There is a noise in the computer speaker,,There is also a noise when the headphones are plugged in,S

Reinstall the appropriate sound card driver, no, it may be that the volume switch is broken, or it may be that there is interference, and the possibility of dust is basically not.

It should be the poor contact caused by the dust of the chassis or the loose jack, right, if the hardware is loose, can your computer still turn on?

The case headphone jack is not in good contact, plug and unplug it a few times to see the effect, and try a few more times.

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 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, it is located in the taskbar in the lower right corner.

There will be a little horn in it.

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

I turned down the frequency of the sound setting and it worked out perfectly.

1.Sound Card Driver Problem 2 What's Disturbing Take a look at it from a different position! 3 The speaker is broken.

01 Speaker.

First turn off the sound of the computer, and then listen to see if there is any noise, if there is, it may be a problem with the speaker, and the general speaker needs to be replaced if it is broken.

02 Wiring problems.

If it is a desktop computer, you need to observe whether the connection between the computer and the speaker is connected, if it is not connected, it will also make noise.

03 Surrounding settings.

The speaker should be placed away from the main computer as much as possible, and it is best not to put some electronic devices around, otherwise it may also cause noise from the computer.

04 The computer is too loud.

If you set your computer too loud, you may also experience noise, so you should turn it down.

1. The computer is not cleaned up in time, too much system garbage is piled up, and the computer reflects slowly, so the system garbage and anti-virus of the computer should be cleaned up in time.

2. If the headset is damaged, you can compare the headset with other headsets or computers, and replace the headset if necessary.

3. The computer has static electricity, which is also the main reason. You touch the iron part of the computer case with your hand, and if the current sound dies down, you put a piece of copper wire, one end to the screw on the back of the computer, and one end to the ground. The results are excellent.

4. Is your microphone in a strengthened state? Solution: Remove the microphone reinforcement. Because some sound cards don't support it.

5. See if there is anything around you with magnetic fields and sound waves. Solution: Take away the electrical appliances with magnetic fields (e.g. mobile phones, fans).

6. When you are only connected to your friends, the voice is abnormal, and it is normal in the chat hall.

Solution: Please note whether either of you has turned on the amplifier or has the speaker on. Turn off if you have one.

When using speakers, you must pay attention to the placement of the speakers, not facing the microphone). In addition, if one side of the firewall is too high (including LAN users and Internet café users), different broadband users (such as telecom and Netcom) will have some voice problems.

7. When the microphone is not strengthened, the sound is very low, and when the reinforcement is turned on, there will be a lot of current noise. It's so noisy!Workaround:

Control the volume --- voice and audio device --- voice --- recording --- of the panel, click on it to look down--- turn the microphone slider to the maximum.

Generally speaking, computer audio is mostly active speakers, and there will be amplifiers inside, so noise is inevitable, and the noise of active speakers can be roughly divided into electromagnetic interference, mechanical noise and thermal noise.

Electromagnetic interference can be mainly divided into power transformer interference and stray electromagnetic wave interference. Generally speaking, the power transformer interference is caused by the power flux leakage of the multi-speaker speaker, and the effect of installing a shielding cover for the transformer is very obvious when conditions permit, which can block the magnetic leakage to the greatest extent, and the shielding cover can only be made of iron materials. We should try to choose products with big brands and solid materials, and in addition, using external transformers is also a good solution.

Stray electromagnetic interference is common, and speaker wires, crossovers, wireless devices, or computer hosts can all become sources of interference. Keep the main speaker as far away from the computer as possible and reduce the number of peripheral wireless devices.

The occurrence of such a situation has a certain relationship with the quality of the audio,So,Before choosing a sound, you must do your homework,Listen to other people's suggestions,Here I can simply tell you,Huiwei and Edifier need to tell you first,Many friends have told me,Huiwei is more difficult to push when it is actually used,The investment in power amplifier is large,Push is not good and not easy to hear。 If you're an audiophile, that's fine. Edifier brand audio ** cheap to say, dry and hard, stuffy, and distorted, the bass can't go down, the treble can't come up, many friends let me fix it, that's the problem; To tell you about the BT-Audio AB HIFI set, the AB bookshelf box is a HIFI box with excellent overall performance, reproducing the classic pure British sound.

Using super instantaneous reaction unit, the treble is not scattered, the bass is not sticky, the strong sound is not dry, the weak sound is not false, the warm and mellow sound shows the infinite charm of the **, you can feel the legendary and charming melody of the British sound, and enjoy the bloodline, sound quality, and workmanship are all excellent HIFI speakers.

The style contained in the AB bookshelf box comes from the unique design of BT-Audio's sound engineers, with a refined and elegant appearance, to create a bedroom and study desktop HIFI speaker. The first-class workmanship and sound quality have created the myth of high-end and low-price in the audio industry, and completely brought the concept of parity to the extreme!

I have a way to find the volume icon in the bottom right corner of the screen, double-click, then turn the volume of the first box on the left hand side to the minimum (audible level), and finally turn up the volume of the speaker or headphones, I hope it can help you (although there are some small vertex noises, but you can't hear them).

It may be that the socket is broken, and it is not expensive to change the sound card.

After troubleshooting the audio and headphone problems, consider redoing the operating system and sound card drivers! If it doesn't work again, it's a hardware failure of the motherboard sound card!
