sound is low;

3. The computer sound is distorted;

4. The computer sound is hoarse;

5. The computer sound suddenly disappears;

6. The computer sound is very stuck.

Computer sound problems are mostly caused by incorrect operation. Of course, in a few cases, hardware problems are also included. Today, I will give you a detailed analysis of the fault diagnosis method of computer no sound. and resolution steps.

Hardware failure: Check whether the audio device is damaged. We can replace our own device with another computer to see if the problem still exists. If you still have problems after that, you can refer to this article about solutions to computer no sound hardware problems.

Software problem: Many friends have encountered such a problem. After using anti-virus software to check for viruses, the computer has no sound. In fact, this is due to the virus infecting the audio file, and the anti-virus software cannot remove the virus. , so only the infected files are deleted together.

Driver problems: According to my many years of maintenance cases, most of the reasons why computers have no sound are due to this reason. So this item is the focus of our discussion. First of all, how to determine whether the problem of no sound in our computer is caused by a driver problem? First, open the computer device manager. The specific method is "Control Panel/System Properties/Hardware/Device Manager". You can also right-click My Computer and select Properties and then click Hardware to enter the Device Manager list. Next, check whether there is a yellow question mark or exclamation mark. If it is a yellow exclamation mark, it means that the driver is not installed. If it is an exclamation mark, it means that the sound card does not match. If it is an exclamation mark, right-click and select Uninstall. If it's a question mark, you need to reinstall the driver. For those who don't know anything about drivers, you can download "Driver Life" or "Driver Wizard". After the installation is completed and you open it, you will be automatically prompted to install the driver. Click Update and it will be installed automatically. . For experienced friends, it is recommended that you go to the official website to download the latest sound card driver. Such driver will be better than the automatic download.

If you are a friend who cannot connect to the Internet, or useFor those who cannot update Driver Wizard or Driver Life, it is recommended to download a driver package. This driver package contains drivers for most computer sound cards, graphics cards, network cards, etc. You can go to "Tiannuo Space" to download, pay attention to your system, and then download the corresponding driver package. I have a copy of the Windows XP and Windows 7 drivers in my USB flash drive. This way, if someone wants to repair their computer and encounters a problem about missing drivers, they can just take it out and use it. It should be noted that this method can only be used when a yellow question mark appears on the sound card, because it will not automatically update your driver, and will automatically skip the already installed driver. In this case, you can right-click to delete it first, and then Open the driver package installation. If this type of computer has no sound problem, you must remember to start with small checks first, such as checking whether the sound of the speaker or headset is turned to minimum, etc.

1. Solutions to loud computer sounds:

(1) Desktop computers are loud

Use the fan of the computer host After a long time, there is too much dust on the fan, or the fan is short of oil, causing the fan to rotate faster and make more noise. The solution is as follows:

1. Clean the dust on the computer fan regularly and wipe the fan clean. .

2. Add oil to the fan ball bearing, not too much oil. Generally speaking, good fan ball bearings make very little noise.

There are generally three fans in the chassis: CPU fan, graphics card fan (optional), and power supply fan. The best solution is to replace the fan with a new one. If you are more frugal and don’t want to replace it, you can also listen to which fan is making the sound first and then deal with which one.

When the computer is first turned on, the fan will rotate at a high speed. If the fan is short of oil, the sound will be loud. After entering the Windows system, the sound will be much quieter. After ruling out the vibration caused by the fan not being tightened and the noise caused by objects hitting the fan blades, the most likely cause is lack of oil. The refueling method is very simple. First, remove the fan from the seat. Then check to see if there is a round plastic piece stuck to the back of the fan (a few are in the front). It is usually a self-adhesive piece. If you peel it off, you will see the motor bearing of the fan. When the oil here is too dry, the fan will If there is a noise, then find some sewing machine oil or car engine oil. It should not be too sticky. Try to drop a drop or two of oil into the bearing cavity. Just see that the oil has soaked through the bearing (the fan must be kept horizontal). Be careful not to let the oil spread out. to the surface of the fan, otherwise it will affect the adhesion of the plastic piece. At this time, apply some glue around the oil hole to stick the plastic piece back and let it dry. After drying, put the fan back on. Then turn it on again. Is the sound low? Too much?

　(2) The laptop is loud

　1. There is too much dust on the fan.

Solution: Disassemble the laptop, clean the dust on the fan regularly, and wipe the fan clean.

Laptop fan, oneUsually on the radiator. Laptops generate much less heat than desktop computers.

