Does the computer have no sound? This topic has been heard countless times in my ear, and the troubleshooting is also solved by the previous groping and can now quickly find the reason. But for novice friends, you may not know where to start. For why the computer will have no sound, there is no countermeasure. Today, the computer Pepsi.com editors around this issue will give a detailed introduction to the novice students.

There is no sound in the computer, but the reason is nothing more than two, computer hardware problems and software problems. The hardware problem is mainly the sound card is broken, or the output sound interface is damaged. Generally, the sound card hardware is rarely damaged. The author has to encounter the lack of sound caused by the hardware problem. The software problem is more common and the computer has no sound. So how do you judge whether it is a hardware problem or a software problem? Let's take a detailed explanation.

Generally dealing with computer failures, we are all software first hardware. If your computer has no sound, please try the following solutions, which can generally be solved.

One: If there is no sound in the computer, please check if there is a sound control icon in the task bar on the bottom right of the computer desktop, as shown below:
Computer desktop sound icon as shown above, if there is this icon, the sound card is installed in There is no problem on the computer, then click the sound control icon with the left mouse button, the sound volume adjustment switch control window will appear, check whether the volume is adjusted to the lowest, is it checked the mute, and previously helped many novice friends When dealing with a computer without sound, many of them either turn the sound to the lowest level or check the mute, which causes the computer to have no sound. This is a low-level mistake that novice friends often make. If the above volume control icon is not found on the desktop of the computer, it may be a driver problem. If you look at the driver problem, you will know how to reject it. Some of them are not displayed. The way to display it is as follows: If there is no "Nothing on the right side of the taskbar" Speakers, go to Start---Settings--“Control Panel--Sound and Audio Devices” command, open the "Sound and Audio Device Properties" dialog box, as shown below: As shown above, put √ Click to confirm that there will be a sound icon in the task bar on the bottom right of the desktop. Check again, whether the volume is adjusted and whether it is muted. After the break, the computer usually has a sound. You can also click the <quo;sound> tab in this dialog box, and then click one of the program events (such as a program error) in the “Program Events” column, select a sound category, and then click on the right side. ; Preview & rdquo; button is black. If it is black, the sound card is normal. The cause of the malfunction may be that the system volume is too small, or the mute is set, or the speaker is faulty. Other reasons: If there is no sound card option in the “Device Manager” window, and the sound card is an integrated sound card, then restart the computer and enter the BIOS program. Then check if the peripheral options in the BIOS are set to “Disabled”, if so, change it to “Enable” If this setting is I “Enable”, it may be that the motherboard sound card circuit is damaged, and the sound card circuit can be repaired. Can only be taken for repair. Second: If the computer has no sound, please check if there is any problem with your speaker or ear, whether the speaker or ear audio cable is well connected with the computer, and the interface is plugged in.

It was previously found that when a friend used a speaker or an earphone, there was no sound because the audio cable was connected to the computer. This is also a very low-level error. How can there be sound when no signal is connected to the speaker? ? Some of them are directly connected to the microphone interface of the computer. They all look funny. The computer interface has an audio interface and a microphone. Everyone must look at it. There are icons on it. It is obvious that the rookie does not understand. You can ask the people around you and see the manual is stronger than anything. If there is no sound in the computer before, if there is no sound, check the ear or the speaker is damaged, you can take a good try.

It should also be noted that the general desktop computer will have 2 pairs of audio interfaces, distributed in the front and back of the chassis, so if the front interface is useless, you can try the rear socket. Because some computer installers may forget to connect the socket signal line on the front of the host to the motherboard. I have encountered many of these situations at this point.
