That's the problem with the binding post, you can try to unplug the binding post and then connect it again. If it doesn't work, then there is a problem with the contact of the binding post, then it is just a matter of changing the wire. What is certain is that the contact is poor, so let's see if it depends!! Hope to adopt!!

I used to be like that.

The line is not bad. The connector can be fully inserted into the interface.

You see if the joint is partially exposed.

Maybe you accidentally kicked the line with your foot, so let it go.

Generally, when dealing with computer failures, we first deal with software and then hardware. If there is no sound from your computer, please try the following solutions, which can be solved.

Method 1: Check the sound control icon.

If there is no sound on your computer, check whether there is a sound control icon in the taskbar at the bottom right foot of your computer's desktop.

If there is this icon, it means that there is no problem with the sound card installed on the computer, and 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, whether the mute is checked, and many novice friends have been helped to deal with the computer no sound in the past, many of them have either turned the sound to the lowest, or checked the mute, resulting in no sound on the computer, which is a low-level mistake that novice friends often make.

If you can't find the volume control icon on the computer desktop, it may be a driver problem, and the driver problem will know how to decide if you look at the following, and some are not displayed, so the way to make it appear is as follows:

If there is no "Speaker" on the right side of the taskbar, go to Start --- Settings - "Control Panel--Sound and Audio Devices" command to open the "Sound and Audio Device Properties" dialog box. After typing, click to make sure that there will be a sound icon in the taskbar at the bottom right foot of the desktop, and then check it, whether the volume is adjusted well and whether it is muted, and the computer generally has sound after resting.

You can also click the Sound tab in this dialog box, then click one of the program events in the Program Events bar (if the program errors), select a sound type, and see if the Preview button on the right is black. If it is black, the sound card is normal, and the fault may be due to the system volume being too low, or mute, or the speaker is malfunctioning.

Hello friends:

There is no sound from time to time, which is generally caused by poor contact with the output socket of the headphone or subwoofer, it is recommended to plug the jack or plug it in tightly.

Hope it helps you and I wish you happiness

Maybe you have ordered mute by mistake, maybe you have used the computer itself for a long time, and the line contact is poor, there are many reasons, first rule out the setting problem, if not, go to the computer city to repair. Thank you!

First of all, install the motherboard's driver. Then install the driver of the sound card. The reason is mainly due to software conflicts. It has nothing to do with anything else.

There is no sound problem on the computer, such as no sound when the computer is turned on, and the small speaker in the taskbar is missing, which often makes the rookies at a loss and don't know what to do. In practice, everyone will encounter similar problems. I've come across it three times on my computer.

After repeated exploration, I finally found a few solutions. Now I dedicate it for the reference of netizens.

First of all, the computer is silent, but sometimes the problem is more complicated, involving both hardware and software problems. Therefore, it is necessary to find out the cause first, see if the software or hardware is malfunctioning, and then prescribe the right medicine for the problem. Don't mess around with unknown reasons, if you don't know the front, the system will be paralyzed, and the trouble will be big.

1. Check whether the sound card, cable, speaker and other equipment are connected normally; Run anti-virus software for anti-virus;

2. Right-click "My Computer" -- Properties -- Hardware -- Device Manager, and open "Sound, ** and Game Controller" to see if there is any yellow in front of you? "If so, reinstall the driver for this device to solve the problem;

4. When there is no sound and no speaker, open the control panel--- Add and remove programs--- add and delete Windows components, put a check mark in front of "Accessories and Tools", click "Next", and then, shut down and restart, the system will prompt you to install new hardware, follow the prompts to install;

5. Uninstall the sound card driver, reinstall or upgrade the audio driver;

6. When the sound card driver is installed, the prompt "AC chip cannot be found" appears, it may be that the computer is poisoned, or the sound card driver has been deleted by mistake due to illegal operation, or there is an internal software conflict. The solution is to reinstall the system and drivers.

7. Simply ignore it, wait for a period of time after shutting down and then turn it on again, sometimes the sound problem will solve itself. You might as well give it a try.

It is also possible that it is poisoned, and it is recommended to kill the poison.

Supplement an unconventional solution,Recently, I have also encountered such a problem,After you ruled out,Mute,Hardware failure and other conventional solutions,That is, there are drivers and icons,There is sound at the beginning of boot,Gradually, I don't know how long there is no sound,Restart is effective,But the problem may still appear,It may be that the driver and hardware are not matched,It may be caused by upgrading the sound card driver,I used the driver wizard,So I finally uninstalled the latest HP definition audio codec,The driver wizard will automatically back up the old version,Or update a public version by yourself,In short, uninstall the current sound card driver,Reinstall may solve the problem。
