There is a murmur in the audio output of the computer, what is the reason 100

The computer sound is intermittent, mainly due to the following problems:

1. The hardware aging phenomenon of the computer speaker system occurs, and the current cannot pass smoothly. (Replace hardware) 2. The power supply problem of the computer host, the voltage is not enough, which is easy to cause this kind of situation. (Change a power supply) 3. If the sound card is damaged, the sound card will also be damaged.

Replace the sound card) 4. This kind of situation will also occur if there is an error in the audio or sound card driver program. (Fix driver) 5. The data cable of the speaker or headset is not in good contact, resulting in this kind of situation. (Replace with a new data cable).

6. The host has too much dust, which is also one of the main reasons. (Clean up the dust) comprehensively analyze the above situation, to summarize the reasons, parentheses are the solution.

It shouldn't have anything to do with the hard disk.,It should be a sound card.,I don't know if your sound card is integrated.,Find the model and version number of the sound card driver.,Search on the Internet.,Upgrade if you have a high version.,Reinstall it if you don't have a high version.。

Turn the line of output and input to the output, and you may not be able to contact the number, and then you can filter out the noise in the audio!

The problem with the sound card, anyway, I just bought it, just change the motherboard.

There can be a variety of reasons for noise when computer audio output is generated, a few common problems:

First of all, there may be a problem with the audio driver. If the audio is driven incorrectly or out of date, it can cause noise. The workaround is to uninstall the old driver and install the latest version of the audio driver.

Second, it may be that the audio cable used is poorly connected or broken. If the connected audio cable is loose or broken, it is prone to noise. At this point, you need to check that the connection is secure and replace the broken cable.

In addition, the noise can also be caused by power interference or adjacent equipment. Devices such as power supply noise, televisions, or computer monitors can interfere with the audio system. Try moving your computer or peripherals, or replacing an audio cable that is more shielded.

In addition, it is also possible that there is a problem with the software settings. For example, if your computer's volume is set too high, or if the audio channel is disabled or gain is turned on, it can cause noise problems. In this case, you need to check the audio settings and make the necessary adjustments.

In short: there may be a variety of reasons for noise during computer audio output, which need to be solved by considering both hardware and software aspects. If the above methods still do not solve the problem, it is recommended to seek professional help.

When using the computer, it is necessary to keep the computer clean, properly install and maintain hardware equipment, avoid compressing audio files and bad listening habits, etc., which can reduce the possibility of noise.

There can be many reasons why there can be noise when your computer audio is output, but here are some of the most common ones:

Damaged or loose audio output interface of the computer: If the audio output interface is used for too long, there will be oxidation or loss at the audio interface, resulting in reduced sound quality or unable to transmit audio signals normally.

Unstable power supply of equipment: The power supply of computers, power strips, speakers and other devices is unstable or has common ground problems, which can easily lead to noise.

Hardware failure: Hardware failures such as computer motherboards, sound cards, etc., can also cause noise in the audio output.

Interference environments: Other devices can also affect audio quality in environments where electromagnetic interference (e.g., mobile** wireless signals) or certain other radio waves are strong.

Incorrect audio settings: Incorrect audio settings on your computer may affect the sound quality of your output.

To solve the above problems, you can try the following methods to solve them:

Check that the audio connection is secure and clean to make sure the connection is good.

Upgrade and install the latest drivers and operating system to ensure that the audio driver is intact and not damaged.

Replace and try another audio cable, especially one that is resistant to magnetic interference.

Make sure the power supply of the device is stable and avoid use in places that are affected by noise from other electronic devices and stray power supplies.

For different types of noise, you can try adjusting the audio quality parameters, mute noise reduction settings or try to improve the sound quality with special software for noise reduction.

If there is still a noise problem after trying the above methods, it is recommended to ask a professional to help troubleshoot the problem.

There are usually several reasons why there is noise in the audio output of a computer:

1.Problems with sound card drivers. If the computer's sound card driver is not installed correctly or the version is outdated, the sound card will be unstable and produce noise. You need to update your sound card to the latest drivers.

2.The sound card is poorly grounded. Poor contact of the grounding wire of the sound card will cause the sound card to work unsteadily and there will be current noise. You need to check whether the sound card grounding wire is loose to make sure that the contact is good.

3.CPU usage is too high. When the CPU usage is high, the data transmission of the sound card will be unstable, resulting in the noise of the computer's audio output. You need to shut down programs that take up too much CPU resources.

4.Out of memory. Running out of memory will slow down your computer, affecting the data transfer of your sound card, and causing noise. You need to increase the memory capacity of your computer.

5.The power supply voltage is unstable. Fluctuations in the power supply voltage will make all devices unstable, and will also affect the noise of the sound card. This problem can be solved by using a regulated power supply.

6.Electromagnetic interference. Electromagnetic waves from power supplies, displays, and other devices can interfere with the operation of the sound card, causing audio noise. These devices need to be avoided from being too close to the sound card.

