What if the computer doesn't sound?

1, 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.

2, 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

3, if sure the driver is installed correctly, then look at the computer's volume settings.
