What if the computer voice suddenly speaks without sound?

1. The computer microphone suddenly lost its sound.

At first glance, you are all amateurs, and you don't know where you copied a lot of things. You have a headache, don't pretend to understand.

First run dxdiag to check whether the sound card driver is correct.

Then open the control panel to find the sound and audio management device, double-click it to open it, and then select the hardware under the voice test to see if the microphone has sound.

If there is sound, the microphone option is turned off. Just go to the audio control and eliminate the ticking of the microphone.

If there is no sound, one is the equipment problem, and the other is the replacement of the drive.

The simplest method

Search for "driver's life" or "driver's guide" online, and then install your own operation. Generally speaking, you can upgrade the driver. If the upgrade fails, you will uninstall and reinstall.

The computer suddenly lost its sound. What happened?

1, Trojan horse caused the computer to suddenly have no sound. If we don't change the computer and the computer suddenly doesn't sound, we'd better use Kingsguard to quickly shut down the computer and check whether there is a Trojan horse in the background.

At the same time, Kingsguard will also check some problems of the system to repair while killing Trojans. 2. The driver problem caused the computer to suddenly have no sound. If the system is safe, we need to check whether the driver problem causes the computer to suddenly have no sound.

Turn on the reloading system function of Kingsoft Guardian. Click "Install Driver" in the lower left corner to enter the driver installation, and check whether the audio driver is in the "Problem Driver" column. If it exists, click Repair.

You can also update the audio device driver in Driver Update on the right. 3. Setup problems can also cause the computer to suddenly have no sound. Double-click the small speaker icon on the tray in the lower right corner of the desktop to see if it is mute or the volume is too low.

If there is no small icon in the lower right corner, open Start-Control Panel-Sound, Voice and Audio Devices (XP system, similar to Win7), and select the Voice tab to check whether the default device at the voice playback place is correct. Click the volume to see if the volume setting is normal.

If the default device at Sound Playback shows "No Playback Device" and the driver is installed normally, the device is disabled. Right-click My Computer-Properties-Hardware Tab-Device Manager to see if there are any devices with wrong numbers under "Video, Audio and Game Controllers". If so, right-click to enable it.

If the audio service is not running, the computer may suddenly lose its sound. Enter start audiosrv in start-run (you can enter Win7 in start-search box) and press enter. More solutions to related problems can be found on Baidu's "Installer System" website, which has detailed tutorials.

3. The computer suddenly has no sound. Chatting with friends, suddenly there is no sound, nothing.

1. Press F8 when starting the machine until advanced options appear. Select Last Known Good Configuration and press Enter to repair.

2. This simple method can be restored by the system that comes with the system, and it can be restored to the state without this fault. 3. If the fault still exists, please reinstall the sound card driver.

The common faults of sound card and speaker mainly include mute, low sound, only one speaker has sound, tone sandhi, sonic boom, crackle and so on. The main reasons for this failure are mute, low volume, sound card driver problem, damaged speaker, damaged sound card module, BIOS setting problem, sound card conflict with other devices, poor sound card contact, sound card damage and so on. Troubleshooting methods for sound cards and speakers are as follows.

The troubleshooting method of computer mute 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, and the failure may be caused by the low system sound, mute setting or speaker failure.

You can continue to check whether there is sound output through headphones. If there is, it is the speaker's failure. (2) If there is no "small speaker" on the right side of the taskbar, click the "Control Panel/Sound and Audio Devices" command to open the "Sound and Audio Devices Properties" dialog box, click the "Sound" tab in this dialog box, click one of the program events (such as program error) in the "Program Events" column, select a sound category, and then check whether the "Preview" button on the right side is.

If it is black, the sound card is normal, and the failure may be caused by low system volume, mute setting or speaker failure. (3) If the preview button in the sound tab is gray, click the control panel/system properties/hardware/device manager command to see if there is a yellow "?" In the device manager window. The options are.

④ If there is a yellow "?" , to see if this option is a sound card device option (there are often keywords such as "audio" or "sound" in sound card device options). If it is the sound card device option, it means that the sound card driver is not installed. Reinstall the sound card driver, and the mute problem can be solved.