2. The fan has quality problems: the fan is old or there is a problem with the fan page.

Laptop heat dissipation is not good, and the fan will spin faster, causing the sound to be very loud. If this happens, the fan must be replaced with a new one.

2. Solution to low computer sound:

Common faults of sound cards and speakers mainly include silence, low sound, only one speaker has sound, sound changes, popping sounds, crackling sounds, etc. The main causes of this failure are mute, volume Too small, sound card driver problem, damaged speaker, damaged sound card module, BIOS setting problem, conflict between the sound card and other devices, poor sound card contact, damaged sound card, etc.

The troubleshooting method for computer silence is as follows:

(1) First check whether there is a "small speaker" on the right side of the taskbar. If so, the sound card is normal. The cause of the fault may be that the system sound is too low, or mute is set, or the speaker is faulty. You can continue to check whether there is sound output through the headphones. If there is, the speaker is faulty.

　(2) If there is no "Small Speaker" on the right side of the taskbar, then click the "Control Panel/Sound and Audio Devices" command to open the "Sound and Audio Device Properties" dialog box, and open the dialog box Click the "Sound" tab in the box, then click one of the program events (such as a program error) in the "Program Events" column, then select a sound type, and then see if the "Preview" button on the right is black. If it is black, the sound card is normal. The cause of the fault may be that the system volume is too low, or mute is set, or the speaker is faulty.

　(3) If the "Preview" button in the "Sound" tab is gray, then click the "Control Panel/System Properties/Hardware/Device Manager" command to view the "Device Manager" window Is there a yellow "?" option?

(4) If there is a yellow "?", check whether the option is a sound card device option (the sound card device option usually contains keywords such as "Audio" or "Sound"). If it is an option for the sound card device, it means that the sound card driver is not installed. Reinstall the sound card driver and the silent problem will be solved.

(5) If there is a yellow "?" option, it does not refer to the sound card device, or there is no yellow "?"" option, then check whether there is a yellow "!" option under the sound, video and game controller tabs.

(6) If there is a yellow "!", it may be that the sound card driver does not match. Or the sound card is aging. Then delete the "!" option and 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 the computer and enter the BIOS program. Then check whether the peripheral device option in the BIOS is set to "Disabled". If so, change it to "Enable". If this item is set to "Enable", the motherboard sound card circuit may be damaged. , just repair the sound card circuit.

(8) If the sound card is not an integrated sound card, then open the case and check whether the sound card is installed properly. If it is not installed, reinstall it and then turn it on to test; if the sound card is already installed. After installation, remove the sound card, then clean the dust on the motherboard sound card slot and the sound card (especially check whether the gold finger has mold spots, etc.). After cleaning, reinstall it and the general fault can be eliminated.

　(9) If the sound card is still not normal, there is something wrong with the sound card. Use the replacement 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, just replace the sound card.

3. What should I do if the computer sound is abnormal?

If the computer sound is abnormal, you can deal with it through the following methods

(1) Check whether The latest sound card driver is installed.

(2) There may be a problem with the speaker quality. Lower-quality speakers tend to distort the bass more easily than higher-quality speakers. Low, only through hardware upgrade can the playback effect be improved.

(3) The sound distortion may be due to the volume sent to the speaker being too high, which exceeds the processing range of the speaker. At this time, you should try to reduce the volume sent to the speaker. Volume.

(4) Check whether the "Use Single Mode DMA" setting is correct. Check whether 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 thenDouble-click the sound card. If you don't 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, it means that the sound card does not support this feature. Click "OK" continuously to return to "Control Panel", and then close "Control Panel".

(5) There may be hardware device conflicts on the computer. Check that the device is included in the Device Manager tab and there are no conflicts. Click Start, point to Settings, click Control Panel, and then double-click System. On the Device Manager tab, check that the device appears and that there is no yellow circle with an exclamation mark next to it. If a yellow circle with an exclamation point appears next to a device, it might be using the same settings as other devices on your computer. If you see a yellow circle with an exclamation mark: Double-click the device, and then click the Resources tab. Look for resource conflicts in the Conflicting Devices List. If there is a resource conflict, please reconfigure a device(s) to use different resources to eliminate the conflict.

4. Solve the problem of computer sound distortion

1. Check whether the latest sound card driver is installed.

2. There may be something wrong with the quality of the speakers. Lower quality speakers tend to distort bass more easily than higher quality speakers. If the speakers are of low quality, only hardware upgrades can improve the playback effect.

