The computer at home suddenly stopped making sound, and the desktop computer at home suddenly stoppe

The question should not be overly complicated, in my experience:

1. Click on the small speaker in the lower right corner to check whether it is muted

2. Check whether the sockets of the speaker and the chassis are fully plugged in (it is best to plug them in and unplug them again), and then determine whether the sockets are plugged in by the wrong interface (don't make a mistake in the sockets of the microphone and earpiece).

3. Try to replace the rear socket of the case, if the front socket is plugged in, and then the earphones are plugged in the rear socket, you can't hear the sound (blocked).

Generally speaking, a slight movement or a slight vibration should not have much effect on the computer. Only in the case of large vibrations may damage the oscillator element on the motherboard.

You check it in a few steps:

1.Check whether the sound card driver is normal, if you can't adjust the sound volume, it means that there is a problem with the driver, and reinstall the driver.

2.Check whether the speaker power cord and computer cable are connected properly.

3.Make sure the speaker is turned on, and the sound is not the smallest. If you don't have sound yet, try a different speaker or headphones.

If there is still no sound after trying the above, or the sound card cannot be found and does not work, it may be that there is a problem with the sound card on the motherboard. Ask the relevant technician for maintenance.

Best outcome: Poor socket contact.

Worst outcome: The sound card is broken.

Shut down first, open the case, and try the plugs inside by manual The phenomenon you said is because of the poor contact of the socket caused by vibration

Vibration can cause poor contact with the socket, and you should be fine if you mess with the socket!

It should be that the interface is in poor contact.

Summary. 1. It may be that the sound control is muted, check whether the sound control icon in the taskbar in the lower right corner of the computer desktop shows X, and drag the volume bar to the right to dismiss it;

2. It may be that the sound card driver of the computer is uninstalled, enter the sound and audio equipment in the control panel, open the properties of the sound and audio device to check the driver situation, and reinstall the driver to recover;

3. It may be that the sound card circuit of the motherboard is damaged, and the sound card driving circuit needs to be repaired or an independent sound card needs to be purchased to replace the motherboard sound card.

What's going on with the sudden silence on the desktop computer at home.

1. It may be that the sound control is muted, check whether the sound control icon in the taskbar in the lower right corner of the computer desktop shows X, and drag the volume bar to the right to dismiss it; 2. It may be that the sound card driver of the computer is uninstalled, enter the sound and audio equipment in the control panel, open the properties of the sound and audio device to check the driver situation, and reinstall the driver to recover; 3. It may be that the sound card circuit of the motherboard is damaged, and the sound card driving circuit needs to be repaired or an independent sound card needs to be purchased to replace the motherboard sound card.

The new computer, which was supposed to be fine, suddenly lost its sound.

What is going on with the output device not found in the display.

Wait a minute, are you on silent mode?

No. I can still know the normal operation.

In this case, most of the problems occur with the sound card hardware, check the method: 1. The system prompts "The audio output device cannot be found", that is, the sound card device in the user's host is notified, and the system cannot recognize it, so the device will naturally not be used; 2. Open the "Device Manager" window and view the "Sound, ** and Game Controller" items. If it is the name of the sound card device, the computer suddenly has no sound, and the prompt is that the audio output device cannot be found.

How to solve it. 1. Press the [win+r] key combination to open the operation, and enter: Click OK to open the service.

Still can't do it.

Computer poisoning is usually solved by reinstalling the system, and the anti-virus is sometimes not complete.

Of course, when reinstalling the system, you need to format all partitions to ensure that there are no viruses left.

In terms of system: the corn system is relatively easy to use, not only stable, but also very smooth.