(5) If there is a yellow "?" The option for does not involve a sound card device, or there is no yellow "?" Option, and then see if there is a yellow "!" Under the Sound, Video and Game Controllers tab. The options are. If there is a yellow "! ",it may be caused by the mismatch of sound card drivers or the aging of sound cards.

Then delete the band "!" Option, 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, restart the computer and enter the BIOS program.

Then check whether the peripheral option in the BIOS is set to "Disabled", and if so, just change it to "Enabled". If I set this item to "Enabled", it may be that the motherboard sound card circuit is damaged, so I only need to repair the sound card circuit.

(8) If the sound card is not an integrated sound card, open the chassis and check whether the sound card is installed. If it is not installed, start the test after reinstallation; If the sound card has been installed, then remove the sound card, and then clean up the dust on the motherboard sound card slot and sound card (especially check whether the golden finger is moldy, etc.). ). Reinstall after cleaning, and general faults can be eliminated.

(9) If the sound card is not normal, there is something wrong with the sound card. Check whether the sound card is damaged or incompatible with the motherboard by replacing it. If the sound card is damaged or incompatible with the motherboard, just replace the sound card.

How to install the sound card driver: (1) Right-click My Computer/Properties/Hardware/Device Manager, and expand the sound, video and game controllers to see if there is a yellow "?" In front of it. No, yes, which means the sound card driver is missing, and there is "!" No, it means that the sound card driver cannot be used normally. (2) I don't know the sound card model. Look at the expanded strings and numbers under "Sound, Video and Game Controllers". This is your sound card model. You can also "Start"/"Run"/enter dxdiag, open "DirectX Diagnostic Tool"/sound, and look for it from the opened interface.

(3) CD installation: put the driver CD of the sound card into the CD-ROM drive, and right-click "Sound, Video and Game Controller"? No option, select "Update Driver", open the hardware update wizard, and select "Yes, only this time"/"Next"/"Automatically install software"/"Next", and the system will automatically search for and install the sound card driver on the CD. If the CD doesn't have a sound card driver for you, please try another driver until it is finished. (4) Download and install the driver software: 1. There are many websites for downloading sound card drivers. Try to go to the homepage of a comprehensive large-scale website, enter your sound card model in the "Search" text box, press the "Search" button, and select the website where you want to download the driver from the opened interface.

2. In the open website, if the driver software you want is not displayed, you can use the website search engine to search. 3. Pay attention to downloading driver software: First, the brand model should be correct; Second, what system should it be used on; Third, it should depend on the release time of the driver software; The latest driver software may be unsuitable for use; You can download more content and choose what you want to use.

4. The downloaded driver software generally has the function of automatic installation. When it opens, click it to install it automatically. If it cannot be installed automatically, please extract it for later use. Write down the specific path of the software on the disk, such as d: \ ... \ ... ........................

Right-click My Computer/Properties/Hardware/Device Manager, open the sound, video and game controller, and then right-click? No. Sound card option, select "Update Driver", open the hardware update wizard, uncheck "Search for removable media", select "Install from list or specified location"/"Next", select "Include this location in search", and fill in the path of the sound card driver folder to be used in the drop-down list box (d: \ ... \ ... Sound card driver. After installation, it will automatically download and install the latest driver, including sound card, video card, network card, USB and so on. This is a collection of drivers.

4. What should I do if the computer suddenly loses its sound?

1, first check whether there is any problem with the equipment, whether the wires of the interface are correctly inserted, and the wires of the microphone and the sound are different in color, and there is usually a small icon next to them.

If it is not these problems, it may be that the audio output interface of the computer is damaged. It is recommended to find a computer to repair it. 2. See if the speaker in the lower right corner is mute.

Right-click the speaker in the lower right corner of the computer-turn on the volume control-master volume-mute all (cancel "√"), so you can know whether it is muted or not. 3. See if there is a small horn in the lower right corner.

If it doesn't exist, a small speaker will appear after restarting the computer. Right-click the small speaker to check the situation. If there are no speakers after restarting, please open "Start-Settings-Control Panel-Sound, Voice and Audio Devices-Volume-Device Volume-Put the Volume icon in the taskbar (check the previous box)".

