What s the matter with the computer not ringing, there is no sound at all

First, first confirm that the hardware is fine. If the speaker is fine, the sound card is fine, and if you've tested it on other machines and it's really good, then you can read on.

2. Make sure all the cables are exactly right. Then power on the speaker and turn on the volume switch.

3. Install the driver of the sound card correctly, if it is an onboard sound card, it is best to install the driver provided on the driver disk of the motherboard.

In fact, the computer does not make a sound, and many times it is because the sound card is not driven correctly. In general, after the sound card driver is installed, there will be a small speaker icon in the taskbar in the lower right corner. ）

Fourth, if you are sure that the driver is installed correctly, then take a look at the volume settings in the computer.

The specific method is to double-click the speaker icon in the taskbar, and check whether the volume is turned off to the minimum in the "Volume Control" and "Waveform" dialog box in the pop-up "Volume Control" and "Waveform".

If you don't see these two options in the dialog box, click on it.

Options menu - select "Properties" - select "Volume Control" and "Waveform" in "Show the following volume controls", and then set them correctly.

Note: Step 4 can only be set up after the driver for the sound card has been installed correctly.

definition or other long strings in English, or with a yellow question mark. Situation 2: Click on the lower left corner of the desktop to start all the settings in the Control Panel Sound & Audio Devices are grayed out, that is, they are not available.

If either of the above two situations exists, you go straight to it.

**"Driver Wizard" software, after installing it, double-click to open Driver Update Tick "Sound** and Game Controller" Start Update Restart the computer after the update is complete. If the above two situations do not exist, please follow the steps below. Step 1:

If there is no small speaker in the lower right corner of the desktop, start the Control Panel Sound & Audio Devices tick on "Put the volume icon into the taskbar" OK. zs

The computer is normal, and there is no sound solution.

Hardware Issues: Right-click on My Computer --Properties --Hardware--Device Manager--Sound. Video & Game Controller --Right Click--Reaitek High Definition Audio--Update or Scan, Uninstall Reinstall Reinstall Boot.

Microphone Problem: Adjust the microphone: from the control panel --- to the high old to clear the sound pin dust configuration - mixer - replay - pull down on the right - appear rearpinkin - hit x to mute it, and push the rest up.

Record --- stereo mix --- hit x mute it.

Insist on whether the sound card driver is installed correctly, turn on Kingsoft Guard, and enter the "Refill System" tab - click the button "Install Driver".

Open the "Install Driver" interface, it will automatically detect the driver of the audio card that you have not installed, click "Install"; If your audio card driver is damaged, click "Repair" to make sure your computer is back to normal use with sound.

The "Driver" function will also automatically remind you that the driver can be upgraded to a version certified by the Microsoft logo; If you don't want to upgrade and don't want to be prompted to upgrade again, you can click "Don't prompt again"; Restore the upgrade to the waiter, click "No longer prompt the driver for the upgrade" will restore the prompt.

Left-click on the volume icon in the work column of the computer desktop to see if it is selected to mute, and whether the volume is turned to the minimum.

It may be that the speaker mute key on the keyboard was accidentally pressed.

Go into the device manager and see that the sound card is still not there, or maybe the driver has fallen out and needs to be reinstalled.

Check if you have mute set? Or whether the sound card driver is normal, it is recommended to reinstall it or upgrade it.

Probably:1Mute is clicked in the lower right corner.

2.The driver is wrong, you can reinstall it and delete the original one.

3. The power supply or cable of the speaker is not connected.

The socket is broken... The socket for plugging in headphones or speakers is broken, do you try to change the socket?

What system are you using, if it is win 7, you try this: Control Panel (select Category View) - Hardware & Sound --- Manage Audio Devices--- To display all disabled devices, disable all the speakers that are ready to go, and then enable them one by one and see if it works.

If you have an XP system, please check the sound of your computer and double-click on the small speaker icon in the bottom right corner. The full open inside is the largest, you take a look. Or just adjust it yourself in the sound in the control panel.

The premise I say is that your computer's sound card, drivers, and speakers are fine.

Workaround:

1. Check whether the sound card, cable, speaker and other equipment are connected normally; Run Antivirus back.

The sound card driver has been deleted by you, go to the next universal driver!

Hello! You check the line! Bad contact!

The easiest way to do this is to reinstall the system

It is also common for the sound card to not sound and the small speaker to disappear due to sudden crashes. Therefore, it is necessary to find out the cause first, see if it is a software failure or a hardware failure, and then prescribe the right medicine for the problem and solve it properly. We must not mess around for unknown reasons, because if we don't do it, 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; If you have a virus, you should run antivirus software for full antivirus.

2. Open the control panel--- Add new hardware--- Next, after the search is completed, click "No, I haven't added this hardware", click Next. In the dialog box that appears, check Click Done, shut down the computer, restart to add new hardware. Note that this refers to shutting down and then starting, not restarting.

In general, the problem can be resolved after rebooting.

6. When there is no sound and no speaker, open the control panel--- add and remove programs--- add and delete windows components, and put in.

7. If the above steps do not solve the problem, then you have to reinstall the system and drivers, and all problems will be solved, but the premise is that all kinds of hardware are in good condition and there is no conflict in the software.

8. When the sound card driver is installed, the "AC chip cannot be found" prompt appears, it may be computer poisoning, or the sound card is plug and play loose, resulting in poor contact, or it may be due to illegal operation and mistakenly deleted the sound card driver, or internal software conflicts. This is a step-by-step approach for different causes.

9. Simply ignore it, you can gently pat the shell of the computer body, the laptop can cover the lid when the force is slightly larger than usual, so that some loose parts are restored, and after shutting down, wait for a period of time before restarting, sometimes the sound problem will be restored. You might as well give it a try.
