Here are three networked laptops that don't have a sound encyclopedia and want to help you:
First, check the taskbar volume icon, whether the click to mute, whether the volume is tuned to the minimum.
Second, check the pronunciation equipment, headphones, speakers, the connection is normal, the socket is inserted right. Whether the headset is working properly. If the power is plugged in!
Third, check the headset speaker volume adjustment switch to the minimum, or mute.
Check the volume of Windows ' own playback software RealPlayer and Windows Media Player, and whether they are reconciled to the smallest, or mute!
Check the BIOS sound setup options. Whether the sound card is set to disable!
BIOS Setup Illustrated Tutorial
Six, check the sound card driver is damaged! If the sound card driver is still there, but there is no sound, only from the new sound card driver!
If you have a computer to buy the original sound card driver disk, then directly oblique load off, and then reload.
Put the drive disc of your sound card into the optical drive and right-click under Sound, video and game controllers? option, select "Update Driver" to open the Hardware Update Wizard, select "Yes, this time"---"Next"---"Install software automatically"-"Next", The system will automatically search for and install the sound card driver in the CD, if the disc is not suitable for you to use the sound card driver, and then another try, until completed.
If you do not have the original tape, refer to the following:
Expand the "sound, video and game controller" under the sound card items, look at the specific model of the sound card, and then the model to search the Internet to download a driver, if not, you can use universal sound card driver!
After the download is saved, right-click My Computer----properties---Hardware----Device Manager, open the sound, video and game controllers, right-click the sound, video and game controllers? sound card options, select Update Driver, open the Hardware Update Wizard, and remove the Search for removable media before the tick, check "Install from list or specified location"---"Next", check "include this location in search" and fill in the path of the sound card driver folder you want to use in the bottom of the list box ...---"Next", the system automatically searches for and installs the sound card driver in the location you specify.
Believe that it should be a sound, if there is no sound!!! I guess I'll have to change the sound card!!
The computer has no sound. You can follow these steps to analyze:
First, to confirm the hardware is no problem. You have said that the horn is OK, the sound card is OK, if you have been tested on other machines is really good, then you can continue to look down.
Confirm that all cables are correct. Then the speaker power is turned on and the volume switch is turned on.
Third, the correct installation of the driver of the sound card, if it is a onboard sound card, it is best to install the driver on the motherboard driver disk provided.
(In fact, the computer is silent, often because the sound card is not properly driven.) In general, after the sound card driver is installed, the task in the lower right corner
The bar will have a small horn icon. )
If you are sure the driver is installed correctly, then look at the volume settings on your computer.
The specific method is: Double-click the small horn in the taskbar icon, in the pop-up "Volume Control" dialog box to see "Volume Control" and "waveform" two items are not to turn the volume to the minimum, or be set to mute state.
If you do not have these two options in the dialog box, click the Options menu-select Properties-In the "show the following volume Control" select "Volume Control" and "waveform" two items, and then set correctly.
▲ Note: Only the driver for the sound card is properly installed before the fourth step is set.
Special Reminders:
In fact, many times, the computer does not work the reason is small fault, soft failure, careful analysis, many times can be very easy to solve the problem.
Often encounter a sound card can not voice or abnormal sound phenomenon.
How to troubleshoot, so that sound card issued a beautiful sound?
1, sound card silent
The system default sound output is mute.
Click on the lower right corner of the sound small icon (small horn), the volume adjustment slider, there is a "mute" option, click the Front of the check box, clear the box tick, you can pronounce correctly.
The sound card is in conflict with other cards.
The solution is to adjust the system resources used by the PNP card so that the cards do not interfere with each other.
Sometimes, open "Device Manager", although no yellow exclamation point (conflict flag), but the sound card is not audible, in fact, there is conflict, but the system is not detected just.
The sound card does not sound when you install DirectX, which means that the sound card is not compatible with DirectX and needs to be updated with the driver.
If it is a sound track, then check the audio card to the speaker line is disconnected.
2, Play CD silent
In the case of utter silence, CD player with Windows 98 is silent, but the CD player works fine.
A 4-conductor audio line is used to connect the analog audio output of the CD-ROM with the cd-in on the sound card, which is provided when the CD-ROM drive is purchased.
For only one sound channel, the optical drive output is generally left and right two lines of signal, the middle two lines for the ground.
Because the 4-line color of the audio signal line is generally different, you can find one by one corresponding interfaces from the color of the audio line.
It is possible that the interface on the sound card does not match the audio line, swap their position, let it match on the line.
3, unable to play WAV, MIDI or CD music
Can not play WAV music is often due to "multimedia" → "equipment" under the "audio device" more than one, then disable a can;
The problem with MIDI is that the 16-bit mode is incompatible with the 32-bit mode and can be solved by installing the software Wave table;
The CD must be silent because the cable to the CD-ROM drive is not connected properly and there should be no problem after that.