4. If the computer has no audio equipment. First, scan the computer with antivirus software to see if there is any computer virus that damages audio equipment.

If not, please go to My Computer-Blank Area and right-click Properties-Hardware-Device Management. If there is a yellow exclamation mark in front of it, there is something wrong with the sound card device and driver.

5. With the help of Master Lu, you can check the specific brand model of the computer sound card driver, or you can check the sound card model in Start-Run-Enter: dxdiag command-OK, and then select the sound. Then Baidu searches for the corresponding sound card driver to download and install.

6. If there is no sound on the computer when playing the video. Web pages generally have audio buttons. When the audio button is off, there is no sound when playing the video.

As long as the audio mute button is activated, the sound can be played normally. .

The computer suddenly stopped working.

Mute: This is the least problem and the most easily overlooked one. Sometimes our computer has no sound, not because there is something wrong with the computer's software or hardware, but because we just mute it.

The solution is simple, just turn on the sound. 2. Sound card driver: This should be the first thing that many people think of when the computer has no sound. Indeed, this is also one of the culprits that often lead to the silence of computers.

First, we find the sound device through the control panel, and then click the sound and audio device (the same as * * * settings, please refer to the figure below). If the pop-up interface is gray, it proves that the driver is not installed. We just need to download a driver and install it. If you don't know what to download, you can download a universal sound card driver and install it. 3. Silent virus: I have never encountered a silent virus, but many online users have. It seems to be called waveform mute virus. The performance of this virus is: when the computer is turned on, it is silent, that is, there is no system startup sound, and the audio of viewing waveform is minimized, so the sound cannot be played. Even if you adjust it, it will automatically mute after a few minutes.

If it is caused by a virus, the solution is to kill the virus. We can kill the virus in safe mode. If not, reinstall the system. 4. The service is not running: This should be a problem that many users easily ignore, that is, the audio service is turned off.

Of course, you may not have turned it off on purpose, but it was banned when the optimization started. Therefore, the audio service is not started when the boot is started, so the computer has no sound. The solution is simple, just start the audio service when the computer is turned on.

The specific implementation method is to right-click my computer, click Manage, find the service option, double-click to enter, find the Windows audio option to see if it is turned on, if not, turn it on and set it to automatic. Computer hardware has no sound 1, and interface problems: whether we use headphones or stereo, we need to connect through a fixed interface. If the connected interface is in poor contact or damaged, the computer will have no sound. If it is a desktop, we can try another interface to see if there is sound. If it is a notebook, we can unplug the headphones or stereo to see if there is any sound. If so, we can be sure that the interface has been damaged.

The solution is simple, just change the interface. If it is a notebook, it may be a little troublesome. Many of them have only one interface. If it is broken, you can't use the stereo or headphones. If you still want to listen to sound with a stereo or headphones, you have to find someone to change the interface. 2. Headphone problem: If you are listening to sound with headphones, if there is no sound, you should try to replace the interface first. If there is no sound, you can change your headphones. If the other party's earphone has sound, it proves that your earphone is broken.

The solution is simple, that is, change a headset. 3. Sound problem: If you listen to sound in stereo, you must first eliminate the interface problem when there is no sound and ensure that there is no problem with the interface. Then there is probably something wrong with the audio. We can use headphones instead and see if there is any sound. If there is, it is a sound problem.

The solution is simple, that is to replace the stereo. 4, sound card problem: this is not easy to judge, to ensure that the above problems are not, then it may be the sound card itself.

Whether the sound card is damaged needs professional maintenance personnel to judge. If so, the problem can only be solved by replacing the sound card. Note 1. The service is not running, which should be easily overlooked by many users. When we are sure that there is nothing wrong with other software, let's see if the service is not started.

When there is no sound, the first thing we need to check is the software to make sure it is not a software problem, and then see if it is caused by a hardware problem. 3. Of course, when you encounter audio problems, it may not be the damage of the audio itself, but the damage of the line used as a link. Of course, it is difficult for ordinary people to judge. If there are conditions, you can also test whether it is caused by line damage. At this time, you only need to replace the line.

