What if my computer doesn't have a sound?

First make sure your computer hardware is fine.

The speaker is not defective, 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 good, then you can continue to look down.

Properly 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 you did not find it." "Installing the UAA patch will fix the problem."

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.