7.Sound card hardware failure. Faults in some hardware components of the sound card, such as audio amplifiers and digital-to-analog converters, can also cause serious audio noise. The sound card needs to be repaired or replaced.

To sum up, there are many reasons for the noise of computer audio output, which needs to be investigated by the system. First, check for software-related issues, such as driver updates and system resource usage. Then check the hardware, such as whether the grounding wire and the power supply voltage are normal; Perform sound card inspection and maintenance if necessary. As long as you find the source of the audio noise and eliminate it, you can solve the problem of poor audio output quality of your computer.

If the problem cannot be solved after personal investigation, it is recommended to consult a technician to check the hardware and system configuration of the computer, test the sound card and other related equipment, determine the root cause of the fault and repair it, and restore the sound output quality of the computer.

The noise that occurs when the computer audio output is due to one of the following reasons:

Hardware issues: Noise can be caused by hardware issues such as broken audio plugs, loose cables, or damaged speaker headphones.

Software issues: Outdated or corrupted drivers, operating system updates, or other software issues can cause audio noise.

Signal interference: If there is a strong electromagnetic field near the computer, such as radio, mobile phone, and other devices, they may cause electromagnetic interference, which can lead to audio noise.

Audio settings issues: Incorrect audio settings can cause audio noise. For example, volume is too high or low, unbalanced channels (left and right), etc.

Noise in computer audio output can be caused by a variety of factors. One of the possible causes is a problem with your computer's audio equipment or speakers. If the device is aged or damaged, it may cause noise.

Another possible reason is a power issue with your computer. If the power supply is not stable, it can also cause noise. In addition, the computer's software settings can also cause noise.

Noise can also occur if the audio is not set up correctly or if there is interference from other apps. Therefore, in order to avoid noise when the computer audio output, we should keep the device and software updated, regularly check the stability of the device and configure the audio settings correctly.

1. Noise of power supply fan rotation: you can drop a few drops of light lubricating oil on the fan bearing.

2. CPU fan noise: You can tear the label on the fan hinge, add some oil and then cover.

3. Optical drive noise: You can use virtual optical drive software to make some commonly used optical discs into images and store them in the hard disk, or you can use optical drive deceleration software to slow down the optical drive.

4. Hard disk noise: The horizontally installed hard disk should be parallel to the chassis, and the vertically installed hard disk should be perpendicular to the bottom surface of the chassis, and the most important thing is that the hard disk must be tightened and not too tight.

5. Chassis noise: Styrofoam strips should be pasted in the appropriate place to hit the hand, and then cover the case cover tightly.

6. Graphics card fan noise: You can replace it with a new power supply fan.

Here's how to fix the noise on your computer:

1. The computer start menu ——— run——— enter "regedit" - OK.

2. Open the registry.

3. Left-click to select "hkey local machine", right-click "Find" - enter "render" (case differentiation needs to be distinguished), check the "item" and "whole word match" below to find the next one.

6. This is the item we want to find and modify, we only need to change a number.

7. Select the item, right-click - rename Change 7 after the bracket to 6 or 9, and finish.

Is this the reason why the sound of the computer and laptop is noisy and the sound quality has deteriorated?

Your fan is too loud, the CPU runs faster when you run the program, the heat increases, and the temperature rises, and the fan gets faster. You can clean up the garbage.

If there is noise, it must be poor contact, and poor connection should be divided into input and output.

The speaker tuning knob itself is poorly connected.

Audio input cable or interface.

If it's all normal, then you're in a tragic, and the bad card will also have this situation, but it's pitiful.

It doesn't work to reinstall the system, whether it's hardware broken.

But computers don't have what you're talking about.

Turn on the volume settings and turn the volume of Front Pink In down or off.

This is the driving problem, and it can be solved by driving life:

The correct way to update the driver (first make sure that the device is connected, and if you don't follow the steps to deal with it, you may have various problems):

1. Open"My computer","Uninstall or change programs (add or remove programs.)"to uninstall (the sound graphics card) the drive-related program.

2. Start running, enter INF enter, and find out that all the files at the beginning of the OEM are deleted.

3. Then restart the computer and use the driver life update to recommend the driver.

4. If the problem persists, you can repeat the above steps, install other versions of the driver, or contact a professional to deal with it.

Detailed steps to resolve the computer with noise, cracking, or no sound.

Are you talking to someone else? Maybe it's because the other person doesn't have headphones plugged in, and then the sound from your computer goes to the other person, and the other person's speaker emits the sound and then sends it back to your computer through the voice.

You try to let the other person plug in the headphones when you turn on the **, or you plug in the headphones yourself to listen. See if there's any murmur.

If there is no problem with the voice, it may be that the sound card is injured. Turn on the noise suppression function.

Workaround:

1. Replace the microphone for testing to see if the problem can be solved.

2. Whether the audio settings are correct. Right-click the Speaker icon at the bottom right of the taskbar and select a recording device.