4, sound card noise too large
This may be due to several reasons:
A, card is not, the sound card is not with the motherboard expansion slot closely combined, through visual visible sound card on the "golden Finger" and expansion groove reed dislocation phenomenon.
This phenomenon in the ISA card or PCI card, is a common fault, to find a way to plug the sound card can solve the problem.
b, the active speaker input is connected to the speaker output of the sound card, the active speaker Bell in the sound card line-out end, it output signal did not go through the sound card amplification, noise is much smaller.
Some sound card only one output, is line-out or speaker to rely on the jumper on the card, the default way is often speaker, so if necessary, unplug the sound card adjustment jumper.
C, the installed sound card driver version is not good, you may use the system with its own driver, if so, it is best to install a special sound card driver.
If you have installed Windows with your own driver, select the control panel → system → Device Manager → Sound, video and game controllers, points in the device, select properties → driver → change driver → install from disk.
Insert the disk or CD that came with your sound card to install the driver supplied by the manufacturer.
What to do with a laptop without sound and how to solve it?
Troubleshoot the sound card or mistakenly delete the driver problem steps:

What if the computer has no sound? The computer has no sound solution??
Steps/Methods
Now I would like to introduce you to a common computer without sound processing methods.
First, make sure the hardware is fine.
You already said the horn is fine, the sound card is fine, make sure all the connectors are correct. Then the speaker power is turned on and the volume switch is turned on. If you've already tested on other machines that are really intact, you can go ahead and look down.
Correctly install the driver for your sound card
If it is a onboard sound card, it is a good idea to install the driver provided on the motherboard driver disk.
If the sound driver is not properly installed, a yellow "?" will appear in the device management. Or in sound, video and game controllers, voice audio controllers have a yellow "!"
If you are prompted to install the HD Audio sound card driver: "You need the HD Audio bus driver, but not found."
Install the UAA patch to fix the problem (click to go to the download page).
In fact, the computer is silent, often because the sound card driver is not correct.
Under normal circumstances, the sound card driver installed, in the lower right corner of the taskbar will have a small horn icon
If you're sure the driver is installed correctly, look at the volume settings on your computer.
The specific method is: Double-click the small horn in the taskbar icon, in the pop-up "Volume Control" dialog box to see "Volume Control" and "waveform" two items are not to turn the volume to the minimum, or be set to mute state.
If you do not have these two options in the dialog box, click the Options Menu-Select "Properties"-"Volume Control" and "waveform" are selected in "show the following volume control" and then set correctly.
Check to see if the volume mediation switch on the headset is minimized, or mute.
Check the volume of Windows ' own playback software RealPlayer and Windows Media Player, either mediated to the minimum, or mute.
Now some sound card, have interface induction function, such as you plug in the stereo or headphones, will pop up a window, let you choose what you plug in the device, when you choose the wrong, it may cause no sound, here must be set correctly.
Special reminder: In fact, many times, the computer does not work properly because of the small problems, soft faults, careful analysis, many times can be very easy to solve the problem.
Users who are unfamiliar with the BIOS may be mistakenly shielded onboard sound
Enter the BIOS, select I/O Device configuration→onboard AC97 Audio Controller, choose Enanle or Auto.
My is ASUS motherboard, other due to different motherboard, or BIOS version is not the same, there may be some differences, but also basically similar, if it is award bios, into the BIOS in the "intergrated peripherals", and then select "AC97 Audio" Change " Disable "for" Auto "save."
The sound card is no longer audible after installing a network adapter or other device
This problem is more representative, mostly due to compatibility issues and disruption of conflict.
The problem of driving compatibility is better solved, the user can update the driver of each product.
And breaking the conflict is more troublesome.
First into the control Panel → system → Device Manager, query their own IRQ interrupt, and can be directly set IRQ, eliminate conflicts.
If the conflict is not eliminated in Device Manager, the best approach is to go back to the BIOS, close some unwanted devices, and empty out the extra IRQ interrupts.
You can also swap your network card or other device for a slot, which will also change your IRQ interrupts to eliminate conflicts. After changing the slot should enter the BIOS in the "PNP/PCI" item in the "Reset configutionration Data" to enable, empty the PCI device table, reassign IRQ interrupt.
The above is a more common method of troubleshooting without sound.
Often there will be netizens put forward, I play MP3 local, songs have a voice, why open the Web site to see the video will not sound??
Play in the local sound, but also to prove that your sound card, headphones (speakers), drive all normal, basically is the problem of setting up ....
Check the web player to see if the sound is open ...
If you are using IE, turn on the tools---Internet Options----advanced, whether you are open
If you are surfing the browser, in the bottom right corner of the browser, the status bar has a sound icon, you check is mute ...
Of course, other browser settings are similar to the above, but also need to examine themselves carefully.
Conclusion: Text A little more, however, if you carefully read, you can certainly help you solve the problem Oh!