6. The computer suddenly has no sound solution. What if the computer suddenly loses sound?

A friend said that his computer suddenly lost its sound. What should I do? Then let's try my solution! I hope I can help you!

What if the computer suddenly loses its sound? You can rule it out according to the following conditions.

1. Is the audio power supply not plugged in correctly? Is it loose? Or the earphone plug is loose.

2. Is the computer sound set to mute?

3. Is the player or software playing sound set to mute?

More computers have no sound. Please see: What's wrong with the computer without sound?

What if the computer suddenly loses its sound? Solution:

1. First, open the control panel (where is the control panel) and find the options for sound and audio devices.

2. Turn on the sound and audio devices. If you see that the scroll bar is gray, it may be that your sound card driver is lost and the computer suddenly has no sound. Generally speaking, the sudden silence of the computer is caused by the loss of the sound card driver.

3. Since there is no sound card driver, you can download the driver software update or install the next driver online.

The above is about how to do when the computer suddenly loses its sound, or there are many other reasons that cause the computer to suddenly lose its sound. I will analyze them for you one by one in the future.

7. What is the reason for the sudden silence of the computer?

The computer has a sound card, but there is no sound. Please do the following: 1. Check whether the connection between the host and the speaker is loose or disconnected, whether the power of the speaker is turned on, and whether the volume knob of the speaker is related to the minimum value.

2. For the independent sound card, check whether the sound card is in good contact with the motherboard slot and re-insert the sound card. For the sound card integrated on the motherboard, check whether it is disabled in the BIOS.

Solution: When starting the computer, enter BIOS settings (usually press and hold the Del key), expand "Integrated Peripheral", find the sound card item (usually named AC97 Audio) in the window that appears, set it to "Auto" or "Enable", find the onboard AC97 control, set it to "Enable", then save and exit, and install the sound card driver after entering the system. 3. Open Device Manager to check whether there is any problem with the sound card driver installation.

Solution: Right-click My Computer → Select Properties → Pop-up System Properties window → Select Hardware page → Press Device Manager (D) button → Pop-up Device Manager window → Check whether there is "!" In front of Sound, Video and Game Controller or Multimedia Audio Controller. Or "?" If the driver of the sound card is damaged, please find the driver disk of the sound card and reinstall the driver (if the sound card is integrated with the motherboard, the driver is on the driver disk of the motherboard). If there is still no sound after the sound card driver is installed correctly, please check the following two aspects: 1. The sound card is disabled in Device Manager.

Solution: Go into Device Manager, expand the "Sound, Video and Game Controllers" branch, find the sound card item (if it is disabled, there is an "X" on the front speaker) and select it, then press the "Enable" button in the toolbar. 2. Turn off the volume in the sound properties.

Solution: Enter the control panel, double-click the item "Sound and Audio Equipment" to pop up the window "Sound and Audio Equipment Properties", select the "Volume" page, adjust the volume adjustment slider to a suitable position, put a tick before "Put the volume adjustment icon in the taskbar (I)", and then confirm and exit.

8. What if the computer suddenly stops speaking?

I often encounter the phenomenon that the sound card can't produce sound or the sound is abnormal. How to troubleshoot and make the sound card sound good?

1, the sound card is silent

The default sound output of the system is "Mute". Click the small sound icon (trumpet) in the lower right corner of the screen, and the volume adjustment slider will appear with the option of "Mute" below. Click the check box in front and clear the check box in the box to pronounce normally.

The sound card conflicts with other cards. The solution is to adjust the system resources used by PnP cards so that these cards do not interfere with each other. Sometimes, when I open the device manager, although I don't see the yellow exclamation mark (conflict sign), the sound card just doesn't sound. In fact, there are conflicts, but the system did not detect them. After installing DirectX, the sound card can't produce sound, indicating that the sound card is incompatible with DirectX, and the driver needs to be updated.

If there is no sound in one channel, please check whether the audio line from the sound card to the speaker is disconnected.