　3. Sound distortion may be caused by the volume sent to the speaker being too high and beyond the processing range of the speaker. In this case, you should try to reduce the volume sent to the speaker.

4. There may be hardware device conflicts on the computer. Check that the device is included in the Device Manager tab and there are no conflicts. Click Start, point to Settings, click Control Panel, and then double-click System. On the Device Manager tab, check that the device appears and that there is no yellow circle with an exclamation mark next to it. If a yellow circle with an exclamation mark appears next to a device, it may be used with other devices on your computer.Use the same settings. If you see a yellow circle with an exclamation mark: Double-click the device, and then click the Resources tab. Look for resource conflicts in the Conflicting Devices List. If there is a resource conflict, please reconfigure a device(s) to use different resources to eliminate the conflict. For specific operating information, consult the device documentation or contact the manufacturer.

5. Check whether 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 don't know the name of your sound card, consult your sound card documentation.

5. Solutions to the hardware problem of no sound on the computer

Today I will introduce to you the solution to the problem of hardware problems causing no sound on the computer. As the title suggests, first make sure that the problem of your computer having no sound has nothing to do with the system.

First check whether there is any problem with the connection cable between the host and the headphones or speakers, such as looseness, disconnection, etc. Secondly, you need to determine whether the power of the speaker is turned on and whether the volume switch of the headphones or audio is turned to the minimum. Secondly, you need to unbox and check whether the sound card is in good contact with the slot on the motherboard. Generally, after we unplug the sound card, we can clean it with an eraser and then plug it back in.

(1) What to do if the computer has no sound after installing hardware equipment?

In this case, the computer has no sound after installing a new network card or other hardware equipment.

There are generally only three solutions to such problems. One is to re-update the conflicting driver. The second method is to change the respective interrupts in the BIOS to eliminate conflicts. The third method is to replace the hardware.

Most of the reasons for this situation are caused by interrupt conflicts and compatibility between hardware. Regarding the compatibility issues between hardware, generally as long as the equipment is not particularly new, the manufacturer will The latest drivers are given to solve this type of problem. In this case, we only need to solve it according to the first method. For interrupt conflicts, it may be more troublesome to operate. First, enter the device manager and check the IRQ interrupt of the hardware you just replaced. Then manually set the IRQ in it to eliminate the interrupt conflict problem. If the problem still cannot be solved, then you need to enter the BIOS and turn off the devices that are not used on the computer. In this case, you can free up a lot of IRQ interrupts. Of course, hardware such as memory modules and network cards will notChanging one slot or changing the slot can sometimes solve the problem, because this will change the IRQ interrupts on the hardware. At this time, we can enter the BIOS and reopen the Reset Configuration Data selected in PNP/PCI, that is Set to enable, then the computer will clear the PCI device table and re-allocate IRQ interrupts, so that the probability of conflict again will be very small. The last situation is to replace the hardware. This situation is basically due to the fact that the equipment is very new.

It is relatively rare for the computer to have no sound after installing hardware devices, but it still happens. I've encountered more than a dozen cases of computer repairs, so I'm prepared.

(2) Incorrect BIOS settings cause the computer to have no sound

The reason for this situation is that some novices have just started to learn BIOS settings. Caused by accidentally setting the wrong options in the BIOS. This situation is more troublesome for novices, because they don’t know where they have just been set when looking at the BIOS. Since we made the changes in the BIOS, even if we redo the system, the computer will still have no sound. There are only three ways to resolve this situation.

1. Find the BIOS sound card option and change it back. The following introduces a common BIOS modification method. First enter the BIOS, select I/O Device configuration, Onboard AC97 Audio Controller, and change it to Enanle or Auto. My computer is from HP. The BIOS of other computers may be different from mine. But just find the corresponding words and enter the settings.

2. Restore the BIOS to default. Enter the BIOS and select Load Setup Defaults BIOS or something similar to Restore Setup Defaults. I personally recommend this method. For friends who don’t know how to set it up, this method is the simplest and most effective.

3. Discharge the BIOS. This method requires disassembling the chassis. Remove the BIOS battery. Just connect the positive and negative poles to discharge. I won’t say much more about this method.

　(3) What to do if the computer suddenly loses the sound

Some friends have a strange problem with the computer having no sound. They suddenly lose the sound while using it. Logically speaking, I haven't made any changes. There should be no problem with the system. There was sound before, which means there is no problem with the graphics card. The probability of hardware device problems is extremely small. This kind of problem often troubles many friends. Today, I will explain to you several solutions to the problem that the computer suddenly has no sound while using it.

