Every time the computer is turned on, there is no sound, and I have to pull out the speaker plug to

If there is no sound on the computer, you can analyze it by following the steps below: First, you must confirm that the hardware is fine. You've already said that 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 you have an onboard sound card, it's a good idea to install the drivers provided on your motherboard's driver disk.

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, the task is in the lower right corner.

There will be a small horn in the bar.

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

To do this, double-click the taskbar.

In the pop-up "Volume Control" dialog box, check whether the volume is turned off to the minimum or set to mute in the "Volume Control" and "Waveform" dialog box.

If these two options are not available in the dialog box, click on the "Options" menu - select "Properties" - select "Volume Control" and "Waveform" in the "Show Volume Controls" and then set them correctly.

In fact, many times, the reason why the computer does not work properly is a small fault, a soft fault, careful analysis, many times can easily solve the problem. What should I do if there is no sound on the computer, follow the following steps to solve the problem of no sound on the computer: There is no sound on the computer

The computer does not have a sound card, make sure your computer has a sound card (isn't that nonsense?). If you don't have a sound card, your computer will have no sound, yes, then take a step, the computer has no sound may be two: see if your computer is set to mute, the computer has no sound may be three:

Take a look at your computer system.

Is there a sound card driver made? Right-click My Computer, then select the Properties command, and then click Device Management.

There is no correct driver (or basically no driver), so your computer must have no sound, what to do, install the computer sound card driver is OK, find your motherboard disc and put it in to install the sound card driver. If you don't have a disc for the motherboard, then you can go online and find the corresponding model of sound card driver. The computer has no sound and may be four:

If there is no "sound, ** and game controller", then check whether the sound card is broken, disassemble the host, take out the sound card and install it, and then turn on the computer to see how the situation is, if it is still the same, then take your computer sound card out of another computer to try to see if it is recognized, if not, it may be that your sound card is broken, take it to repair, or replace it with a new one. Resources.

Take the following measures:

1. Check whether the sound card, cable, speaker and other devices 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.

3. Right-click "My Computer" --Properties--Hardware"--Device Manager", and open "Sound, ** and Game Controller" Is there any problem, that is, see if there is a yellow one in front? If so, uninstall it, then put it into the CD drive and reinstall the drivers for this device.

4. If the "Device Manager" - Sound, ** and Game Controller" is no sound card hardware, then you have to find your sound card, including the integrated sound card, the model must be accurate, after confirming that the sound card is found, then put it into the system drive disk, install the sound card driver.

5. When there is sound but no small speaker, open the control panel --- the sound and** the volume --- the device, and put the check mark before "put the volume icon into the taskbar", and there will be a small speaker in the taskbar after restarting.

6. When there is no sound and no speaker, open the control panel--- add and remove programs--- add and delete Windows components, put in the CD drive, put the check mark in front of "Accessories and Tools", click "Next", the system will prompt you to install new hardware, and follow the prompts to install.

7. If you can't solve the problem, 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, there is a prompt of "AC chip cannot be found", 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 conflict. This has to be addressed step by step for different causes.

9. You can gently pat the shell of the computer body, and the laptop can cover the lid with a little more force than usual, so that some loose parts can be restored, and then reboot after shutting down for a period of time, and sometimes the sound problem will be restored.

I've seen a kind of computer that cut corners before, and the jacks on the front and back panels are connected in parallel with cables.

There may be one of the following reasons why there is no sound when the speaker is plugged into the main computer unit:

The power to the speaker is not turned on, or the volume is turned down. Check whether the power of the speaker is turned on, and adjust the volume of the speaker.

The volume of the computer is turned down or muted. In your computer's system settings, check whether the volume is down or muted, and if so, turn the volume down or unmute.

The cable connecting the speaker to the computer is loose or damaged. Check that the cable is plugged in tightly, or replace the cable.

There is a problem with the sound driver or sound card driver. Check that the sound card drivers are working properly in your computer's Device Manager, and if there is a problem with the driver, you will need to reinstall or update the driver.

There is a malfunction in the speaker itself. If none of the above methods solve the problem, it may be that the speaker itself is faulty and needs to be repaired or replaced.

It should be noted that if there is no sound when the computer is plugged into headphones or other audio devices, there may be a problem with the computer itself, such as a faulty sound card, etc., which needs to be further troubled and repaired.

Check the computer and speaker separately to determine the scope of the fault. Method:

2. Click "My Computer" on the desktop, properties, hardware, device management, and observe whether the sound card is driven, whether there is a red or yellow question mark. If there is a problem, deal with this device first.

3. Double-click the small speaker in the lower right corner of the desktop, and the pop-up screen will check whether the speaker is muted, if so, cancel. And place the left and right balance sliders in the middle position.

4. At this time, the earphones should have sound. Pull out the headphones, plug in the speaker input plug, and see if there is any sound, if there is, it is normal, if there is still none. Observe whether the audio power indicator is on, and then listen carefully to whether the speaker has a rustling sound, and if there is a rustling sound, it is generally that the contact of the audio input plug is not good or the internal line of the input line is broken.

If you follow the vine, you can find the problem.

Plugged in the wrong plug or not plugged in properly.

The computer is muted.

The volume of the stereo has been turned down.

The stereo power is not on.

The computer sound card driver is not installed.
