Why can t the computer sound come out?

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" for any problems, 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 you don't see the small speaker, don't panic, just open the control panel --- the sound and the --- volume of 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, 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.

The sound card driver is not compatible with the hardware. Uninstall the existing driver and reinstall the original driver.

Right-click on my computer, select Properties - click on Hardware - click on Device Manager - click on Sound. ** and game controllers - (I don't know what sound card chip your motherboard is using.) I had to find it myself.,Generally the first one) Double-click it to the present window to select -Driver-Uninstall.。

How the speaker is not broken words. First look at whether the sound card in the "Device Manager" is normal, if there is a yellow icon on the left, it means that your sound card driver is broken or there is no driver installed (since you were good before, maybe there is some reason that the driver is broken); Check the small speaker in the system bar again to see if the sound is very low or muted.

Let's take a look at your speaker plug to see if it's plugged in.

The power supply is plugged in.

If it's all correct, you can plug it in and try to see if there is a problem with the audio or the computer jack, and then repair it accordingly.

How possible it is to do the sound of the computer audio,First check the sound quality,Then check whether the computer sound card driver is installed、Wrong,If these two are good,Look at the front or back of your audio wire,If the front is not good,It is recommended to plug in the back,Because the front is not good,It is very likely that the line inside the chassis is not plugged in,If it is not good to plug in the back, the sound card chip may be broken,Go to repair,No money less than fifty can be repaired。

The first thing to do is to check whether the sound is in good condition. The speaker can be unplugged for other devices, and if there is sound, the sound is certified. If there is no sound, the sound is broken, and you can choose to repair it or replace it with a new one.

What should I do if the speaker does not sound, if the sound is intact but can not make a sound, first check whether the wiring port is connected. With the terminal connected, you can log in to the control panel, select Add New Hardware, and shut down the computer when you're done. Then restart your computer and see if the situation is resolved.

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.

Uninstall the sound card driver, reinstall it, or upgrade the audio driver. When the "AC chip cannot be found" prompt appears when installing the sound card driver, 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.

Your problem needs to be typed, so you need to wait patiently, Xiaomi will sort out the plan for you immediately! 珞

Hello dear, I have made an answer to your question, it is like this, I helped you sort it out!

There are several reasons why the amplifier does not make sound:

1. Poor contact with sockets and signal wires. Check that the speaker is energized and that the signal lines are in good contact.

2. The most common fault of the power amplifier is the bad capacitor or burning the power amplifier tube, which has the problem of our use, but most of them are unstable in the equipment itself.

3. Some power amplifiers will have a channel without sound failure, the problem is still the circuit problem inside.

4. As for other faults, there are other problems such as bad contact of power amplifier volume potentiometer, unbalanced left and right channels, too frequent protection function, poor contact of the rear panel working transfer switch and signal socket, in short, power amplifier is a kind of electrical equipment that is more prone to failure in the audio system.

5、The most common failure of the speaker is of course the speaker problem,It can be said that the most likely failure in a sound system is to burn out the speaker,Of course, there are human factors,But most of them are the quality problems of the speaker itself。

6. Another common fault of the speaker is that the wiring port is aging and the contact is poor, especially the speaker that often flows is prone to this failure.

4. If the positive and negative power supply is normal, check whether the amplifier tube in the power amplifier circuit is damaged.

There is a voice to ask questions, but not a voice.

That's it, it's always hot, did he burn it?

Answer the solution: to determine whether it is a power amplifier failure, you can turn off the power amplifier for half an hour, or let the power amplifier cool down and not connect the load, check the power amplifier signal light. In order to rule out whether the amplifier is faulty.

That's right, dear. In the operation of the IP network broadcasting system, it is found that the overall sound of the constant pressure speaker is small, and the power amplifier equipment is hot and accompanied by the phenomenon of protection.

First, check whether the wiring is plugged in, whether the speaker is turned on, and whether the volume is turned off. Then double-click the volume icon in the lower right corner of the desktop to open the advanced snake, turn the main volume and waveform to the highest, if there is no sound suggest to take the speaker to the neighbor's house to try, the sound is okay, then ask someone to reinstall the system!

1. The speaker is broken.

2.Speaker cable issues.

3.The computer is muted.

4.The computer sound driver is lost.

You can use headphones to test if there is any sound and rule it out.

Check to see if the thread is loose.

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 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.

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

1. Set it up first: Control Panel - Sound Device - Volume - Put the volume icon into the taskbar - OK, check Mute to cancel.

Take the speaker and listen to it. If there is no sound, the speaker is broken.

If there is a voice. It's a problem with your computer's volume settings. Or maybe it's a sound card driver issue.

Is there a problem with the machine's sound card?

What about drives?? And also.

Is your machine overclocked? Overclocking is also not a good thing.

Also, check if mute is selected in all the sound options in the sound properties.

And are you sure the stereo has electricity?? Is the headphone jack on the back plugged in??

How many headphone jacks are there on the case??

Generally the jack on the panel is plugged into the headphones.

There is no sound in the stereo.

Only the headphones have sound.

Also, are you sure the speaker isn't broken?

After the problem is resolved.

Don't forget to give me points.

You can use Kaishouyu to find the fault one by one: 1. Check whether the sound card, cable, speaker and other devices are connected normally 2. Reinstall the driver of this device to solve it; 3. When there is sound but no speaker, open the control panel, sound and ** device, volume, and check in front of "put the volume icon into the taskbar"; 4. No sound and no speaker, open the control panel, add and remove programs, add and remove Windows components, put a check mark in front of "Accessories and Tools", click "Next", and then, shut down and restart, the system prompts to install new hardware, and install according to the prompts; 5. Uninstall the sound card driver and re-install or upgrade it 6. When installing the sound card driver Qinqi program, there is a prompt of "unable to find the AC chip", it may be computer poisoning, or the sound card driver has been deleted in violation of the operation, and the internal software conflicts. The solution is to reinstall the system and drivers.

7. After shutting down, wait for a period of time to restart the device"

Remember.