When such computer problems occur, the first step is toRecall whether you opened any software when your computer suddenly had no sound. Many software conflicts will also cause the computer to have no sound. Some of these failures are because the old sound card does not support multiple audio streams and does not support the ACPI interrupt sharing function. If this is the reason, you can update the software or check if your sound card has the latest one. Of course, if there is no solution, you can also send your feedback to the manufacturer.

Secondly, it is recommended to reinstall the sound card driver. The most standard solution is to boot into safe mode and uninstall the sound card (it will not be automatically reinstalled at this time). Next, boot into the system normally and reinstall the sound card driver according to the prompts. Enter the control panel to check whether the various settings are correct. If all are correct but there is still no sound, you can consider whether the sound card is broken. If it is integrated, you may need to replace the entire motherboard. Of course, before this happens, it's best to confirm whether the sound card driver you installed is correct. The safest thing is to download it from the official website.

(4) What should I do if there is still no sound after updating the sound card driver?

As we all know, if there is no sound card driver, the computer will definitely have no sound. The current ghost system is usually installed after All drivers will be installed automatically. However, many friends often find that the sound card is not missing after installing the system, but there is still no sound. At this time, we can try to download a sound card driver from the official website of our computer system.

If the sound card is installed and our computer still has no sound, and there is indeed no problem with the sound card, we can check to see if the sound card driver is disabled. Because the sound card will be temporarily disabled when installing some software, and the software will automatically re-enable the sound card driver after the installation is completed. If there are unexpected problems such as installation errors and so on. Then the result can be imagined. Regarding the sound card being disabled, we can try the following methods to reopen it.

First enter the device manager, expand the "Sound, Video and Game Controllers" option, find the sound card item, right-click to turn it on (if the sound card driver is disabled, there will be a small speaker icon in front of it. Cross.), another possibility is to turn off the sound in the sound properties. The solution is to first enter the control panel, open the "Sounds and Audio Devices" option, select "Volume" in the pop-up properties window, and then adjust the sound to the appropriate position. If there is no "Speaker" icon in the lower right corner of your desktop, you can also check "Put the volume adjustment icon into the taskbar". After exiting, you will find that the problem of no sound on the computer has been solved.

(5) Solutions to the problem of no sound on the computer due to viruses

Many friends have encountered this problem.There is a similar problem. After using anti-virus software to check for viruses, the computer has no sound. In fact, this is caused by the virus infecting the audio files. The anti-virus software cannot remove the virus, so it can only delete the infected files together.

When encountering this situation, it is actually easy to solve. Generally, anti-virus software does not delete virus files directly after deleting them. It will be saved in the backup directory. Just in case accidentally deleting the file causes various system problems, we can find it in the anti-virus record and restore it. However, this can be said to be a temporary solution rather than a permanent solution. Although the sound is back, the virus is also back. In this case, we can write down the name of the deleted file and then copy a new one to another good computer. , just paste it into the same location. Of course, you can also extract it from the ghost system package.

Another solution to this problem is to delete the driver and reinstall it. This method can be solved if the virus infects audio driver files. But if it is the main audio program, this method is useless.

(6) What should I do if there is no small speaker icon in the lower right corner of the computer?

Many friends may have encountered the problem that there is no small speaker icon in the lower right corner of the computer when using the computer. The solution to this kind of problem is very simple. Before solving it, you must first determine what the problem is. Except for hardware problems with the audio device, there are generally two reasons why there is no small speaker icon in the lower right corner of the computer. The first is a problem with the sound card, and the other is such problems caused by improper settings. For some novice friends, it is easy to distinguish between the two situations. If it is caused by the sound card, then not only will there be no icon in the lower right corner, but there will also be the symptom of no sound from the computer. If your computer still has sound, it is caused by your improper settings. It is very simple to encounter this reason. You only need to enter the control panel and set it.

If it is the first situation, you can check in the device manager whether your sound card is installed normally (it is not installed successfully, or if there is a problem, there will be a yellow question mark). At this time, you can download a driver. Just update your life or driver wizard (the software will automatically prompt you which ones to update). If it is the second case, you need to enter the control panel. After entering the rear panel, click Sound and Audio Devices and put the volume icon into the taskbar. If it doesn't work, it may be caused by the loss of the system file sndvol32. At this time, you can copy a good one to another computer, or you can extract a copy from the system ghost package and put it under c:\windows\system32.