2. Play the CD silently

In the case of complete silence, the CD player of Windows 98 has no sound, but the CD player works normally. At this point, you can use a 4-core audio cable to connect the analog audio output of the CD-ROM with the CD-In on the sound card. This cable is provided when you buy a CD-ROM drive.

For the case of only one channel, the output port of the optical drive is generally two lines of signals, and the middle two lines are ground wires. Because the colors of the four audio signal lines are generally different, one-to-one corresponding interfaces can be found from the colors of the audio lines. At this time, the interface on the sound card may not match the audio cable. Just switch their positions and make them match.

3. WAV, MIDI or CD music cannot be played.

WAV music cannot be played because there are multiple Audio Devices under Multimedia → Devices, so just disable one. The problem of MIDI is caused by the incompatibility between 16-bit mode and 32-bit mode, which can be solved by installing software wave table. There is no sound on the CD because the cable of the CD-ROM drive is not connected correctly. There should be no problem after connection.

The sound card is too noisy.

This may be caused by the following reasons:

A, the card is not correct, and the sound card is not closely combined with the motherboard expansion slot. You can intuitively see that the "golden finger" on the sound card is misaligned with the expansion slot reed. This phenomenon exists in both ISA card and PCI card, and it is a common fault. We can solve the problem by trying to insert the sound card correctly.

B, the input end of the active speaker is connected to the speaker output end of the sound card, and the active speaker should be connected to the line output end of the sound card. Its output signal is not amplified on the sound card, and the noise is much less. Some sound cards have only one output. Whether it is line output or speaker depends on the jumper on the card. The default mode is usually speakers, so if necessary, you must unplug the sound card and adjust the jumper.

C. The installed sound card driver version is not good. You can use the driver that comes with the system. If so, you'd better install a special sound card driver. If you have installed the drivers that came with Windows, you can select Control Panel → System → Device Manager → Sound, Video and Game Controller, click each device, and then select Properties → Drivers → Change Drivers → Install from Disk. At this point, insert the disk or CD attached to the sound card and install the driver provided by the manufacturer.

9. What if the computer suddenly loses its sound?

First, the audio settings are as follows: Steps: Start-Run-Service. MSC- Find Windows Audio in Name-Select it with the left mouse button-Click the right mouse button-Select Properties-General-Startup Type.

If you are infected with virus, you should run anti-virus software to carry out comprehensive anti-virus. 2. Open the control panel-Add new hardware-Next. After searching, click No, I haven't added this hardware yet, and then click Next.

In the dialog box that appears, select "Click Finish without turning off the computer, and then restart to add new hardware". Note that this is about shutdown and restart, not restart.

Generally speaking, the problem can be solved after restarting. 3. Right-click my computer-properties-hardware-device manager, and turn on the sound, video and game controller to see if there is any problem, that is, to see if there is a yellow "?" In front of it. .

If so, please uninstall it first, then put it in the CD-ROM drive, and reinstall the driver for this device. 4. If Device Manager-Sound, Video and Game Controller does not have sound card hardware, you must find your sound card, including the integrated sound card. The model must be accurate. After confirming that the sound card is found, put it on the system driver disk and install the sound card driver.

5. When there is sound, but there is no speaker, open the control panel-Audio and Video Devices-Volume, and put a check mark before "Put the volume icon in the taskbar". After restarting, there is a speaker in the taskbar. 6. When there is no sound or speakers, open the control panel-Add and remove programs-Add and remove Windows components, put them in the CD-ROM drive, put a check mark in front of "Accessories and Tools", and click "Next". You will be prompted to install new hardware.

7, still can't solve the problem, so we have to reinstall the system and drivers, all questions will be solved, but the premise is that all kinds of hardware are intact and there is no conflict between software. 8. When installing the sound card driver, the prompt "AC chip cannot be found" appears. It may be computer poisoning, loose plug-and-play of the sound card that leads to poor contact, illegal operation that mistakenly deletes the driver of the sound card, or internal software conflict.

This should be solved step by step according to different reasons. 9. You can tap the shell of the computer body. When the laptop is covered, you can use a little more force than usual to restore some loose parts. Wait a while after shutdown, and then restart. Sometimes sound problems are recovered.
