What if the computer has no sound?

Computer no sound is a very depressing thing, there is no sound problem computer, such as when the computer turned on without a sound, the task bar in the small horn disappeared, often make the rookie helpless, do not know how to be good. In the actual operation of the process, who will encounter similar problems, and friends have been made to sleep hard ann. It is also true that anyone who encounters such a thing will not be at ease ...

Now I would like to introduce you to a common computer without sound processing methods.

First, to confirm the hardware is no problem.

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.

Second, the correct installation of sound card driver

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 you did not find it." "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

Third, if the driver is sure the correct installation, then look at the computer's volume settings.

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, look at the picture below, 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.

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.

Four, the BIOS is not familiar with the user may be mistaken operation shielding the onboard sound card.

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."

After installing the network card or other devices, the sound card is no longer audible

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.
